I have a few questions. My very first grow ever(including tomatoes, cucumber, etc. ) I was going to grow one plant in my closet. Space is 2X2 and about 6 ft tall. I was wondering if I could get by with only using a fan at top of closet blowing heat from light towards bottom. For lights I would...

Ok im pointing out the difference with light schedules. Major difference in growth. These are the same strains under the same lighting and conditions. Same nutes. I just wanted to point this out because everyone says GLR sucks and its not worth the time. Its not the point of it speeding up the...

So I just got my hands on a pretty decent sized unfinished cabinet but other than that, I literally have no idea what to do. I've been floating around the forums trying to pick up little bits and pieces but everyone talks about everything like pros haha so the question that lies here is: Can...

:Namaste: Would a 250watt mh and hps suffice for a 2x3x5 cabinet 2-4 plant hydro drip system

Alright, now I now this may have been discussed already somewhere on this site, but I can't find it, and it's worth mentioning again if it is. CFL bulbs and Fluorescent lighting in general is now speculated to cause specific problems in human and possibly plant species. With the majority of the...

I am about to start my first grow. I built a 6x3x6 grow box/cabinet and I need help with deciding which type of lights to use, CFL or HPS.
