Hey man :) Yes there are disadvantages with the cooltube. The main one being that they dont have great reflectors on them as standard, they just dont spread the light far enough. If you can make a big reflector for it, like an 'adjustawing' or 'mantis' you'll get much better spread and still remain close to the plants due to the glass cover. I bought a cooltube on my first grow, just because thats all they had at the time and it is good if your using a few of them but if you have only space for one light I'd get a bigger reflector to cover a larger area :) If your growing in a cupboard where it will get quite hot them maybe you should go with the cooltube for temperature reasons :) I'm baked this morning and rambling so i will go, lol :)

Good luck with whatever you decide to go with ;)

hi man, you do have a ffew disadvantages, but not big enough to not use it if you have heat issues ^^ If you don't have problem with heat and can go without a cooltube it is not necessary. You do have a very little loss of lumens with the glass and the dust that goes on it slowly, but it's not a very very big loss. And like gonzo said the reflector they ave usually is shitty so if you can make a new one do it ^^

good luck :)

I'm going to have to agree with dust. I've used them as a normal rig before but if you have the opportunity to get a ducted hood with a wider reflector for around the same price, snatch it up!

About us

Strain Hunters is a series of documentaries aimed at informing the general public about the quest for the preservation of the cannabis plant in the form of particularly vulnerable landraces originating in the poorest areas of the planet.

Cannabis, one of the most ancient plants known to man, used in every civilisation all over the world for medicinal and recreational purposes, is facing a very real threat of extinction. One day these plants could be helpful in developing better medications for the sick and the suffering. We feel it is our duty to preserve as many cannabis landraces in our genetic database, and by breeding them into other well-studied medicinal strains for the sole purpose of scientific research.
