how long can plants go without water

hey, i know this is quite the subjective question dependent upon strain, nutes, lighting etc.

i have some basic nutes in the water, bc grow, floramicro and some superthrive.

i got 2 double tube 4ft floros and 2 100w daylight CFLS about 5 inches from the plants. they are roughly 3 weeks old

how long can they go without water?

Last time i watered them was wends afternoon, im home for christmas time and i was going to go up there tmmro morning and water them which would be roughly 3.5 days...am i gonna return to drooped over plants?

thanks

how often have you been watering until now? that should tell you all you need to know. not a whole lot of heat to dissipate water from your medium with that lighting. the more medium you have, the longer you can go between waterings. if you're really concerned about it, back your lights off a bit.

it depends on the system and the medium like silky says...

i have mine in hydroton - which drains pretty much instantly - i can go maybe 36 hrs before they dry up.. if you have big containers with soil that holds water well, you could go for several days or a week even.

If you're really, really concerned, set up a slow-release system with a milk jug and some rubber tubing. It'd do the job.

sounds like the damage may already be done...
