Three handy tips to maximise your yields.

For many growers the size of the final yield is massively important regardless of what plant you choose to grow or what growing system you may use. Generally speaking, maximising your yield comes with years of practise, trial and error take time because each grow you do you have to try something new and wait for the results to know if it’s made a difference to your final yield, if not then it’s back to the beginning and try another method or additive to your growing cycle then wait for the results again, this kind of process can take months even years and some growers never achieve the results they could as they often lose interest in the long process.

The tips we are about to share will knock the socks of this process and show you how to achieve maximum yields every time by supercharging your garden or grow area and because we have shared them with you here today you have just taken a huge short cut and have the knowledge that few experienced growers are willing to share.

The 3 handy tips we have to share will certainly increase yield for those that are passionate about plants.

Super Charge Tip #1 

Co2 (Carbon Dioxide) Generation – This tip is based on an indoor growing situation or outdoor poly tunnel.

Experienced growers will know that the growing environment for your plant is absolutely critical to its growth and potential yields. All plants absorb Co2 and emit oxygen in the daylight cycle so Co2 is a vital ingredient to plant vitality. Getting the correct environment can be somewhat difficult outdoors but indoors you are totally in control of all the environmental aspects of your growing area. Air flow, temperature and humidity are all important factors but Co2 induction is the game changer when it comes to increased yields. Some experts believe that using Co2 can increase your yield by around 20 to 30% and advance the growing cycle by a week.

Every grow room or poly tunnel needs fresh air input, fresh air has levels of Co2 naturally but by using Co2 generation you can easily supercharge the level of Co2 in your grow-space. Increased levels of Co2 means your plant can absorb more which in turn means better growth and better yield of fruit or whatever you have chosen to grow. Increased levels of Co2 are scientifically proven to increase bulk and mass in plants and used in conjunction with our other super charging tips you can expect to see a bumper yield.

Bottled Co2


There are a few ways to generate extra Co2 for your grow, Co2 is readily available from good grow shops or horticulture and garden centres  in bottles or tanks, you can also buy Co2 generators that involve burning propane gas to produce Co2 as well as other Fungus based chemical bags that claim to emit Co2 to assist growth.

The propane gas burners produce heat in the process which is often a problem when growing indoors plus they can also be a fire hazard, leaving a naked flame unattended for long lengths of time is not the best idea. The other point on this type of Co2 generation is that if you are going to go to the effort of carrying bottles of propane into your grow area then you may as well just used bottled Co2.

The Fungus based chemical bags have been around for some time now, to be honest we have not heard many reports of this type of Co2 generation but a quick browse round the net and the forums say they have a certain amount of success in small areas but are no-where near as effective as bottled propane or Co2 so in our view would not be suitable for a supercharged situation.

Based on very credible feedback from the experienced growers we have spoken to, the best method of Co2 generation to consistently supercharge your garden is bottled Co2. It is readily available at good grow shops and you can buy it in small medium and large bottles. This type of Co2 is by far the easiest to monitor but it requires a special gauge and timer to give the right amount of gas to your plants. For this you can buy a Unis, there are other brands around but Unis has great feedback.


Using the Unis to super charge your growing area:

The Unis is a timer and valve/gauge all in one. It simply fastens to the bottle like a regular gauge you may see on welding bottles but the Unis has a special timer that you set up based on the volume of your growing area. Once you have set it up correctly you simply plug it in and let the Unis go to work administering pure Co2 to you plants and watch them thrive. If you are using a Unis in a poly tunnel or Greenhouse then you would set a standard timer for the Unis to stop emitting Co2 in hours of darkness. If you are using it in an indoor grow room or grow tent then simply plug it into your existing timer that controls your lights so that it shuts of when the lights go out.

