The CDLC is just an all around great strain. The Chem traits are very satisfying. It's a great medical as well as recreational cultivar. I've got 1 that I just transplanted as well as a Ripley's OG which is another great Indica dominant strain. That KS5000 is plenty of light for 6 autoflowers. I am on a tight budget and I've been running a Szhlux 400w Bar Style for 2 years. It's only got LM281B diodes, but, it has good light spread using 9 bars. I have regularly run 6 autos. Right now i have 6 3g pots of flowering autos plus a couple smaller pots with photo clones going under this light. You should have no problems. Just make sure you have a good fan. Good luck!
