Hello!

Alright well i've decided to experiment with growing. I want to grow one plant. It will be a northern lights x haze plant. Ok so since this has to be a super stealth operation, I will be using CFLs. What wattage would you all recomend for one plant? How many of what Watt/V?

I have a 13W 120V CFL. I oviously know thats not enough...but how many of these would I need? Just to compare.

My box it 60cmx26x26

Thanks alot!

HOW MUCH LIGHT DO I NEED TO VEG CANNABIS PROPERLY?

It all depends on what light you are using, if it’s HID, standard fluoro or compact fluoro (I assume you're not using halogens!). For HID (HPS or MH) lighting, use roughly 30w per square foot, and for flowering use around 60w per square foot. This is merely a guide, your plant, light height; reflective surfaces etc make a huge difference on these numbers. For a small plant, below 1ft tall, I’d say you would need at least 25w of fluorescent light. I find that it isn't at all practical to use tube fluoro’s for the vegetative stage past 6 inches, as only the top of the plant is receiving enough light to carry out photosynthesis properly.

Using an energy saving compact fluoro will help 'push' the light to the base of the plant, assisting photosynthesis. If the plant indicates it needs more light by growing slowly, and with small leaf petioles, you may need more light. Go with the basic rule of keeping the fluoro’s very close, and using roughly 20-30w per square foot for strong vegetative growth. If you can afford to over-light your grow room, why not? You wont regret it when your plant is bushy and healthy. If you feel that you need to only purchase a minimum amount of lights, you probably shouldn’t be growing.

Growing takes effort and money, and if you can't support a plants needs you might as well just forget growing until you can afford a proper setup. Skimping on lights is the biggest mistake a grower can make, because photosynthesis is so important to for a health plant.

Yikes, only 2 ft vertically, and under 1 foot for the length and width? It could be done, but don't expect it to have too amazing a yield. You should work your way up to like 4, 23W CFL's. I'd recommend maybe doing lst, considering you don't have much height, but I bet if you let it veg long enough to do lst, the growth spurt in flowering would be too radical for the size of the room. That 13 watt is fine for a plant in the first 1/2 weeks of life, but after that, you'll want like 2 23W's at least.

Ok thanks.

Does it matter with the warm/cool bulbs? Should I have a higher/lower K for veg/flower?
