I am in a tent with a new setup. Last one failed due to water Temps. I pose a question to the knowledgeable. Setup is 4 bucket rdwc. 4x4x8 tent. Running a small ac unit for temp control. Reservoir is outside tent. Could I grow 3 plants and locate my ac unit to blow cold air on 4 th bucket without a plant to chill the water! Does this sound feasible. Also 480 watts led for light and will scrog this grow.
