My old grow tent was knackered - it was beginning to have some light leaks, knackered zippers and the final straw was the tent poles had corroded (corrosive stuff plant food run off). Rather than replace the tent I thought I would build a purpose built grow room.

I had a small available space in an out building that the Mrs uses as a utility room (where the tent used to live. I also had plenty of material kicking around from a recent loft conversion (but if I had to calculate how much it cost to build I would say less than £200 - cheaper than a decent similar sized tent).

It's fairly compact but ideal for my use - 1M wide, 1.4M long and 2.4 M high - loads of headroom, what a luxury after the old grow tent.

Knocked it up out of 3 x 2 and used foil backed plasterboard (to withstand the moisture and provide a reflective surface for the interior) and sandwiched some space blanket between the plasterboard for insulation. The floor is concrete but I have cut a pallet down to the right size to stand the pots on (again insulated it with space blanket) and fitted some casters so I can quickly slide the plants in & out for watering etc and also to give me quick access to the room.

Wired plenty of sockets (all high up) to power the lamps (a 600W Mantis HPS & a 400W MH), heater, inlet & exhaust fans, plus some spare in case I want to plug anything else in. I also plumbed in an irrigation pipe whilst I was at it in case I go away but it's not connected to anything yet.

Next to the grow room is a tumble dryer and I have vented the exhaust fan into the tumble dryer exhaust (fitted a back draft shutter of the tumble so the clothes won't smell of green in case me CF fails) and then this is vented out through the wall (if a heat signature is picked up I can explain it was the tumble - also the boiler vents out nearby so another excuse for heat) . The Mrs is so impressed with my handywork she wants me to knock up a similar structure for storage - the bonus is my structure now won't look out of place

With all lamps and fans on everything is whisper quiet.

Haven't got a grow on at the moment, so it's time for some upgrades for the grow room.

The old 5" Ruck fan never seemed to have enough grunt so I am in the process of replacing it with a high powered Vents TT125S (it's the one with twin windings so you can run it at two speeds). It can be run at high speed 370 m3/h or low speed 285 m3/h. To switch between the two speeds I have bastardised an old timer using it to pulse a relay to switch between the two windings. Assembled it looks like a thermo-nuclear device.

The next job is to line the whole room with diamond mylar -the Mrs has me lined up to do some wallpapering at the weekend, so whilst I've got all my papering gear out I think I will stick the mylar to the wall using wallpaper paste.

WOW thats a class set up brav

[Chilli]

Cheers Scotty - done some upgrades since then.

Insulated the floor with 4" of Kingspan and then added underfloor heating. Should be more efficient than the old oil filled radiator plus it frees up valuable floor space.

Both fans now installed - rubber mounted to reduce vibration for quietness. With the door closed it's almost silent (no need for a leepy box). The inlet and exhaust ducting (once out of the growroom are both wrapped together and covered in loft insulation, this an attempt to act as a heat exchanger and warm the inlet slightly and reduce the exhaust slightly (just in case of choppers).

The whole room including ceiling and door are now diamond mylar lined.

The ballast is now sited outside the growroom. For extra space and also the cooler temperatures should make it more efficient.

Just need to get a grow on.
