use the t5s then the 250w dual spectrum hps bulb to flower and veg the whole way through life from a seed to the time the little angel sprouts and pokes her little green wings up through the soil, i use t5s and 600w, the only problem with this is a constant 18 hour a day power supply and the heat generated too, i dont know where you live but there is a 250w dual spectrum bulb on ebay uk cheap item no. 280649991410, this gives you an idea that you can get cheaper equipment, some guy/lass in here pays just under $250 now for the hard part the heat, i am assuming that this is a sealed cupboard, if your pretty skint cover the walls in a cheap whitewash flat paint to reflect as much light as possible and bore a hole in the door and istall an outlet fan on the top of your cupboard door 2 decent pc ones or a bathroom fan will do to suck out the hot air the problem with pc fans is they are low voltage, and fans can be noisy, if you bore a hole a little larger at the bottom and leave it sucking in when your fan is on this is your passive cold air intake supply, when the room starts to go in to negative pressure the fan has to suck air from somewhere, if you build a small shelf just below your exhaust fan you can set a jar of ona block fresh linen ebay number 280649199284 when the hot expelled air passes over the block before it leaves your small room this will deoderize any smell and you can get a couple of plants in there when you have finshed growing in your room you can repair your door by covering in a 6mm plywood skin measure your door and the guy at the timber merchant will cut it free to the exact size and you can panel pin it on and paint it to hide the earlier damage.

Well right now I have a nice steady air flow with 3-6 inch fans. One blowing air up , the other blowing air to the top of plant in between plant and light and other light blowing air out my closet. I have a steady 80 degrees. I was using 1 oscillating fan when it was in veg but i couldn't get the temp down, it would always stay at 90-95. I'm really happy with this 250 watt Hortilux Super HPS, I see a gigantic difference already in the plant and Its amazing! Before I germinate my next seed im going to buy a 250 watt Hortilux Blue HPS. I really am grateful for everyone's great advice on a HPS system!!!!!!
