mubo Posted March 6, 2022 Share Posted March 6, 2022 I’m in the same sort of boat where it comes to size of LEDs, i have a space of 2.8m x 3m so was going to fit 4 fixtures in there but what 4? I’m now swaying to the 600w lumatek pros. 1 Link to comment Share on other sites More sharing options...

I can happily keep all the windows shut for days at a time and the plants couldn't give a fuck. On the flip side, it'd be interesting to know what the O2 levels are in our houses. When you've got a few areas going it must be higher than average, unless it all cancels out somewhat with the leccy use. Link to comment Share on other sites More sharing options...
sweettooth Posted March 7, 2022 Share Posted March 7, 2022 @mysticriver I bought a co2 meter and left in various rooms, sat at 400ppm most days, only went upto 1200 when I was cooking. fyi. the only reason I use it and said many times before is its cheaper to supplement co2 rather than always use a heater and constantly extracting as I'm a loft and it's cold. come the warmer months I'll be ditching the co2 as I'll be able to temps up while extracting 1 Link to comment Share on other sites More sharing options...

Im thinking of doing the later myself tbh with an Ecotechnics Unis and a fuck off great bottle of CO2 especially if your saying it cheaper than running the heater - its a no brainer as long as the CF minimum run speed is hit Link to comment Share on other sites More sharing options...
sweettooth Posted March 8, 2022 Share Posted March 8, 2022 @BaronVonGreenBack Co2 doesn't control heat. my loft is about 2 degrees atm. if I turn my extraction down to keep the heat in, my co2 levels drop and growth sloes or even stops. I could keep my temps up by constantly running a heater but I'd have to have at least a 2.5kw heater on 25 hours a day, that's expensive. @zen-ken yes, my tent is sealed up tighter than a nuns vag. I use a ram co2 controller and a large bottle of co2. bottle refills cost £30 a time and last generally 2 weeks, need a krge dehumidifier to keep vpd levels correct as RH goes sky high in a sealed area. leds keep the taps down I couldn't do it with HPS, would defo need aircon but that's another expense. my temps sit between 28 and 29 and RH between 62 and 66. my co2 ppm is currently set at 900 but I will start ramping it up as flower continues upto 1500ppm, also helps me get the most out of the 1000w led although I'll only go 700. This is the 3rd grow using this method and I think I've found the sweet spot, mainly from changing my cal:mag ratio with Epson salts, they've never looked better once I setup my auto feed system amd run multiple fertigations a day, they is gonna go mental. 2 Link to comment Share on other sites More sharing options...

I can imagine you need a serious dehumidifier..... but your growth will be explosive. Got the old grey matter thinking about this again Link to comment Share on other sites More sharing options...
sweettooth Posted March 8, 2022 Share Posted March 8, 2022 @zen-ken 50L unit now. old 12L would cut the mustard (although depens on number of plants, better to over spec than have it over worked) have the 50L hanging with car straps to keep her quiet. It is an extra 800w of power but isn't used all the time. inkbird ihc-200 runs it 2 Link to comment Share on other sites More sharing options...

mubo Posted March 13, 2022 Share Posted March 13, 2022 I think I’m going to start with 2 600w pros first to see how I get on with them. I had a look at the Gavitas the other day and they look good, but the price 1 Link to comment Share on other sites More sharing options...
Chongmabong Posted March 16, 2022 Author Share Posted March 16, 2022 @mubo thats good at least you made the choice im still undecided so I just got new lamps for next grow I probably wait till end of this year now to see what new or improved ones come out. Yes the Gavita is ment to be the bollox bud i only need one light so although pricey probably a good investment especially if you use it just to flower. All the best with your new lights when you get them. 1 Link to comment Share on other sites More sharing options...
mubo Posted March 16, 2022 Share Posted March 16, 2022 @Chongmabong I wish I had made my mind up, I’ve got a 3m x 2.8 meter area, so it’s 2 x lights and it comes down to either the lumatek 600w pro 2.9 or the big wide 1000w pro. Then I’ve seen some good things with the Gavita but the cost just to dim it is just stupid 1 Link to comment Share on other sites More sharing options...
