Right.. I have a 12 plant limit though. I plan on getting another 400 or 2 in a couple months..
Be careful with the CMHs though....it's very easy to get too much light. √ With the perfect amount you will be very very pleased though....especially on a strain with already tight node structure....the CMH will make it ridiculous close.

Hi guys all having a good summer I hope!

@ Stumpjumper thanks man, glad you decided on the cmh. I would choose the 600w as it has the most efficient watt to lumen ratio. 12 under a 600w cmh would deliver a nice return. Just be sure to keep the plants in check as they can grow lots of leaves under cmh.

@psychild don't think a plant can receive too much light, the more light the more water/nutrients the more co2 and air the plant used and the bigger the yield. There can be however the wrong wavelength of light that can inhibit photosynthesis. UVB which is emitted in larger quantities from cmh than hps bulb is not exactly beneficial to this process. However it does help the plant with resin production. In my grow I had some bud within 5-7cm of the bulb they didn't burn and they loved all that light.
