Generally I follow the seed company recommendations on flower time on first cut, with usually a couple other cuts taken 1 week apart after that. Next grow, I cut at whatever time produced the best effect on the first grow. Generally that's one to two weeks later than recommended, but not...
Too many choices makes it a tough decision. Since you're doing a semi commercial grow, I'd grab a clone from the best dispensary in your area that has a short flower time and a good yeild.
Well, the AK47 won't give you a heavy indica stone. It's a sativa dominant hybrid. Also, 400 watts is not enough light for that size grow area. Not saying it won't work, but you are not going to get great results. Optimal would be 800 to 1000 watts.
Check out "Subcools Old School Organic" (or something like that- I'm seriously baked) forum on RIU. Lots of experience growing Agent Orange there. Yeilds, phenos, etc. If you don't get your answers there, read Subcool's description. It's acurate though a wee bit fanciful.
TGA's Vortex has decent yeilds and is a very potent sativa dominant high with a true 8 weeks of 12/12 to harvest. Top it once or twice, allow for 4-5 feet of vertical growth (or SOG) and you should have no problems pulling down a pound. Odor is moderate and citrusy.
The high is a clear headed...
I have to say AK47 is excellent for pain and will not make you too braindead. It's one of my all-time favorites. It's probably not what you smoked though. With the lavender, you were probably smoking some high quality purple indica dominant strain.
I thoroughly enjoy a good Sativa or near hybrid. The ones with the worst impact on me are the strong creeper Sativas. You can get pretty far past the line before it hits you like a truck and your brain supernovas. God help you then.
I hardly ever get stomach pain, but if I did I'd vape some of my Nirvana blue mystic. Seems really good for pain, causes massive munchies, kills any nausea dead. It's very smooth, tastes good, and has a not very couchlock mellow indica high. I'm sure there are a billion other mostly indicas...
LA con just is a slow plant. You have to veg it forever to get any sort of yeild. Other than that it clones pretty easily if you're willing to wait. Not a good strain for commercial grows.
Some tough choices. I know the AK47 is trully awesome, but the TGA gear I've smoked (Vortex) is stronger with a similar high. I've always wanted to try Willy Nelson but since I haven't, I can't recommend it. In the end I picked AK47 because I know from personal experience it's good.
Breeder. You can find his products at attitude, hemp depot, speedy seedz, and probably others. I've only tried TGAs Vortex, but it's good enough so TGA will definately be in my next seed order.
Get a good portable vaporizer. It saves your lungs, reduces your cancer risk, and has almost no odor. I use an Iolite. Not as effective or fast as a bong, but much better in other ways.
It's not so much of a hyper feeling. More like it's just fun to do stuff. Your body feels good and the world is interesting, so you explore. For me, walking in the woods is an amazing experience because your muscles are relaxed and pain free and you notice aspects that you wouldn't otherwise...
