Outdoor grower finally coming indoors. I am building a grow room and and I need those questions answered.

I plan to have ~3 month cycles and I will be using a bubble bucket system that uses 5 gallon reserviors...

So for this, how many plant locations and how big of a room would some of you recommend? I am looking to have as many plants as possible but want to get at least 4 feet tall. Also please unclude what you expect me to yield each cycle.

Thank you

I've never used Cfl's for flower, only for veg. But those bulbs probably put out around 8000 lumens per bulb if they're like most. Correct me if I'm wrong, but it should be around there. You want no less than 5000w per sq ft for a general rule of thumb. But those bulbs will also diminish in intensity very quickly. So the further the light travels, the light decreases drastically. Especially compared to HID lights. If it were me I'd grow 1 plant with all 4 lights hanging vertically around the plant towards the top of the canopy.

Theres no way those lights will penetrate anywhere close to a 4 ft canopy of multiple plants. That's why I suggest 1 plant with those bulbs surrounding the plant. Again I haven't flowered with Cfl's but I know if you try to grow large plants with them, you'll get airy buds and a lot of popcorn. Either once plant. Or say 6 clones with 0 veg time.