Unis Co2 controller for supercharging plant growth

Things to consider when using a Unis to boost your plants Co2 intake:

  1. Co2 can be dangerous in small airtight spaces so make sure your ventilation fan is working well and ALWAYS turn off the Unis when tending to your plants. Don’t be worried about it as it’s safe to use as long as you are careful and well worth the effort. Our growers have told us that forgetting to turn it off whilst tending your plants for short periods of time would likely result in headaches and you would have to spend a long time in there with no ventilation before it reached dangerous levels of Co2.
  2. To calculate how much Co2 your growing area needs all you need to do is a simple calculation, simply calculate the length x height x width of your growing area to obtain the volume, then have a look on the settings on your Unis and set it accordingly, the Unis will then give out the right amount of Co2 on time every time.
  3. Your bottle of gas will likely run out at some point, a tip here is to always replace the little seal that sits between the bottle and the Unis, this will ensure a tight seal each time you change the bottle. Another great tip that our experienced grower mentioned was to always clean the Co2 bottle and spray the entire bottle with bug killer before you take it into your grow space to ensure that there is no lodgers such as spider mite or other insects that may infect your growing space.
  4. Finally, it may not be practical for you to use Co2 to super charge your garden or grow area throughout the whole growth cycle, Co2 will increase growth massively so could leave you with over grown plants that may fill your space too much, for this reason experienced growers of plants that produce flowers or fruits would generally use Co2 from week 2(on a 8 week cycle) or after the initial stretch period that plants often show when flowering or fruiting.

Seasoned growers will measure the amount of Co2 being used in the growing area, this can be done

using kits that are single use but you can also buy a meter to measure the PPM or parts per million of Co2. A good meter to consider for this is the Titan Atlas Co2 monitor and can be bought quite cheaply from most good grow shops or horticulture centres.


Super Charge Tip #2

The second of our supercharge tips is an additive that you just cannot afford not to use. You may have already heard of it but if you haven’t you are seriously missing out. This is a readily available but quite secret ingredient that many experienced growers know and don’t really pass on the value of using it and the benefits it will have when super charging your garden.  This super additive is called Nitrazyme.


What is Nitrazyme and how is it used?

Nitrazyme is a highly concentrated growth enhancer that you use in conjunction with your normal nutrient feeding cycle; it’s made up from a selection of different elements mainly from sea plant extracts. It contains many useful things your plants not just need but actually love to have, things such as growth enhancing ingredients, micro-nutrients and bio- enhancements are all in there and available to assist in super charging your plants. The benefits of this additive is that the high concentration of these micro and bio ingredients will increase and potentiate your plants at all stages of growth, in simple terms this means that it will make your plant grow faster, thicker, stronger and healthier and also increase your yield. Not only can you add it to your nutrient solution but you can also use it as a foliar spray or mist, it forms part of the main ingredients of Rocket Fuel Spray mix but we will cover rocket fuel in its own article later.

Nitrazyme has been tested and proven at the highest levels with tests taking part on crops grown in prestigious Universities in crop growth in Canada. Below is an extract from their tests:


A brief summary…….

Ottawa Research Station of Agriculture , Canada (J.A. Simmonds & M.


  1. Nitrozyme increases the rate of germination, growth, and flowering of Impatiens
  2. Nitrozyme can shorten by four days the time required to grow impatiens seedlings for bedding


  1. Nitrozyme treated plants had 50% more leaves than their untreated counterparts, and these

leaves were one-third larger on the plants receiving Nitrozyme.

Their conclusions:

44% improvement in germination rate

 57% more leaves

 34% larger leaves

 5 days earlier flowering

 6% reduction in operation time

A full report and list of stockists can be found on the Growth Technology website. Using Nitrazyme in conjunction with our other super-charging tips will ensure you have healthier plants and bumper crops.

Supercharge Tip #3

Our final super charging tip for today is another additive that you use in conjunction with your regular nutrient solution cycle. This additive is only for use in the flowering or fruit phase of your grow and is proven to assist in providing much more yield and heavy tightly packed flowers or fruit. This additive comes in various different brands but today we are discussing the Ionic brand once again from Growth Technology, the product is called Boost or PK boost and is usually only used in the final few weeks of flowering. Boost is used alongside of your normal bloom and is a great way to add extra phosphorus and potassium into your nutrient solution. It works great with Ionic bloom but to be fair will work just as well with any brand of Bloom and bloom stimulators.

