Drip to Aeroponics conversion advice.

Would there be any draw back for converting my drip system to an aeroponic setup? I could plug the drain holes in the bottom, and stick an air pump in there. I'm having issues with my rock wool drying up fast, and after watching the Sea of Green Hydroponics video, I like the way that setup works a little better. I figure with the drain holes, it will make emptying and refilling a cinch.


Any advice would be appreciated. I will have a 400W MH and a 125W fluorescent in a 3x3 tent.


Thanks

I'm not liking the drip system because my spikes don't stay in right, and end up knocking my plants over if I try to use it on a timer.
