How do I grow single cola plants? Do I have to strip off everything from the stem and just have the main top growing (like a stick with leaves on the top) or do I just keep the brantches small so there is room to grow bud down the stalk. I see pics of single cola plants and there is bud all the way up and down. I don't see how it got like this is you have to take all the nodes off? Thanks a lot. If you are confused I can get a pic to explain.
