Also, I wouldn't worry about watering too much, 1x a day evenly watered will be fine. You can use a bigger light, but the cloner the light is, the more the plant wants to grow, and if it's focusing on growing up top rather than getting some good roots first, it'll grow funky. You can use any light, just make sure it's a couple feet away depending on how many watts, you don't want a hid light too close to seedlings, but you don't want it too far either or they'll stretch, that's why I like t5 or t8 lights because it's not alot of watts but you can put them close to avoid stretch and plants love them when they are young
