T5 light, not getting the distance right.

[Lorri D]

I have a T5 SUN BLAZE, 4ft, 4 bulb light w/ 6500k. This is the first time I am using a T5 system.
I bought this light to grow tomato seedlings, but I am growing broccoli and chard seedlings
right now.

From what I have read, I should put my plants 2 inches from the light. But, this is proving to be
too close. My seedlings are drying out and I think they might have even gotten burned a little.
But, I don't want leggy seedlings either.

If you have experience with this type of light, please advise what distance you put between
the bottom of the light and the top of the seedlings.

I and my plants will really appreciate your help : )
