Im doing a report for a class about marijuana growing and I know some people use certain chemicals to grow it. I was wondering if anybody knows some of the chemicals?
Um, hydroponics requires a nutrient solution that can come from many sources.
Sometimes white flies or aphids can be a problem in the greenhouse or indoors. They can be controlled with horticultural soap; or a systemic chemical like ‘Marathon I’. It leaves a nasty residue in the plants though it would be easier to apply.
