Plants evaporate almost all of the water they drink. The math is simple from there on 😊

You want one that can hold at least a gallon of water so you only have to empy once a day, or if you get one with a drain hose then it doesnt matter

disc filter 120mesh! question on installation!
Please tell me where the filter should stand? before or after the pump? a drip irrigation line will also work! I hope the filter will help prevent clogging of the dropper hose! And my 600 l/h pump will it be able to work with this filter?

Humidity and Ph level
Having trouble getting my humidity in my hydroponics setup above 40%. Got some advice that I should raise my pH in my reservoir from 5.8 to 6.5 to better meet the plants needs in lower humidity. Is this true?

Soil heater
Got a soil heater today, wrapped it around the bottom of my fabric pots. Is that the way I’m supposed to do it? There weren’t any instructions on the package & I’m not big on YouTube tutorials. Ive also been playing music for them during day light. Do any of you do this?

Incredibly low CO2 levels
After adding an A/C to my tent I began using bottled CO2 like never before. 20lbs in 5 days. Without adding, my CO2 is at 4 ppm. Yes, four parts per million in the dark. How can this be possible if the air in my house sits at 400ppm? I read that photosynthesis stops below 200ppm
