Generally they say 100 watts per plant but ill tell you first hand (only on first grow) that the more the better put ALL you can on that plant. Iv upgraded bc im poor throughout the grow from 80 watts in beginning to now 230 watts each 20 - 40 watt increase I could visably see the difference in responded growth compared to its growth rates b4. more light more energy for the leaf to absorb and turn into energy you really cant overlight a plant. Also you will want to use 67k spectrum (blue light) CFL and the 27k (yellower light) during the 12/12 flower stage where light is even more important than before because this will be the factor of how dense and potent and how much you harvest. Iv seen countless posts saying witch lighting from dfl at flower for intensity but I wont be able 2 just 26k spec CFL at 300 watts is my goal.

Its ok, you will get something, but honestly with 80w don't expext for than 5-10, maybe 15 grams from one plant. And thats after 3-4 months my friend.

Are you growing from seed? Cause its going to take about that time no matter how much light you use. Even if you start 12-12 from seed, it"ll take 3-5 weeks to begin flowering and 8-12 weeks to finish. That's about 14 weeks brah, or 3.3months
Pot is "expensive" for a reason, people put a lot of time and effort into this stuff.

CJ1200: I use (4) 23w CFL's {6500k veg. + 2700k flower} per plant in a 4'x2'x3 1/2' pro-gro tent with Humbolt Nutes and FFOF soil in 3 gal. Smart Pots and I avg. 1 1/2- 2oz. per plant {6 plants per cycl evey2 1/4 months. CFL's aren't ideal but will an do give results. The more light, the better the results and bountiful the yield.

Those 40 watt lights have about 8 inches of penetration for flowering, keep that in mind. If you use no reflector you will lose over half your light too. The light comes straight out the bottom and straight out the sides of the bulb in a circle, like the spokes of a wheel.
I use a large 11 inch diameter clamp reflector with a y splitter for the 2 bulbs. It doubles the lumens or intensity of light to the plant. You will need a small fan to cool the top of the plant as the reflector traps heat, I do not use one but if you want max yields you will use one.
With the 40 watt bulbs you will need the y splitter and an extender which will run you 3 or 4 bucks. Without the extender you will not have room and the bulbs will hit the reflector. I use 27 watt bulbs so only need the splitter. Hardware store will carry this stuff but a large reflector is not going to be in every store.
The 2 bulbs together in the y configuration will mix the side light from each and give you additional penetration, like 16 inches if you are lucky. You can grow a 1 oz. plant with this setup. If the bulbs stick out of the edges of the reflector a bit, which I think they will, you can use chopped up soda cans or other aluminum to glue on the edges of reflector and extend it 2 inches to get all the light reflected.
Keep the plant as close to the light as possible without burning it. At first a few inches away and in 1 or 2 weeks drop that light within 1 or 2 inches from the plant. You can adjust as needed, farther away for stretch, closer for keeping it short. In flower you want it close for sure. 2 gallons of potting soil should be enough for a plant.
If I were you you I would think of doubling your light setup as I described above, and grow 2 plants. It takes me 4 months from seed to cured buds. I veg for 6 weeks and then flower for 70 days. The longer you veg the more you get later. Cure is a week minimum to smoke, and a month to have really good stuff.
