customdrum those bulbs won't fit in his hood because they only fit those tube shaped bulbs. But yeah I use those same bulbs you have pictured also, all in different watts too. But you have to modify some hoods for it. the ones tigerbarb are talking about are the ones pictured I think. I have some of those in use also.
2 bulbs should be fine. depending on the plants and your lighting schedule
Haha yeah! those are the ones!
