I have been growing four church plants in a small grow-box. They are growing very well and are just starting to produce the fourth set of branches. However, I have noticed very small root growth coming from the bottom of the pot. I am worried about them becoming root-bound. I have been using seaweed extract which is meant to boost root growth but i think it may have worked to well. They are in 1L herb pots at the moment. However the weather isn't really that great to be putting them outside yet and I don't want to be moving them from one pot to another then to the ground. (Hermie's :\) Does anyone have any ideas? I have heard of soaking the rootball in a seaweed extract solution but im not sure how to do this? Thanks Tom Also what do people do when transplanting from pot to ground?
