Warm white is better for flower than veg. They will work. I pop off the safety glass on the Cree LED I use in my veg cab.

As you how many - as many as you can!

yes you can use LED bulbs to grow, but be careful with that flood light style as they can create hot spots which can burn your plants , so you cannot keep them close like you would a CFL

Yes ! marijuana can grow in just about any type of lighting - but when you get specific that is when you achieve good results

You need at least 5000 lumens to grow. 880 is almost nothing!
For veg you need 5000K-6500K (Daylight/Full Spectrum). 2700K (Warm White) is for flowering.

the OP said he has 20 bulbs, so that's 20 x 880 = 17,600 lumens

5000k-6500k is optimum for veg but you can veg with 2700k, just won't get as good of results

if the OP were to add a few 6500k CFL bulbs, it would help the spectrum

I don't bother myself to run twenty 11W 2700K LED bulb in a messed up fixture for veg (which is a lose-lose), when I can sell them and get some CFL instead!
