I've noticed in pretty much every single thread with seedling issues, you guys are in extremely small pots. Why is this?
Within five days, my plants roots are four times as deep as the pots you are using. Just put them straight into 2 or 3 gal pots if it's an auto. Plants need to grow a taproot over the first few days. If you don't give it enough medium to grow a decent root, how do you expect it to develop?
This is 18 days old under a 100w led, had only been watered twice at 1L per watering over two and a half weeks, with no nutes and some $3 potting mix with perlite. Dropped seed in dirt, have not touched since. I think people are getting too caught up in "perfect seedling environments", but I just don't agree (and most of the pics show the proof) that a small handful of medium is enough to start a plant, and know that transplanting an auto is nit the best idea.
Why start it in something that small just to transplant it mere days after birth, especially an auto? Sometimes keeping it simple is the best bet.
