Things are looking good, roots in aerogarden are really big and healthy. It was a good experiment to learn how to germinate, grow, top and train a plant.
The cutting has slowed growing in height buds are getting thicker. Very hairy pistils, it's a good sign.
Mostly amber hairs if you want to go by looks. I would let it go a night and Check the crystals if it's good amount cloud at weeks your at ..you will have a good smoke. Especially since it's under the sun. If you could get a bin big enough to cover it. For 24 hours dark. Just to let the crystal recover from the sun before chop.
