Homeade Cool tube=loss of plant light?

I hear the bread bakers(and cyclone tubes) that you can convert into a cool tube....

..are a great way too cool hot HPS bulbs. but does it take away lumen's or usable plant light due to the glass in the way? :rastasmoke:

You would lose only a nominal amount, and probably no more than a name-brand Cool Tube, or any other glass enclosure.

thanks man! have u ever made a homemade cool tube? :rastasmoke:

as gaines said, it will block a minimal amount of light, but not much more than any commercial one.

but by having the tube, your bulb can get much closer to the canopy, which provides more intensive light to the leaves.

just out of curiousity which is better in terms of cooling:

1. A cool tube (either home made or store bought.

2. An enclosed air cooled hood.

It really depends on your setup. The only real difference is that with the hood, it's (hopefully) distributing the light more evenly across your canopy.

I've tried both....cool tube can get a bit closer to your plants and has good lighting to the side of the plant depending on the reflector you use with it. . It DOES increase the heat of your growroom if you use mylar. I ended up having to paint my mylar white when I switched to a cool tube. A regular a/c hood directs the light downward as gainesville but I've also found that to help control the heat in the growroom as well. Kind of a weird paradox there.

which would you recommend? mylar or flat white? :rastasmoke:

Flat paint, always. A good, flat white paint is more reflective than mylar, easier to maintain, cheaper, longer-lasting, etc.
