How long can i wait with transplanting in those sm...

I would leave them in those containers for the next little bit , A good way to tell when its time to transplant is looking at the plant and seeing how tall it is and how much foliage covers the top of the square pot . Once you see the plant it getting taller like second or third node and you're noticing the plant mass is starting to cover the whole top of your pot I would say its time to transplant . You're going to want to remember that what ever you see on the top plant wise is exactly the same amount of mass your going to see as roots and the same height as well so if your plant is 6 inches tall then the root mass is 6 inches long if its 5 inches wide on top then your root mass is 5 inches wide on the bottom in your medium . It's also really important to do the least amount of transplanting as possible to reduce the amount of stress your plant will receive from transplants . So my suggestion to you is to wait until your plant has grown a bit and gained some mass then transplant it into a 5 gallon pot or what ever the final home would be . You're in great shape . I hope this information helps you understand when to transplant your ladies as well as the importance of doing it the least amount of times as possible in order to prevent unwanted stresses -Happy Growing!
