ColeRobbie, I can barely hang up a grow light, let alone build one ! That;s a great skill, and yes it is very cost effective. They do mark them up !!! When it comes to electricity, its worth the money for me to buy pre-made for peace of mind. As they say, maybe after the first one the rest come easy ....
Drew, I have some assorted T5's too, very pleased I switched from shop lights for tomato/pepper transplants but the basils are still puny and sparse till they move out in some real sun.
On your VHO T5's, is that 7200 lumens per bulb? I think my regular 4ft T5 is around 2000 lumen. Does that sound right?
