hps

So I started germinating my plants on june 1. 2 days later they were planted and two days after that they sprouted. I have had them under CFL the whole time, but my 2x4x5 grow tent and 400w hps light arrived yesterday. My question is... When do I switch them from CFL and put them in the tent...

Will a new bulb help at all? It seems like every other time the ballast is to fire my hps that the it fails and I have no idea why. When it does I just unplug my ballast, unplug my fan, them plug the ballast back in and it starts up. I think it has something to do with the fan running at the...

Well the good news is im back and i wasnt gone due to law or anything although i was getting abit paranoid at times haha I was gone due to having a new job and not finding time to get a new grow started, had abit of a falling out with boss and left but then it was fishing season so that delayed...

So I searched the forums and didn't find anything on the (economical) VIVOSUN VIVOSUN Hydroponic 400 Watt Grow Light Digital Dimmable Ballast HPS MH System I found it on Amazon and it has pretty good reviews. IT also comes with two bulbs: VIVOSUN 400w HPS bulb, 400w MH bulb. I'm wondering, I...

Does anybody add it or should I just go all HPS. I have a 600w and 400w in hoods running through a charcoal air filter. :thanks:

:welcome: Moving swiftly on from my last journal this one will be a run much the same - although I will be flowering out two plants this time instead of just the one. However, the aim will be to pull 400g from each plant using only the 600 watt hps. For this growwhich could be a long one;)...

I'm just looking for a little input here. This is a indoor setup, (2) 4x8x8 tents, soil, emerald harvest nutrients, dominator xxxl hoods, MH and HPS lights. I'm currently running a 1000w MH in my veg tent. It's getting close to flower time and I'm a little undecided on how I want to run...

Okay so I have prided myself of directing allcof my efforts to find the weed that has given ME the best buzz, best taste, best look, just the best of the best! And buying 4-8 different strain 8ths a week has given me a very wide taste-range! From all-over Michigan I have visited dispensaries...

Waddup waddup waddup. Back again, with a new grow, and a few new tricks. Made some changes to the setup, runnin separate exhaust arms for my carbon filters and light hood. Went all semi rigid 6 in duct, built a intake air filter, and sealed off the vent window. Added an occilating tower fan and...

hi ive been using 2 mars II 900 for a couple of years now, have tried different strains but never experienced the yield I got from hps. The buds were good to smoke but were light. The last few grows I have used 2 400hps lights as supplemental lighting to the mars, I run 1 for 4hrs shining from...
