You won't have ph problems w/waterfarm if you follow my instructions on previous thread and you can use this for 4 or 8 buckets. the key is to raise the res 7 inches off floor so all nutes drain into buckets (no nutes in res) and to check ph, you lower res onto floor so nutes drain back to res, then check res ph. I also checked my system by checking the ph after lower res, and then I drained system and checked ph again, and it was the same.

That's not to say I don't adjust ph, because I do. I've learned to adjust ph below 5.7 and above 5.9, just alittle adjustment at a time.

Listen, these guys and gals are correct. You can build your own system for 1/3 to 1/2 the cost of waterfarm, that works as well or maybe better than a waterfarm. It just depends on you and your growing environment.

I just built 2 bucket bubblers for my 2 mothers (cheap to build), and I'm having great success with them.

Again, It just depends on you and your growing environment.

What ever you do, follow ZANDOR's advice:

"If you go cheap, you grow cheap"

Do it right the first time, otherwise you'll wish you did. I made that mistake.
