honestly, please dont flame me to death if some of you have a good relationship with Rex Grigg but i did some looking around on his forums. Basically he has to build the thing, and then he explains in a thread that he is always really busy and doesnt have a lot of time to build regulators and only ships once a week. I wish I knew this beforehand because I would NOT have ordered from the guy. I would have gotten the same regulator from greenleaf and it would come in less than a week. Not to mention he hasnt returned my last email and I have no way to know when the unit is going to ship. And as many of you know, the guy is a bit on the arrogant side.
Its my own fault, believe me i know. Now I get to watch my plants rot because i dont have the time to make a DIY.
