When to transplant photos from Dixie cups?

If you are able to pull it out completely without breaking the soil integrity take it out of the cup and check the roots (if you have drainage holes at the bottom then just check whenever a root pops out of there), if they're at the bottom it's time to transplant! When transplant make sure to fill the pot all the way up!! more soil-more room for roots to grow-bigger plant! also try covering about third to half of the stem with the grow medium when transplanting to a bigger pot so you'll make better use of your space. Hope this helps! Girls are looking healthy, good luck and happy growing :)
