Hi Ethan,

You have two seeds in soil right? Well, seeds don't need light unless you are trying to keep the soil warm. Once they sprout yea, a couple small bulbs a foot away for the first couple days then a few inches away once they have a set of leaves will get them going.

When you put them under the 600 do the same thing, Start the 600w a couple feet away and move closer. The rule of thumb is, turn the light, put your hand over the top of the plant and hold it there a minute. Feel the heat? If it is uncomfortable to you it will be uncomfortable for the plant.

Here I got this for ya.
