Due to certain restrictions I'm forced to do a microgrow. With the microgrow, i'm quite limited on the size of my growing medium container (pot.) I've seen several microgrows, many of them using very small containers, such as 20 oz bottles. Well, i'm fairly confident I will have to trim my roots eventually, because my containers are pretty small. How should I go about trimming roots? Can anyone offer tips? Do i need to avoid cutting the main tap root?
look for the sticky in the top of this section on bonsai mums, it will have exactly what you need to know about root pruning
