Microbial is used to stimulate a plant’s inbuilt immune system, thus improving overall plant health and increased resistance to attacks from pests and diseases.

With soil based horticulutre many of the bacteria present are beneficial to plants in terms of breaking down organic matter and enabling the mineral elements contained within to be readily absorbed by the plant. In a hydroponic environment these beneficial bacteria are not present, therefore the potential for problem airborne or soil borne micro-organisms attacking hydroponic crops is very high.

Even with a good preventative maintenance program in place, problems can still occur such as algal blooms, pythium outbreaks, mould and mildew attacks. These can occur because of pH shifts, lack of oxygen, poor environment control and imported organic materials transferred by growers from other sites. Indoor hydroponic environments are especially at risk to such pathogens, and the grower must effectively become mother nature by instigating an effective preventative maintenance programme.

Microbial is a wide-ranging aqueous solution derived in part from naturally occurring plant extracts. Microbial is non toxic to humans, animals and plants and is totally biodegradable and environmentally friendly.

Microbial acts as a micro-cleanser and plant rootzone conditioner, which cleans and rejuvenates plants. This allows the plant to naturally withstand attacks from common pests and biological contaminants like bacteria, fungi, algae and viruses.

Before Microbial the only method of treating the above problems was by using heavy chemical sanitisers, fungicides and pesticides which in some cases do more harm than good, especially to crops that will eventually be consumed by humans.

The horticultural industry as a whole will benefit by the use of Microbial in their respective growing environments because the use of pesticides, fungicides and other harmful chemicals can be reduced, if not totally eliminated, in turn reducing grower overheads and also benefiting the environment we live in.

Microbial is becoming the preferred method of overcoming plant related problems, and should be adopted by all growers in the horticultural industry as an integral part of the grower’s overall preventative maintenance programme.

How to use Microbial

Microbial can be used as a rootzone or plant conditioner. When applied at the recommended dosage rates, Microbial will naturally aid plants to withstand attacks from most common pests as well as fungal and bacterial pathogen outbreaks, including fusarium, pythium, rhizoctonia, phytopthera, sclerotinia.

When added directly to plant nutrient solutions, root zone health will be improved enabling the rootzone to uptake oxygen, nutrient and water at a much faster rate.

Tank dosing

Add 1ml to 2 litres of nutrient solution on a weekly basis or whenever solutions are replaced. Apply this rate for any additional water added to tank after initial dose. Continued use as a maintenance measure will assist the plant to keep most problems from developing at any stage of its growth. For intense dosing of media systems to assist with rootzone problems, total saturation of the media weekly with a pre dosed tank mix of 1ml per litre would be advisable. One application should be sufficient but daily dosing would be advisable until an improvement in the plants health has been observed.


Microbial when applied directly to foliage or stems rejuvenates the plant allowing it to naturally withstand many moulds, mildews and algae outbreaks. In tests to date Microbial has shown that it enhances plant health and improves immunity against botrytis, blight, fusarium, leaf mould, stem rot and powdery mildew.


Dilute 1 part Microbial to 5 parts water into a fine mist sprayer. Apply directly to all leaf and stem areas of the plant.Applications may be repeated once a week at this dosage rate as a preventative maintenance measure.

Microbial has shown to be an effective plant conditioner that improves plant health. Healthy plants often naturally withstand outbreaks of many common pests including fungus gnats, aphids, spider mite, and whitefly.
