I'm new here so take it easy on me. I'm setting up a room so I can help some friends out and myself with medical use. I'm going to use clones so that is covered. I'm not going to use hydroponics but the standard way as I like to think of it in a 5 gal pot. I've done a lot of reading and it seems the best is a Metal Halide1000w ballast with a (blue) 1000w blub to veg. the plant and I'm looking for a 940W conversion blub to flower. I know lots of blubs use the same technology in making them but I would like a consensus on what make is best Phillips, Hortilux, etc. I have a friend who is going to teach me the ins and outs of what he has found from his trial and error. But he has his oppinion on what is best I would like some outside oppinions also. I don't like the hoods or reflectors he is using I like the square retangle kind better than the round ones. The square seems to put out more light then his. Am I wrong here? OK now I need to know what kind of reflector I should get there are so many. Is venting through the hood the way to go? It seems that there would be a lot of wieght to pull up when I need to raise them by hand. He uses fans and 8" tubing to push the air around on the floor plus regular fans on stands and a 8" tube at the top of the room to suck and vent the air outside. OK now what kind of fans with tubing should I get and what size 6 or 8"? He uses CO2 by turning off the fans and just turns the CO2 on blowing around the room for about a minute then turn the fans back on in about 15 minutes. I wondering if I should get the CO2 system with timers?
OK now where do I find all these items. I have searched the net and I can't find the particular ballast I want Diamond model DMH1000 and the 940w NH940B(F)CE conversion blub is the one he suggests to use. If there is better or cheaper ones that works great let me know. InsideSun (or bulbs hydroempire) doesn't have what I want but have read here that what they do provide are good. They don't have a 940 w conversion blub. Now is this conversion bulb a HPS? I do know it is a Metal Halide ballast Hortilux 940w BT37 conversion bulb I read that on the box when I was there last but it didn't say it was an HPS. I would like to use an HPS they seem to work better a better yield as I have read.
Is all HPS bulbs long and not the bt37 size?
OK I think that will be good for now.
Any help would be greatly appreicated.
Thank you all for all the info you can provide.
