Can an auto take 4 months to grow?

Some autos can definitely take that long. My northern lights from my last grow took 15 weeks and I ended up harvesting a little early because I needed the tent to dry another plant that was done. Just keep doing what you’re doing and be patient. Autos can definitely produce a decent yield. My first grow produced close to 6 ounces using a SCROG

I forgot to add, in future maybe try "normal" photoperiod plants, in roughly the same amount of time, you could be harvesting multiple ounces quite easily and with less electricity too. Your autos have taken just over 3 months to grow with an 18 hour light schedule and to be frank, not a huge harvest. "Normal" photoperiod plants would have taken 4-6 weeks at 18 hours then 8-10 weeks at 12 hours and given you an enormous harvest in comparison. Personally, I wish the auto craze would just go away - generally poor harvests, quite often unstable genetics, need hydro and massive lighting to perform best etc. Good luck with your future grows, whichever direction you decide to go.

I don't know why you are sorry, however, growing organically with soil (the ONLY way to grow in my opinion) won't cause any stress to your plants; they have been growing in soil since time began! The first plant looks to me about my ideal harvest maturity, but the second one needs a bit longer, maybe a week or two from what I can tell in the picture. If you prefer a more sleepy stone rather than a up and clear type of high, give the first one another week (maybe) and the second one another two to three. Leaving the plants too long past the peak THC production stage, will result in the THC breaking down into CBD and CBN, which produces a more heavy and sleepy stone and less high. This occurs because the plants metabolism has all but stopped, meaning that THC is breaking down faster than fresh THC can be "manufactured" by the plant. It is also the time when the plant is approaching death, which can lead to strange things occurring , such as growing male flowers or going into floral rejuvenation with grossly degraded THC content, as the plant then strives to have one last shot at producing seeds, to ensure a future generation of plants to continue the survival of the species. The plant has no idea it is growing in a tent and behaves as though it is outdoors and is trying to "colonise" the area where she is growing. Hope this helps,... Organoman.
