Rite lol,,,,,,, my mum has handed me the shed to do what i want ..

Im wundering about venting.


My BRICK shed is not insulated and is about 8ft x 6 ft, n 9 ft tall. I live in the UK so it rarely gets hot. im only going to be using 1 600w for about 5 plants so ill only be using a small amount of room in the shed.

can i just get a normal fan that keeps air circulation going because as far as i can see, the heat from the HPS will be quickly lost as it diffuses into the large area. annd b4 it has chance to build up it will be lost through the walls...................... and thoughts???????


and how many plants would i be able to get with the 600w thanks in advance :

Are there any windows in this shed? Any type of insulation? If not you could think about adding some type of water drums that would absorb the heat put off by the lamp during the lights on period and then emit it at night.

No, there are no windows in my shed

... but there is no insulation either

Just 1 brick thick... so heat shud be lost easy enough right????

Think of this as adding passive solar to your shed. The barrels of water would absorb heat during the day or hours when your light was on. During the night or when your light was off the barrels would release that heat back into the room. At least in theory that works. I don't know how warm of cool your room gets. But that is the bare bones of passive solar.

Thanks mogie +rep

YOU will still need fresh air to come in and old staleair to go out dead stale air can cause many issues so venting is for more then heat its for the plants survival it needs new air brought in.

If you have a fan pulling out the stale air there should be enough cracks that fresh air will be drawn in. Just need to come up with a good exhaust fan.

ya see thas my problem. i dont realli wanna go cutting big holes outta the shed ...


................there is however a small 15cm x 30 cm vent made of brick (the sort of thing you have at the top of every room in oure house...look around u will see one right now lol )... i suppose i could force the air through that... the problem is that there isnt THAT much room for alot of air to escape............

Well you have to get that old/stale air out. If that is the only way then that is what we have to work with. Can you slightly enlarge that opening? Say to 4 square inches? I understand you don't want to cut holes but if it's enlarge on hole that is already and this would be soooooo handy.

stay online lol.... ill try and get a pic of something simalar off the internet m8
