I don't see where you describe your timing. This is a light timing issue. Sounds like you started inside and moved out without balancing the light timing. You didn't put them out too early, you put them out and didn't bring them back in to harden them off and get used to "sun timing". I bet you were giving them 18 or more hrs. of light inside and them put them out at less than 12 hrs. This threw the plants into early flower. When I did this on my first grow, (and they flowered early) I was advised to dump them and start over. I waited, the early flowers didn't drop, just paused and was harvested at the normal time for some but most had to be taken early. The THC/CBD levels suffered across the board but it was good to cook with. Now, I harden off seedlings and balance light timing by weaning them off any artificial light source and leaving them outside for more and more time each day. The hardened plants then are outside 100% by one month, (third week of April). You can't beat the sun with any artificial source as long as you learn to handle the extra challenges outdoor brings, (bugs, disease, bad weather). You'll find conflicting ideas here about just about everything but one thing I've learned to share is the bigger the pot the bigger the pot! Use the biggest pot you can move around. Unless you have the right amount of space in the right amount of sun exposure during the right time of the day, you will need pots to: move into shade when it gets too hot; above 85, separate from the others for treatment, turn for different light angle exposure, move out of view angle from the nosy neighbors and finally if necessary (as it has been this year) move the whole grow inside when it got over 100 before it killed the whole crop. There is no arguing one can get more volume of finished flowers outside, but chemical strength is another discussion. With the precision indoor conditions offer I see chemical ratio's there that seem unattainable with a home grow. So I buy what I smoke and vape or bake with the home grow. Seems like a greenhouse with an opening roof would be the best bet if I was getting into the business. I'd want the superior light source of the sun in an environment where I can control temps, humidity, bugs and disease much better. Are there any commercial growers using this technique?
