Ah, auto flowers. What are you really sacrificing for the quick turn around, I wonder? are you going to cram more than one harvest into the outdoor season?
There is no sacrifice. If you grow them with care, you know, the proper conditions, enough light, fed properly, all that good stuff. Just like any other plant they can be potent. But it comes down to the grower to make that happen. Sure its a lower yield per plant but the quick turn around makes that irrelevant. That being said, some auto strains can produce 2 oz or more dry. Some people cant even do that with a regular plant. The more hours of light they can get the bigger they will get. Higher wattage lights help. If you check out my grows, my big devil/fast bud were in crap conditions the first two or three weeks and the fast bud still reached about 2 foot, the big devil around 16 inches or so. Then you can look at my flower power grow, and see what it is doing under much better conditions, with more light hours. Its up to the grower for a plant to be worth growing. You really havent looked at this thread, and the bud above, or the autoflower resource guide in general growing, if your asking if there is some sort of sacrifice. Do some research, Im sure you will like what you see.
