I Currently have 3 CFLs on my bagseed grow as of now. I am growing a single plant that has about two to three weeks left in flowering. I've been using 3 13W 2700K CFL Bulbs surrounding the plant with one 6500K Blue bulb suspended above the plant. Im thinking about adding 2 42 W 2700K CFL bulbs to the grow because I fear the 13W are more or less useless. Should I replace 2 13 W bulbs with the 2 42 Watt 2700 K bulbs? Or should I add 2 42 Watt bulbs in addition to the original light set up? Also any feedback on the locations of the bulbs to help maximize the dispersion of the light would be great. Ohh and this is my first grow so bear with me everyone

Add it too them. Less light in veg and as much as possible in flower. Get more CFLs if you can. I would also suggest checking out the LED bulbs that are just like CFLs and maybe use those. Way more efficient if you are worried about your bill...but more is better!

I bought a couple Cree (incandescent-like shape) at Lowes. I got 100w (18w actual) because that seems to be the most efficient at 88.9 lumens per watt. (The 60w and 75w are 82 l/w and 84 l/w respectively.). I put them in clamp-on reflectors. I'm curious: Is it better to leave it in the frosted "bulb?" Does the frosting reduce the amount of light reaching the plant?

I saw floodlights at Lowes, but the efficiency didn't look as good. The same 18w flood is considered a 90w equivalent, producing 1500 lumens compared to 1600 for the 100w/18w I bought.

Compared to CFL it's a little better. 18w instead of 23w. But, not sure if that frosted bulb reduces efficiency.

@captainmorgan would know. I think there is a high risk of shock if you DO remove the glass though, I remember reading about that.