Ionic-Boost- growth enhancer

Using Boost alongside of Nitrazyme and Co2 will all serve as a fantastic way to enhance your crops final output and supercharge your garden. We have taken these tips from seasoned experienced growers from Holland, USA and Canada. The growers we connect with have many years in producing huge yields and have spent many years going through trial and error of many different products, growing techniques and growing systems.

Nutrient Solution in Hydroponics

In this blog we are having a look at nutrient solution in Hydroponics, if you are new to Hydroponic gardening then this is a must read. If you are a seasoned grower then look at it as a refresher, sometimes it’s helpful to think back to basics. It’s not really possible to cover every aspect of nutrients and their uses in one article as it’s a huge subject so this is kind of a detailed overview.

There are various different methods of Hydroponic gardening but regardless of which system you are using you always need a nutrient solution. For the total newbies among us, in simple terms nutrient solution is simply water with added nutrients and enzymes and that’s about it, just because you are growing with Hydroponics doesn’t mean it has to be over complicated. The nutrient solution is either pumped or delivered by hand to the plants depending on what system and grow medium is used.

Water Quality

There are a few important things to consider when preparing a nutrient solution; water quality varies greatly depending on where you are in the world so one of the first things you need to consider is whether you are using hard water or soft water, a rule of thumb is that if you find it hard to get lather when using soaps or washing up liquids then you most likely have hard water. Usually your local authority will have advice on water quality or search online to determine which type you have. Many good hydro shops will be able to carry out a simple test to determine the acidity/alkalinity of your local water.

It’s important to find out which water you have as this will decide which type of nutrient you need to be adding, many nutrient companies supply both hard and soft water versions but it is also possible to buy universal nutrients but I wouldn’t advise it, putting a little effort in to determine which water you have will make balancing your CF and PH levels within your final solution easier so it’s worth the effort.

Using fresh clean tap water as a base for a nutrient solution is nearly always best; using filtered or bottled water is usually not necessary and can in fact cause a nutrient deficiency in plants. There is an exception to this rule, if your water is so hard or so soft that it is not possible to get a steady PH or CF reading then it is worth considering a reverse osmosis system but that is a subject on its own which I will try and cover at a later date.

Making a mix:

The principles for making a mix or nutrient solution is pretty much the same regardless of the actual system you are using but the steps below are based on using NFT system in a poly tunnel or indoor area.

You will need a CF truncheon and a PH meter to accurately measure the levels at the end. There is more on these tools below.

Fill the reservoir or tank with fresh water, cold is best as it contains more oxygen, warm water destroys the oxygen in water so if you need to add hot do it sparingly, you are aiming for a water temperature of around 60 degrees but as a guide tepid cold is ok but not freezing cold as it will shock your plants on circulation.

By this time you will have already decided which brand of nutrient you will use, some nutrients come as a single formula some are in A and B form. Add the nutrients before adding any enzymes or other additives.

If you are using A and B it is important that you do not mix them together in their undiluted form, add the A part to the water first then mix thoroughly and then add the B part and mix again. Rule of thumb here is don’t put too much in at once, it’s easier to slowly build up the levels than to put too much in and have to drain the whole thing and start again, checking as you go by dipping your truncheon/meter in the water.

Nutrients are measured using a CF truncheon or meter (readily available at all good hydro retailers), the level you need to set the solution at will depend on the plants you are growing  and the stage you are at within the grow cycle, many plants like different strength foods so it’s difficult to generalise this part of the process. You will most likely need to change from Veg to Bloom during the grow cycle but again it depends on what plant you are growing, the principle for mixing is still the same.

Adding Enzymes

Once you have added the nutrients whether in single pack or A and B you will need to look at adding some enzymes, unlike soil growing you have the control over which enzymes you use and how often. Enzymes are important to hydroponics as it puts all the micro-biological chemicals that plants need into the solution. Check with your hydro supplier to see which enzymes suit the plant you are growing best. My personal preference is Atazyme which is a highly concentrated liquid form of natural enzymes.

