i've got 2 600's. ive never used the MH bulb. its either been hps or led. thats awesome that you built that. congrats. it looks good. cant comment on the c02 bag. i've never had to add it so never been needed
Yeah i just thought it couldn't hurt im going to switch to 600w hps once they are done vegging. I read somewhere that there can really never be too much co2 to a point so i thought it might increase my yield lol. I also built a scrog that i can place inside the tent and it has adjustable height. I hope it will work with new plants? Your thoughts
They look ok but, I would have waited a cpl of nodes to top first.....No biggie though!
You do have other overhead lighting right? I mean the cfl's are supplemental right?
Otherwise - time to turn on the overheads.....Be sure to optimize the distance between lights and plants..for strength of lighting.
