how much is the 250w your looking at? that will require a mogul socket, which is like at least 18 bucks us. If you have to go with the 250w its not the worst thing, but i'd try to get more smaller if possible.but im pretty limited in the budget and i'd pay 7 euros for 1 45w cfl ....2euro for a socket that would be 101euro if i could veg them a bit under the bloom cfl's
im on ~200euro and got a 280euro budget o around 80 for seeds
