I use dishwashing soap as a way to break the surface tension in water. It seems to make it “wetter” for easier absorption into the soil. I water the marijuana plants by hand and use only organic soil and nutrients. What’s your opinion on using wetting agents and detergents?
Soap and detergent both have a “wetting agent” that breaks the surface tension of the water. Rather than beading on the soil, the water is absorbed by the planting medium. In general, wetting agents used at the same time the planting mix is first being watered. The planting medium usually accepts water easily after that. If you want to keep your project organic, be sure to use an organic wetting agent. You can find many different organic products made specifically for horticultural use. It’s definitely better to use one of these if you use wetting agents routinely.
