1st CFL Grow - White Widow in the
Indoor Growing forums; Hey guys!
First of all nice forum you've got here! I am very much interested on your feedback on both ...

Lights: I have found that the more light I am able to utilize during a grow directly increases the density of the flowers on the plant.
Flowering: My plants usually double in height after flowering is induced. That being said sometimes they don't get that big and occasionally the get bigger. Indica leaves are fat and sativa leaves are longer and thinner.
Clones: I cut my clones from the lower branches that you would normally lollipop off in an indoor grow. I cut clones before flowering is induced but I have seen people do it after.
Yield: I average about an ounce to an ounce and a half per plant under a 250 watt hps. Production can be further increased by manipulating the amount of flower sites through topping, fimming, etc. And of course, by adding more light.
Your box is about the same size as one of my older rotating or flip-flop twin bloom chamber perpetual harvest micro stealth system I used years ago. If you're gonna' stay with the CFLs, go all out with some 55w (200w equivalent) high lumen output bulbs. In earlier seedling and veg stages the amount of light is not as important. But when you switch to 12/12 to begin blooming, much more light is needed to get professional results that won't disapoint. I'm still partial to my old 150w HPS lights for that type of set up. I used 2x 150 bulbs in a 17" sq box for blindingly bright lumen output. Two Hindu Kush plants would pump out about a QP (4 oz.) every month is that tiny space. My units were about 6ft tall though, and I'd induce 12/12 when they were about 18+" tall, or 2 mos. from taking clones (including 2 weeks to root). The taller the plants are, the proportionately bigger the yield. I didn't top the Kush at all and relied on mostly the two monster top colas developing a consistently potent harvest overall. Granted the 150's generate more heat that can pose a problem. But in a small box you want a good rate of air exchange (via a 12v PC fan) when the plant get bigger anyway. In the end the whole idea is to replicate super bright sunlight outdoors over the course of an ideal So. Cal. summer season- all year long.
A little trick I use to increase yield requires a little more effort and attention but is worth it when usable space is limited. I transition from 18/6 to 12/12 over a two week period that more closely replicates the natural seasonal shortening of daylight outdoors. Switching to 16/8 for a week, then 14/10 for another week. Then 12/12 at the end of the second week. This way the plant more gradually enters the blooming stage. The end result is buds are far longer and thicker overall than going abruptly with 12/12. And this is why outdoor plants invariably develop longer and phatter top colas and overall yields outdoors relative to plant size.
The first thing I can say is get more light. Add the beg bulbs to the flower if you have to. Also, if your soil isn't really potent, get some nutes. Miracle grow if you have to! Take clones before flowering. Allow the plant to get over that shock.
