it aint gonna be a strain that pulls it for you that's for sure
it's mostly about environmental conditions, most seasoned growers know that already
like smurph said, new technology.
my understanding is that DE bulbs pull 3 lbs per light even in not perfectly "dialed" rooms
CMH for veg is outstanding, i'm still not convinced that it's the right thing for bloom, but a 315w CMH draws less amps than an 8 bulb t5, and the difference in plant growth is outstanding.
I agree 100 percent. CMH for veg and flower under DE. Vegging under DE is great also. Having 10 ft ceiling was a design point for me since i built my room for an epap. Getting 10 ft is possible if your willing to work a bit. Lol allows for big plants too if that is your thing. Hehe
If i had four good plants going like a couple i had this summer i could get close to four.they would have to be good beans. PPK is good for growing big plants. Those were wide leaf dominant hybrids too so not sure i could do that with sativas or necessarily with any particular seed. Quality and potency is more important to me tho.
