Thats allot of light for a lil one. for one seedling you dont need anything other than a 23w CFL daylight bulb, if more than 1 seedling you might need a couple. I use a real smal 2 bulb T5 I picked up from Home dePOT.
The Walmart near me had them cups in Halloween colors (black & orange) and now are back to red and green atm lol.
