Hey Kevin, thanks for stopping by.
The answer to your question is those are standard everyday cfl bulbs, you can find them at your local grocery store, also Home Depot, Lowes etc. What i looked for when i went looking for them was it kelvin light that it emites, that's the color of light that it provides. One set that i have is for the veg side that the blue spectrum, 6500k sunlight 100watt cfl, actually wattage is ranged between 23-26watt. The other i use is in the red spectrum thats the 2700k, these are 60watt on the box, 13-14watt actually. These number are actually put on the box if you look at them you can buy them from 4pk of about $10buck, to a 6pk which i've seen at $20.
I don't use paper cups, even though i can, but i was lucky enough to be browsing a nusery, and i cam across what they call seedling pots, they are about the size of your hand, and have plenty of holes on the bottom, i use those, and then pot up or as needed, surprisingly i can keep the seedling in those for about 3 nodes up, till i have to replant to the final place, veg them for a little longer in there final hole, then switch to flowering and go from there. The cool thing about those little pots, is that they are reusable.
