mines is expose to the light. i put a net over it so little bugs such as ants can't get in. I will cover it as soon as i get the water pump and nozzle. all these time i thought dirt was sucked in by the air pump and flowed through to the air stone, then to the water. I'm doing a manual feed. I just think that using the water pump attach to nozzle will be much easyer to feed in scrog instead of pouring cup after cup.
YASoob Reviewed by YASoob on . air stone used for reservoir g/b? i have a reservoir that i use to feed my plant. Its a 5 gallon bucket and i use about 2 gal every feed. I use air stone and air pump to air the water mixed with nutes. Is this good? can anything bad happen? (i also notice that the water seem to be more dirty. I don't know why. Before i could see the air stone clearly, but now i can't see it so well) Rating: 5
