There are so many ways and techniques to fit one's goals...
But the idea of not-training (maybe one topping) the plants in a s.o.g and harvesting sooner seems appealing.
That method may also be interesting to :
- try several different strains in one grow
- search for the best pheno of one strain
A friend of mine has a two level growing space. On the top shelf, vegging seedlings, clones, etc. Bottom shelf : flowering plants. The bottom is protected from light with a curtain I think. The space is limited, but he's always cloning and growing permanently. He has about 7 strains going.
Lucky you, you can legally grow a few plants...
I'm in Canada and it's legal to grow... but not in the province of Quebec; They are so incoherent. ;-(
P.s.: Growing big plants in small pots is great, but they have to be watered all the time. A SOG with different strains... may require constant attention to watering too.
