Just A Tree - Home made air-cooled reflector - OG Save
hi, here is a pict of a easy to do modification of a normal reflector.
Since i use it, the temp is now 25°C at 25 cm of the bulb
here's the original reflector
then I just cut 2 pieces of an old reflector for closing the extremities
the hole has to be sized to connect with your extractor's air outtake
and lastly, you put a 3mm glass for closing it
Finaly, here's a plan of the whole setup.
I don't use a specific extractor for the hood, just connected my 450 m3/h extractor to the hoods, and ejecting the hot air in my living room... the smell is stopped by a carbon filter
for the one who are interested in that system, you need a carbon filter, here's what it looks like
so finaly, this system makes that you heat your flat with the heat of the lamp, and takes out most of the heat from the room, especially under the bulb, where the precious buds are...
any questions or comments are welcome

Hey thats a pretty sweet homemade light setup. +K to you. Is it possible for you to post a pic of the inside of the reflector with the light off? Im interested to see how you mounted the socket and blub inside the relector.

here you are
the air is blown through the hole on the left
another view... with a small head of a 1month old AK47/Blueberry plant quite ready for the big travel of her life to the flowering room
How is that exhaust working out for ya?? Does the heat from the flowering room still cool off the bulb in the veggin room? I just like mine but i am trying to decide if I want to use seperate fans. what are the temp in the boxes.
What bulb is it? 400W HPS?

the heat from the flowering room is cold enough to chill the bulb.
i got a 600 HPS and a 400 MH in line as shown on the plan.
Maybe a separate line that takes air outside would be a little more efficient, but this way has many interesting aspects: cheaper,silencier (no second extractor) and also it heats your flat, the air going out of the 2 bulbs is at 28°C another advantage is that you just need one passive intake from outside, and no outtake.
and in certain conditions (proximity of neighboors, copters with thermal detection etc...) that can be a very important point. the only limit to it is that you wont use CO2 in such a system, as the blower has to be turned 100% of the light cycle...
the bulb on the picture is a 400 MH.