Follow the instructions on the back of the bottle with regards to dosage, usually about half a ml per litre in the reservoir, adding a small amount of luke warm water to the enzymes will help the solution break down the enzymes and make them more readily available to the plants quicker.

Checking the PH level

Once you have vigorously mixed the solution the final thing you need to do is check and maybe alter the PH level.  Depending on if your water is soft or hard you will need to stabilise your PH using either PH Up or PH down. Most plants like a PH of around 6.0 but again this varies from plant to plant. Add the PH stabiliser in small amounts, checking frequently with your PH meter. Once you have the desired PH you can then circulate the solution to your plants. See further info on PH below. In NFT and other hydroponic systems it is recommended that the PH is checked and adjusted on a daily basis to maximise nutrient uptake by the plants.

Nutrient Maintenance

On a NFT system and all Hydroponics system’s it is recommended that you totally replace all the solution at some point during the grow cycle, I strongly recommend that this is done on routine intervals once a week.  Replacing the solution every week means that you replenish everything within the tank or reservoir and are keeping the solution clean and fresh which should mean a healthier plant and bigger yields.

Check then check again

It is worth taking time to get your solution correct before you circulate it, remember that although you can add some additives in between the weekly pump out and clean cycle like Oxygen and PH stabiliser and even fresh water to your solution after you have circulated it, you cannot add nutrients once the nutrient solution has been mixed and circulated, so if it’s too low you cannot adjust it mid-week, to adjust a low nutrient level (CF) you will need to replace the whole solution. After circulating the solution for a few days it’s possible that the nutrient level will rise, often due to the plant taking up the water and leaving the heavier salts in the tank and perspiration. If this is the case fresh water can be added to lower the level back to an acceptable one, you will also need to re adjust the PH level.

Nutrients will not breakdown if you add them afterwards, even by one day later, adding nutrients to a circulated solution will usually give you a nutrient imbalance and quite possibly a high and possibly toxic amount of salts to the plants. So rule of thumb is to get it right before circulation.

About CF’s and PH in Nutrient solution

When you add the nutrients to the solution you are basically adding salts, these are measured in PPM or parts per million. Different plants thrive at different CF levels so it’s important that you do your research on the actual plant you are growing and find out what levels of CF they thrive on. If your CF is too high and not corrected the plants are likely to perform poorly and possibly die due to high levels of toxic salts.

PH Meter and CF Truncheon

PH measures the acidity or alkalinity of the water; this can vary greatly from area to area. If your PH is not within the acceptable range then the plant will not be able to take up the all-important nutrients and enzymes. One of the positives of hydro gardening is that both the PH and CF can be easily monitored, controlled and corrected, something not possible when soil gardening, well at least not to the same consistent accuracy. A CF meter or truncheon and a PH meter are both must have tools for the hydroponic gardener.

Hydroponics All You Need to Know

Hydroponics is regularly used by growers around the world to produce fast growing crops with a high yield. Although the name sounds quite high tech and modern, soilless growing has been around for centuries, researchers as far back as the 18th century realised that soil itself was not essential to plant growth. In plant growth soil is simply a medium or reservoir, something to hold the nutrients that the plants need to grow, hydroponics replaces the use of soil with other mediums such as rockwool, coco scuff or pebbles. Replacing the soil with other mediums has many benefits as it allows the grower to be in total control of not just what nutrients are available to the plants but when, in soil growing it takes a very experienced gardener with a keen eye to know just how much nutrient a plant might need and how often, with hydro-systems the nutrient can be closely monitored using meters to measure the CF (salt minerals content) and the PH(acidity) all which are vital to premium plant growth.

There are many different types of hydroponics systems used today, much research has been done to advance the science of hydroponics into a simple but effective growing system that can grow pretty much any many plant to great success. With a little know how and some simple materials available at most DIY stores it is possible to make a Hydro system but before we get into that lets have a brief look at the ready made systems available and how they work.


Nutrient Film Technique is amongst the most commonly used hydroponic systems.

