i was wandering how long u guys think it would take a purple power plant (or it could be any plant i guess) to fill a 5-gallon Us bucket? they get good sun and look healthy, i just need to know so i know when to put it in the ground. I was gonna keep them in the bucket, but i heard they will still fil the bucket quickly even in a 2-3 month period. they are a few inches tall and like 2 weeks almost. how long would the roots take to get round bound the buckets. my second question is if im going to transplant from the buckets to the ground, should i wait until they are completely rootbound or could i do it anytime, what would be best? thanks alot
