Unless your plants have wilted in a way that is characteristic of root rot, ... they may be ok. Sit them out of the water and see how they do.

What kind of supplies are you looking for??? Most things you can find in your own home and recycle bin. About the only thing I purchase is perlite, vermiculite and bagged soil (Miracle Grow is my personal choice) and you can get these at any big box store. Anything else???? Rosie

PS. Do what Aegis says. Good luck. If any of the leaves are still good, cut them off and start them for backup.

I would not keep them in 2" water. You should be watering then ver carefully after they dried off. The roots can get rotten easily.
