Hi Victor, what do you mean around the bottom of the plants? do you mean the tops of the plant pots or do you mean cover the table around each plant pot?Its not the table you need to cover, its the area around the bottom of the plants , no light, no algae growth. VV
Cheers Vicyep, the top of the pots. What you are trying to do is block light from getting to whatever medium you are using. This will stop algae from growing there. H2O2 in the resevoir twice weekly will control it, and most other pathogens, and add oxygen to the roots. VV
this is a hydroponic not organic, plus hydrozyme can be used with h2o2 but at a small dosage.remember h2o2 will kill all beneficial fungi as well
