Does anyone know any tips for producing around 350/400 grams per plant?

The only person I've seen do it indoors on here (I'm positive there are others) is MBlaze. I haven't seen him in a while but he grows indoor TREES!

I'll look for his thread...

Yeah ok I stand corrected. It can be done indoors. But let's look at the numbers. That latest harvest he pulled was 12pounds from 4 plants. They were started from clones, vegged for 8 weeks, and flowered for ~9 we'll say.

So in total we'll say 17 weeks of growth(ownership) on those plants. He used 4 600w.

So 12 pounds = 5448grams
With a per wattage production of 1.513g/w over 17 weeks. Not bad! But the same is possible with only a 12 week cropout cycle.

I get the feeling he does what he does because he WANTS to go big. Those numbers are still quite impressive though if you look at it in terms of maintenance per plant. It would be hard to produce the same poundage with the same minimal setup growing average sized plants. But with some more investment in equipment (for more plants), it's definitely possible to get the same payouts, more often.

My conclusion... try it out! If you got a big enough room. The disadvantage of having big plants though is well... you have big plants. And with bigger plants come bigger problems to solve. With small plants, although you are taking care of more, the payouts come more often, and you thus significantly decrease your chances of failing your whole crop.
