Fortify Your Rootzone With Billions of Beneficial Microorganisms - Instantly!

Biosys is proudly endorsed by growers of world-record breaking fruits and vegetables. That's because it's the ultimate all-in-one microbial product that delivers billions of highly beneficial microorganisms to your substrate. These little creatures work with your plants to enhance health, growth rates and yields. The great thing is, it's an absolute doddle to use and it saves you the time and hassle of brewing microbe teas. Just add it to plain water, stir it and you're done, although we would strongly recommend using Ecothrive Neutralise with Biosys to avoid the chlorine/chloramine in tap water inhibiting these microbes. It really is that simple. To give your organic garden an even bigger kick, try Ecothrive Charge too!

How Biosys Works

Biosys has been formulated after years of testing and development by the team at Ecothrive, makers of the much sought-after, and highly regarded, 'Charge'. The idea was to create a complete product that would deliver multiple types of beneficial microorganisms at once, and in a way that was quick and easy to use. To maximise the results, Ecothrive have also added a complex mix of growth enhancing, complementary ingredients – enzymes, amino acids, proteins, humic acids, carbohydrates, yeasts and seaweed extract.

How To Use

How to Use Biosys

Always dechlorinate your water by leaving it to stand over night before adding Biosys. This is good practice generally and will create a friendlier environment for the micro herd. Avoid using Biosys with nutrients at ECs over 1.5 (plus the base level of your tap water).

For Seeds and Cuttings

Use at 1g per litre of water. Give your rooting plugs a good soak for 15 minutes and then squeeze out the excess liquid before continuing as usual.

For Potting On

Add Biosys at a rate of 1g per litre and then water it onto your plants after re-potting. This will help to colonise the fresh substrate.

For Established Plants

Use at 0.5g per litre of water. If you want to use Biosys alongside your other nutrients, drop your feed down to half strength; otherwise, use it with plain water. Do this once every 1 to 2 weeks.

Biosys works a treat in re-circulating systems - just make sure that you drop the dosage down to 0.25g per litre and keep your nutrient solution aerated. Do this once every 1 to 2 weeks.

As an Anti-Stress Tonic

Biosys can speed up the recovery of stressed plants. Just add to plain water at a rate of 0.5g per litre and apply at 5 day intervals.


You can add Biosys when performing a weekly flush at a rate of 0.5g per litre (or 0.25g per litre in recirculating systems).
