I think they are 32 W bulbs daylight i don't worry about bloom bulbs. And it depends on how big you want them to get. One of these are going to be my mom. Whichever one looks the best. But later on i was going to give a few suggestions on dif systems you can put them into. You can go drip with a home made 5 gallon bucket drip system if you just wanted that one. You can go with rock-wool slabs with a drip system, you can go ebb n flo, bubbler, aero, or whatever you want. If ya'll have a system you want and a budget let me know and ill tell you what to get to build your system, o ya figure out how big you want the plant to get ahead of time... For example if you have a 400 W HPS you can grow 1 big plant thats bin LSTd "veged for say 1.5months", or do 4 that have each bin toped "vegged for about a month". or do like 8 that have not bin toped or tied "vegged for about 2 weeks"... There are just so many options. Do research and figure out what you want... Post any questions here. I am on 8-5 mon-fri during central time.
