If I have a 3x3x5 flowering chamber with a 400w HPS.I am planning to do 9 plants in this container sog style.What size would I need to make a vegatation chamber to hold a mother plant and about 20 clones or seedlings?I really would like to keep the mother plant as short as possible while keeping it healthy for cuttings,any input would be appreciated.Also the strand is Ice if that matters.
