Well allow me to share how I might think it will turn out if you continue your same path...

You will wind up with a few joints per plant. Thats all.

If someone were to present to me a grow like that and said, "here...you take it from here..." I would do the following:

1. Buy 6 more lights like the ones you have. (not the reflectors)
2. Place 3 lights on all her sides 45 degrees above her mid point.
3. Place a white sheet or white cardboard on the top of the carpet to aid reflection.
4. Foil wrap the pots.
5. Add white marble chips to the soil top for more reflection.
6. Make sure I gotta damn good fan blowing the heat off them.
7. Add a 100W regular light bulb on them at the top next to the CFL you have.

Now, I would do everyone of those things.......or......

1. Buy a 250W - 400W HPS....and a good fan
