inidcas are good for sog depending on the strain, some are more bushy then others. You could scrog them if you wanted but i personally feel like training them works just as well. I do a perpetual harvest but i have a whole room dedicated to flowering, i keep 16 in flower at all times and chop 4 every 2 weeks and i never run out of bud for myself or the few customers i deal with. I grow enough to smoke for free and offset the price of my electric bill and the money put in the grow for soil, nutes, and whatever else i use. If you can then thats the way to go because the first time i grew i realized how much it sucked after my harvest when i had to wait for drying and curing and then running out before the next plants were done. Its an amazing feeling to know you always have some clones rooting, a wonderful mother plant with the others vegging and a whole room of floweing beauties with a closet full of hanging buds and a cabinet full of mason jars curing to perfection.
