i have seen many people get 4 oz off one plant, so if you had 3 or for of these going in the right conditions I think you could. I just dont know what strain to use that will finish fast enough to produce this much.
have you seen them get that QP in 60 days from seed to harvest though? It would be possible, but you'd have to get a 1000watt HPS and id say at least 8 autoflowering plants, maybe more like 12. i wouldnt plan on getting more than 2oz each off them, even with a 1000watt hps.
Is it possible to get a pound in 60 days seed to harvest?
if you run 12/12 from seed it takes at least 3 weeks for them to go in flower, now what strain is even close to finished in 5 weeks?
