Cannabis Grow Rooms

Does anyone know what voltage (watts) and size, i.e. how many individual diodes (eg. 250?) it would take to grow two plants in a small bathroom 2.6m x 2.5m x 1.6m? Would the lack of heat effect plant growth if grown during winter temps 6c-22c ? The big plus is the ratio of blue and red light for growing and flowering, but what are the negatives, aside from cost? Thanks.

Hi everyone I'm looking to set up for my first grow. By necessity this will have to be a grow tent inside a built-in large wardrobe. I'll be placing an odoursock & extraction fan in there + an oscillating fan or two inside the tent. I'm looking at a Growlush mylar grow tent - 0.9Mx0.5Mx1.6M - so it's going to be narrow, i can't go past 50cm for the depth. My plan is most likely 2 (or 3?) feminised plants in soil watering by hand as I want to keep it as simple as possible. So, 250w or 400w HPS (or will this be overkill in such a small place ?) thanks

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 …
