Cannabis Grow Rooms

Ok so I'm told my small tent too small really for HPS, At 50cm X 90cm X 120cm high converted is 19sq ft Read that need 32w per square foot, not sure how correct that is. But brings me in at 600w Like to go full cycle programmable if possible. If not can use timer. Budget about 250 What can anyone recommend ? Can't really go bigger tent, no space, one plant suffice me. Cheers

Hi crew If you can control the heat of HPS (I have a 250 isomax extraction fan and 2 fans going with cool air coming from low) how far should you put a 600 hps from the canopy ? Like is it better to have it still 60-80cm from the scrogged colas or is it better to have them 20cms ? I have had them within that 300mm and had no burnt buds or leaves surprisingly but haven’t really noticed a huge difference like harder nuggets yet . I think if I keep it raised like I used to before I got the isomax then it spreads the light further across the canopy so keeping it about 40- 50cm away at the moment Just wondering if there was a preferred height or not Also I have a Dur…

I had ordered a 600w hps but it was out stock and got cancelled. This got me to thinking am I going too big when possibly a 400w would suffice . Not a huge tent,. 50x90 X 120 high Or should I stick with bigger is better, don't really see me ever upgrading to a bigger tent, I'm only a 1 or 2 "tomato" plant guy Anyone care to give me some guidance? Cheers

Howdy. Might anyone use, or have used, 315W lights with the built in ballasts, inside a grow tent? There are some great prices going for these lights at the mo, and I've been keen to have three of these set up in a 2.4 x 1.2 tent for a while. But the thought of the ballasts inside the tent does put me off...added heat and all. Would anyone here have some experience with this? Posted from the OZ Stoners mobile app

Hey crew I left my bloody 315cmh in my veg tent on with the tent unzipped last night cause the kids interrupted me in the shed so I rushed out and forgot to zip it up !!! I checked this morning , usually flower is 6am-6pm and cmh 6am-12am Should I shut off flower light for a full 24 hours just to make sure ???

Hi gang just a bit confused researching this - was hoping to find a pinned post of a previous one but no luck I’m looking at a new carbon filter and canfan fan setup for my grow room as I’ve decided to remove my tent cause I was sick to death of smacking my head on lights and snapping branches trying to get around them in late flower cycle as I had to have it in a corner restricting access.... So it’s approx 15m3 (3.8Lx1.8wx2.4 high) which calculates to 530cubic feet .... then I read you divide that number by 3 to replace air every 3 mins ? So u look for a fan which is 176cfm.... plus 20 percent for carbon filter so a fan around 200cfm .. See I’ve already confused mys…
