400 watts is a strong light. You must keep your temps between 70-85 degrees and with a 400 watt light; about 15 inches above the canopy, the whole grow.

People report a lot of trouble with the ballasts and bulbs, they order online. You have to ask yourself, this? If this doesn't work right?..whats, involved in sending it back? There are advantages to buying locally.

Something to think about....enjoy.
