need veg box quick!

Well, i ill-prepared for the end of my run and now am trying to quickly sprout mothers...well the problem is, my seeds popped a little TOO quickly. So now i need a veg box, and fast...like tomorrow morning. i want to make it out of a rubbermaid tub, this will be veg only, so will a 1.5 or 2 foot fluoro be sufficient? will there be any heat problems if the light is directly attached to the top of the tub? if i cant find small net pots, what is another good solution? im thinking 2 1-gallon buckets inside a rubbermaid, DWC system.
