you cant rush the process, and ablazed is right, how you gonna give it water without somekind of dripping system.

The most i leave my plants for is 3 days, and i flood em with water which is bad, but i also know another solution for a long period of time..

1) Put your light far away from them as possible.
2) Make holes in your pot unless it already as some.
3) Put the pot in a tray of water, with at least a few inches of water in it.
4) You can also put saran wrap over the pot so it doesnt evaporate the water as much..

thats it i guess, fairly barbarian way, but it works!
