Cannabis Grow Rooms

Has anyone heard of Green lights ? A friend of mine mentioned that they may be able to be used during the 'lights off' period without upsetting the plants cycle. I work odd shifts and am sometimes not able to get to my girls to do gardening during 'lights on'. Any help would be appreciated.

Gudday growers, I have a cupboard measuring about 500w, 700d, 1200h I want to use this area for clones at one stage, and a drying area at another I cant fit a full length fluro in there I was going to get a fluoro mount with 4 x 2 foot tubes... but they seem pricey But would I be better off getting a single CFL globe 14000k, it seems to be cheaper and more available Will the 14000k be ok for vegging beyond starting clones? Incase they have to stay there a bit longer to wait for the flower tent to finish What would you use for lighting clones in this space? Cheers

I am really skeptical about leds, saw few independent grow tests 420 maz...and the more wattage expensive leds seems to be getting similar results. However most people on the forums are showing negative feelings about them. I am about to get my first light and really thinking about LEDS cuz it runs cool (paranoid) and dont mind spending a bit for it. What do u guys think about these independent tests on various forms?

Hey all My mate and I are building a growbox out of a small chest of drawers, things are going real smoothly but we are a little up in the air about what lighting to use. Size etc taken into account, 2 x 65w CFLs seems like the way to go. Now we could save a wee bit of coin by just getting a red and a blue light and leaving it at that, as opposed to our initial plan which was to get two of either spectrum for veg and flower respectively. I was just wondering if leaving one of each colour for the duration of the grow would have any detrimental effects on our MJ, or would the difference be so minor that someone growing in a chest of drawers wouldn't notice/give a shit? …

Hey guys was given this old ballast by a mate today...hasnt been used for a long time and i know she is definitely 20 years old however wondering if anyone has used this Light Brigade 400W HPS ballast or knows of a reason i shouldnt use this. I know it aint as efficient as the new digitals and uses about 1 more amp in comparison but if its a good one then I might grab a cooltube and globe and give it a go. Oh another dumb question sorry..... if i were to buy a new cooltube does the lamp holder and lead/plug to the ballast come with it?? I have only bought a full kit before so have no idea? Thanks lads for any info that you may have

So i have a three speed centrifugal fan capable of: Speed 1 56l/s being 118CFM Speed 2 85l/s being 180 CFM Speed 3 112l/s being 237 CFM as well as an inline 150mm (rated at 250cfm). my room has an area of 1.6m2 and a volume of 2.88m3 the plan is as follows: C/Filter -> Ducting -> centrifugal -> ducting -> Cooltube - >ducting -> inline (should be mentioned that the cooltube has a 1000W HPS inside) All this is to occur within a 2m length (possibly 3m if i place the filter on the ground) Reasoning for two fans in such a small setup is for temperature control during the summer as even with an air con the temps can reach 30+C Thoughts on the …

hey boys hope everyone is having a good smoke..so i have a grow space of 2m high by 2.4m long by1.2m wide was thinking of putting 2x 1000 watters in there. on the cannaversity calculator it says the max should be 1860 watt with c02 being needed would it be possible to do it without the c02 ? has anyone had sucess with this type of setup? and im guessing it would have to be cooltubed ,correct?