To set up an NFT system you would need:

  1. Purpose built trays or gulleys to sit the plants on.
  2. Reservoir or tank to house the solution
  3. Submersible pump and piping system for irrigation.
  4. Spreader mat.
  5. Growing Medium
nutrient film technique

So how does it work? Plants are suspended in a medium, most commercial growers use rockwool blocks for this but baskets of clay pebbles are also favoured. A nutrient mix of specially formulated liquid fertilizers is mixed in the tank (A) because the solution is based in clean water there are a lot of basic enzymes missing from the solution, these are added separately usually in liquid form, there are many different brands on the market and experienced growers tend to have their own formula or mix, this is often a closely guarded secret as the correct solution mix with the correct enzyme additives can make a huge difference to the final yield of the plant. The solution is circulated from the tank using the submersible pump(B), up to the growing tray and is pumped in at the top (C) the nutrient solution then runs down the tray(which has a layer of spreader mat on top) creating a film of nutrient, this is known as nutrient film technique. As the film runs down the trays the nutrients pass over the roots of the plants (D), the solution then falls back into the tank (E) to be re circulated back to the plants. Some growers use the same system but only pass the nutrient solution over the plants once; this is known as Run to waste NFT.

Flood and Drain

To set up a Flood and Drain hydroponics system you will need:

  1. Purpose built trays or gulleys to sit the plants on.
  2. Reservoir or tank to house the solution
  3. Submersible pump and piping system for irrigation, with one way valve.
  4. Growing Medium
flood and drain

Flood and Drain is a passive system as is NFT but there are differences in how the solution is delivered to the plants.The nutrient solution is mixed in a tank (A). As we have seen above NFT provides a film of nutrients that passes over the roots to allow them to absorb the solution, with Flood & Drain the plants are set in the chosen medium and then they sit in the tray or gulley without any solution, the nutrient is usually pumped up to the trays or gulleys from the tank using a submersible pump, not all F&D systems use a pump some are gravity fed but either way the mechanics are the same.

The pump will allow the trays or gulleys to be flooded with a predetermined amount of solution through a one way valve(B) but unlike like NFT or other passive systems the solution is held in the tray or gulley for a time to allow the medium to soak up the solution and feed the plants(C). The solution then drains slowly back into the tank and the process starts again.

Dripper System

To set up a Dripper hydroponics system you will need:

  1. Purpose built trays or gulleys to sit the plants on.
  2. Reservoir or tank to house the solution
  3. A timer controlled submersible pump and piping system for irrigation,.
  4. Growing Medium
drip system

As with all the systems we have looked at so far the dripper system has a tank to store the ready made solution(A).The solution is pumped up to the growing area using the submersible pump(B) but with this system the pump is timer controlled with flow controls added to the irrigation pipework(D) to allow a predetermined amount of solution to be delivered to the plants(C), this time rather than run down the tray in a film or as a flood the solution is dripped directly on top of the medium(in this case Rockwool is used) and over the roots of the plant, it then makes its way back to the nutrient tank and the whole process starts again(E).

Deep Water Culture (floaters)

To set up a Deep Water Culture floater system you would need:

  1. Purpose built pots to sit the plants in.
  2. Polystyrene Floater boards
  3. Reservoir or tank to house the solution
  4. Growing Medium
deep water culture

A deep water culture system is pretty similar to a standard flood and drain system, a tank is filled with a premixed solution, the plants are sat in a pot with a medium for support and to absorb the solution.The pots are inserted into a polystyrene floater board which keeps the pot floating on the solution rather than sitting on a tray or gulley. Smaller growers would  empty the tank manually periodically but larger growers would adapt the flood and drain system to automate the delivery and drainage system. An air pump is defiantly needed in this system as the roots tend to be totally submerged within the solution so will struggle for oxygen, as we will see later on oxygen is vital to all growth whether its hydro or soil based.


To set up a Aeroponics system you would need: Purpose built baskets to sit the plants in. Purpose built Aeroponics chambers. Reservoir or tank to house the solution Growing Medium. Pump Irrigation pipework with atomiser fittings Aeroponics is quite different in one way but also similar in other ways to…
