I need information on how to grow. I have seeds that I have collected over the years. I got two plants started but they stems isn't big enough to support anything. Plus I was told to pinch new growth to make it wide out, but instead its getting taller but very few leaves. Guys help me please. contact me with some advice. What size pot would be best to start growing in anyway? Got a grow light, have a very small size space, basically the size of the area of where an indoor ac is put in a trailer.
