I think I'm going to have to upgrade the pump I have now. On the highest setting, I don't get much pressure coming past the check valve. Water flows alright, but not at a fast enough pace. And with only 1/2" plumbing, this isn't a good sign.

I'm looking at something over 1000GPU, and a max head of about 13-15'

They also have sump pumps for a reasonable price, 1/2HP that pump much over 1000GPU, but i'm sure use much more power.

WeedTree's Reviewed by WeedTree's on . Building a Aeroponic Prototype -- Need Help! Hello fellow Growers! I'm begining a prototype Aeroponics setup to grow a large Tomatoe (And soon Marijuana) plant from seedling to flower. I will be using a 5+ Gallon bucket for the initial Resevoir, and a smaller bucket which will sit on top to house the misters/sprayers/grow chamber for the plant (Or Visa Versa - 5 Gallon on top, Bigger bucket on the bottom) The resevoir will hold the pump, an airstone, and said outfits for wiring as well as tubing. The nutrient will be pumped up Rating: 5
