Hello fellow growers. So I've just purchased this 400w grow kit from HTG. http://www.htgsupply.com/Product-HTG-400w-Original-Grow-Tent-Kit.asp So first off this came with dirt bags, I'm growing dwc and they swapped me out for a bubble bucket. Here is the airstone they gave me And here's the pump Now I hooked this thing up and the bubble production sucks in a 3.5 gal bucket. My question is can someone recommend a better pump? Is this airstone good or should I upgrade that also. Most I'm willing to spend on a pump would be $100 and $50 for a airstone. Thanks everybody.
