Whytewidow How much would that strip setup be for my space and how many total watts ? How many gpw do you think I could get with this setup compared to a cmh Thanks David

I'm still trying to figure out the grams per watt figures.. From what I've read hps is supposed to get 1 gram per watt, cmh 1.5 per watt and led up to 2 grams per watt all growing conditions being equal. Maybe I have this wrong and I've been reading to much marketing

Maybe supplement with some red Leds during flowering to get closer to the hps reds?

You think I can get 8 pounds with the right strain and conditions with 4 1000 cmh lights? That would be amazing

Need to do more research but seems like 1000 watt cmh will be perfect. 12 315 cmh lights will cost me $3600 4 1000 watt de cmh $1460 Less replacement bulb cost and much easier to deal with 4 lights than 12. Maybe the 12 lights will give better coverage but will also be a pain to work with

Grower's Choice 1000W Double Ended CMH All in One Fixture with Bulb $364 There might be cheaper or more expensive ones but found this on a Google search...can't post links

Thanks for all the great info. What about 4 1000 watt de CMH fixtures? Would they better than 1000 watt de hps light for heat and efficiency? They are pretty reasonable at $350. About the same price as a 1000 watt de HPS and sun system 315 cmh

I think I can get 4 1000 watt de fixtures for about $1400. 20 8 QB96's and 10 HLG-320H-54's will cost aprox $2900. 12 315 cmh's about $3360

Thanks everyone for the great feedback and ideas. I am going to add a c02 propane generator to maximize the light potential. Has anyone tried to water cool the qb96's and push them harder? Someone recommenced I get 4 de 1000 hps lights or 12 315cmh setups for this space. Where I live i'm...

I have a free Daikin 2 ton mini split and I install them for a living.. You're saying that the unit won't put out much heat because it's not constantly running? The shed is only 9*9 so that unit c02 unit is probably overkill but it might be more cost effective than using tanks

Does it cool output or does your minisplit take care of that?

What type of unit do you use for co2 via natural gas? I've seen a cooled co2 generator for around $300 on Amazon but it doesn't get good reviews. Only propane has in my area so hopfully there's a conversion kit

Have a 9x9 space and want to build a led setup 8 QB96's V2 8 HLG-320H-54's My plan is to add pc fans and try to run the QB's at 300+ watts each to put out 2400 watts of light over my growing area. Does anyone see any problems with this setup in regards to driving these boards at this...

I'm in the northeast so it can be pretty cold. I plan to install a two ton mini split and probably a floor model dehumidifier if that will be sufficient. I'm getting the shed sprayed with foam insulation but I'm thinking I might have a problem pulling make up air from the outside cold weather so...

Budget isn't an issue and I'm still trying to decide the media.. I'm thinking about a Hydro setup with dtw. looking for a system with the lowest maintenance but fastest growth and biggest yield. Its a shed with 8ft walls plus pitched roof Putting in a 40 amp service and quality water is plentiful

I have actually changed my plans and have decided to grow 6 plants in a room 9x9 . I'm looking at a few light schemes and wondered what you guys think. I'm thinking about getting one of these three systems but i'm trying to figure out which one would produce the best results quality and...

Thanks for all the input. You guys are great!!

I'm legally limited to 6 plants and want to maximize my grow space My idea is to setup 6 grow tents with one plant per tent and a 315cmh. Would a 2*4 or 4*4 tent be best? Will it be possible to get a pound per tent/ light with the right strain, training and grow conditions? Thanks in advance...

Was wondering how big your room is to harvest 20 pounds every ten weeks?
