Here's what you do, you forget about autos, unless you like giving seed dealers lots of money all the time, since they can't be cloned. You set up 3 flowering chambers and 1 veg chamber, the veg chamber being shorter than the flowering chambers, something like 2-3 feet. You also have a small chamber for keeping a few mother plants growing to take cuttings from. You start your clones in your cloning thing 2 weeks before the first flowering chamber is harvested, which obviously will take 10 weeks of flowering. This is a 3 week rotation system. The clones will be well rooted in 2 weeks and then you pot em up in 3-4 inch pots and put em in the 2-3 foot veg chamber, or however high a chamber you want to use but more than that is not required, under LEDs, meaning 100w replacement LED bulbs, Osram/Sylvania brand, not some shit brand. Like one bulb per square foot of veg chamber floor space. After the first 2 weeks in there you switch the timer to 12/12. That's right, you start 12/12 while the plants are still in those 3-4" pots in that veg chamber, which is actually a combination veg/1st week flowering chamber. I should point out that this system is for non-pussies, people who don't give a shit about plant limits because who the fuck follows Govt regs? You grow a bunch of small plants, not one fucking big-ass tree. So anyway, one week later you transplant them into the big pots and move em to the flowering chamber that just got harvested. That's how you get a crop every 3 weeks and the plants get a full 10 weeks of flowering. You don't harvest at 9 weeks and you damn sure don't harvest at 8 weeks or 7 weeks, because that would mean you're a fucking idiot who doesn't want full weight and potency. No offense intended, just that's what you'd be, just the way it is.
