Interesting Stinky, thanks.

Arse. iv decided to have my lights on at night un till i get aircon.

heh, you've discovered nature's aircon. Most growers run flowering lights at night just for this reason. I sure do.

what about window units? I've seen some of the smaller ones for under $100..I'm actually considering getting one for future grows to aid in cooling and dehumidification

Should work great, provided that absent the ability to put the unit through a window or wall, you can put the 'hot' end of the a/c unit in an airmass where the warm air won't bother anything. I've seen small window units put in an attic above an op with flexi ducts, creative duct taping and inline fans used to bring cool air down to the op and return warm, moist air back up to the a/c unit. Another approach I've seen is to run the window unit within the grow room and duct outside airmass air into the 'hot end' and back out again. Allows access to the a/c unit front panel from within the grow room instead of having to go into the attic.

Swoons a great word! lol

Awwwwww thankx!

Now don't even get me started on the heat capacity of water and why a 'swamp cooler' works on the same principle... but oh so very much better!!!!

Oh fuckitall, here goes...

You can strip heat out of the air with cold water mist much better! Water has an extraordinary heat holding capacity, so if you introduce mist, allow it to heat up, and exhaust it from the room, you can strip a LOT of heat out FAST. We used to use this at a commercial greenhouse I worked at... HOWEVER your humidity goes through the fucking ROOF (duh!) and it's not practical for in-home setups or flowering plants.

Yep, stinky (and it's really hard to call someone you LIKE 'stinky' ) water evaporation is a great cooling mechanism- indeed, if you can dump the humidity... but when you do that, you dump your cool air too.

[stinkyattic]

if you can dump the humidity... but when you do that, you dump your cool air too.

Well the benefit is that you have stripped all that heat from the lights and ballasts out of your room and basically put it in portable format, lol! Like soaking up an oil spill with kitty litter... it is just SO much easier to get rid of when you concentrate all the oil (or heat) onto a carrier.

Oh... and as for the Stinky... my house stinks. It's a known fact. MY clothes probably smell like skunk too but I can't tell any more. I take it as a compliment to my ability to grow smelly houseplants.

So now that summer is here, both my fellow farmer and I have seen our temps go through the roof. We shouldn't be even trying during the summer, but we both thought, wtf, lets try anyway.

So our temps shot up to about 35C. We've both got massive fans etc, he has a cooltube, I chopped off the room halfway up with a sheet of polythylene, but we realized that the problem is that if the air going in is warm already, you're screwed.

We started philosophizing about different ways to cool things. Computer processors, motorbike motors, lots of other things are cooled by having a fan blow over cold metal.
We thought that if we could think of a construction whereby the intake has to pass over a fair sized amount of metal, it should cool it.

Then I went home. Sat there thinking that glass should be just as bad a conductor of heat as metal, so I fitted an old stormlight cooltube that I had lying around to the intake, shut the door, left it alone for 20 mins, then checked again. The temps dropped 3c.

I was really surprised at the difference it made. This idea could be developed further, I'm sure.

Thoughts?
