Are you talking about to veg or full grow? For that price you can get CFLs to veg for full grow you need to spend more. Even for that you might get one T5 that will help to veg. 3-4 plants on two 4foot T5HOs will veg for you, but you will need a lot more light to flower and 2 T5HO are a lot more than $25. I think you need to increase your budget, and if it is one of those I don't have more than $25 to spend, then don't grow. Save your money and wait a little longer until you have more than $25 to spend on lights, or grow outdoors.
