blunted - what size pots are those.. thats kinda like the system i am dreaming up. any more info on it? oh an size of res, frequency of feeding.. stuff like that.. thanks..
10" pots
4x4 tray
40 gal res
1000w hps
300gph pump for drippers
200gph to mix the res
airstone
feed twice a day for 2 min
Hope that helps!
In my veg area I don't use a pump to mix the res, the air stone works ok for a 18gal res. But in my flower res it doesn't work so well (40 gal). Around the edges of my res you would be able to see a thin film forming on the surface if I didn't run my pump. With the pump running its like a slow whirlpool. Some people only run the second pump during feeding. I run my second pump 24/7.blunted - question. why have a second pump to move the resivor around. doesn't the air bubb;ers do enough to keep the res mixed? or you just put it in as a precaution?
