lovedovegeneration Posted November 7, 2019 Share Posted November 7, 2019 Afternoon, first post – Hi all. So the story so far, my mate rang me and said would I help him set up a grow tent, neither of us had a clue where to start so I’ve 3 months reading up and buying stuff. I’ve kind of taken over the process and after much research I convinced him to do a loft build. I started 2 days ago and I'm about 7hrs in so far - Brief spec is: 1.2x.2.3x1.8 high Wooden frame with sloping roof 50mm kinspan/celo/etc with another 25mm spaced away from the 50mm to create a thermal gap (not sure if needed) B&Q silver bubble wrap outside and in. Two 600w Fan cooled hoods Dimmable ballasts x8 15L Autopot system Air pump for res Contractor light timer Ecotechnics controller Carboair 10" 1metre filter 6" RVK 8" RVK I’ll get some pics uploaded when I get back to his – ‘working from home’ tomorrow so should be able to crack on again. 4 Link to comment Share on other sites More sharing options...
lovedovegeneration Posted November 14, 2019 Author Share Posted November 14, 2019 Roof is on ! I had to build the roof and then lift it up at each end onto the 4 uprights, took some doing on my own ! decided against the air cooled hoods and went for run of the mill, which I'm thinking was a bad idea as the heat could have been used to heat the room, but was concerned with noise. Just waiting on the pond liner and MH bulbs now and then I can finish the build next week. 6 Link to comment Share on other sites More sharing options...
tokenroll Posted November 14, 2019 Share Posted November 14, 2019 Looking good and a nice size. Make sure and run some aluminium tape along all the joins of the celotex. 2 Link to comment Share on other sites More sharing options...

I've also butted all the joints together with dryfix foam. Temps concern me as we have no way to pull in warm air as he does not want to leave the door open to the loft, I'm thinking of building some kind of hood to go over the ballasts and using the heat off them, not sure how hot they get though. I've got a temp and humidity data logger so I'll soon see if there's an issue with temps. Link to comment Share on other sites More sharing options...
M Pamplemousse Posted November 15, 2019 Share Posted November 15, 2019 Can you draw warmer air in from the house. You can then heat this using a radiator in a box if necessary. I have just done this and now have useable temps. 1 Link to comment Share on other sites More sharing options...

Yeah maybe, he wants to keep the door shut that leads to the loft stairs, he has his kids at the weekends and wanted to keep the door shut if poss. It may well be warmer at the bottom of the stairs so we may be able to get away with keeping the door closed, or just tweak it so it has a gap.

joe9000 Posted November 15, 2019 Share Posted November 15, 2019 (edited) Draw warmer air from cutting a hole in bedroom cupboard ceiling. Edited November 15, 2019 by joe9000 1 Link to comment Share on other sites More sharing options...
botanics Posted November 15, 2019 Share Posted November 15, 2019 That's what I used to do when I was in the loft...no major expense on heating the air going in then come winter time as it just needs a top up as opposed to heating freezing cold air from outside. Build looks good Link to comment Share on other sites More sharing options...

His loft is bigger but I expect it to be just as hot/cold. In summer I have flu I can pull cold air from so should be fine....I hope. Should be finished next week, I've managed to blag 3 days working from home, which is more than enough time to get it completed. 1 Link to comment Share on other sites More sharing options...

lovedovegeneration Posted November 22, 2019 Author Share Posted November 22, 2019 Santa's grotto is finished ! I think I may have gone overboard with the filter, I was hoping to run it along side the lights but it's far to big ! so it's going along the back wall and the fan will have to be outside the grotto. Fitted a pond liner, rubber mats and some floor files on top of the mats that I had kicking about to try and keep the cold away, all lined out in white - been a long 4 days, I need to be back in the office for a rest. 9 Link to comment Share on other sites More sharing options...

Ned Flanders Posted December 13, 2019 Share Posted December 13, 2019 Don't forget fire safety. Smoke alarms inside and outside the groom and an auto powder fire extinguisher to hang above the lights. Make sure you can detect smoke in the flu. 1 Link to comment Share on other sites More sharing options...
