First cab grow C25

I don't think it would be too much work. You could have seperate veg and bloom sections to harvest twice as often. That light could do without a cool tube. You could have 2 small, or 1 bigger one blowing up from the bottom, aimed directly at the light. You would have to get that hot air out somehow, so at the top of the veg compartment could be a relatively small inline fan blowing the air out, maybe through another run of duct to where ever your other duct exhausts to.

Heres a little update. Also I have a question can I fert these things with bloom and big bud at the same time? Or do I do bloom fert and add on fert on separate days? :jointsmile:

I believe you overlap these feedings, so some will be done at the same time. Just check your PPM and make sure it doesn't go too high.

This might help, maybe not:
