Its best to take a look at my video and you can see how i installed it and how it works... on my third video next week will go into further detail on my setup for people who want something setup like mine...Sounds good, I already got myself a 6 inch cool-tube, its not really big enough for the big fat MH bulbs, theres still room for some air to squeeze past the bulb but it would be better to use an 8 inch. I guess I will make it work.
You say you can touch your tube without burning your hand? I haven't got my tube fully rigged yet, nothings really finished being set up in my room, but working on it. Anyways I run a fan over the plants and it also pushes just enough air through the tube to keep the wires on the mogul from melting(they actually melted a bit from the heat when I moved the fan for a few minutes lol).
So how many CFM do you pull through your tube and how big are your lights? I'll check out your thread in a minute just thought it would be easier to ask. I intend to have 3000 watts burning in cooltubes, with 1 fan to cool them, How many CFM do you expect I will need to pull through the tubes to do that? I have a 4 inch fan that moves 175 cfm, I am thinking its not going to be enough? I will also be cooling the room down with an 8 inch fan on a carbon filter. Can I even use a 6 inch fan with the MH bulbs?
Ill bring a picture up tommorrow when the lights are on again
its just a basic 6'' can fan i got with my cooltube at my local hydro store, your wires melted?.. which way was the air blowing.. it should be blowing air from the side the bulb connects to its socket in the opposite direction so the hot air doesnt go over your wires but only your bulb.. get me?.. watch my video..
and im running a 400 watt mh on mine, and will swap it over to a 600HPS during flower.
and remember 'EACH COOLTUBE NEEDS ITS OWN FAN'
You want 3 cooltubes?.. you need 3 fans, one for each... and remember.. each bend you do in your ducting slows down the airflow because of 'resistance'.. like car exhausts etc.. the straighter the piping.. the easier the flow.
If.. you went ahead and got 3 tubes with one fan,, after the air passes over one bulb it gets hot,, then moves over to the other bulb and gets hotter.. etc..
your supposed to move cool air through not hot air.. thats the idea of keeping them cool..
and make sure all that heat is being led outside the house...
tell you what.. ill make a video for you tonight ! sneak peak ! and go into detail about my setup BUT ONLY IF YOU SAY PLEASE lol.. i did alot of research and reading before i commited to my setup.
