CFL grow box comments?

So after much research and threads on here I finished my grow box and started the project. I picked up some Purple Kush and Blue dream clones (one of each) at my local dispense and set it up. Its been about a week and the clones are looking healthy and are about 7 inches tall (pics coming soon).

I have the box well ventilated with a fan that pumps air in and out through a carbon filter. For lighting I have

2 1650 lumens 5000k CFLs
2 1650 lumens 2700k CFL bulbs
1 4200 lumen 2700k bulb
for a combined total of 10800 lumens in a 2x2 area with a space blanket over the front to preserve light.

I plan adding another 10,000 lumens soon would that help?

I water them 3 oz each every two days with a small amount of grow nutrients and root booster. So what do you guys think?

If your not doing autoflower replace those 2700k bulbs and put in some 6500k.

Also dont use 5000k youll want 6500k

Will do, thanks for the comment

No prob! And hopefully you have fans to cool that box down.

Nvm on the fan part. But you need to get those lights closer like 2" away.

Just make sure it doesn't get too hot in there with all that lighting.

Thanks for the advice on the lights, also the fan has been doing a good job of keeping it cool. I check the temperature frequently with a heat sensor and it usually reads around 75 degrees. Been thinking of flowering the plants for a quick yield when they get to be about 10 inches tall but I was also thinking of flowering sooner than that. Would the yield be too low to do it any earlier?
