Hydro and holidays

I am thinking of starting a hydro setup(DWC) with clones these days. I will leave for holidays for 2 weeks. I would like to know if its possible to leave my hydro alone without getting my plants hurt. Is it better to leave them when they are in the pre-veg (and using plain water) or veg phase ?

depends on your system, for example i grow in a 5 gal bucket so once my plant gets so old it will drink the full res in about a week so i couldn't make it 2 weeks gone. I've gone on vacation for a week with it at the end of flower and was fine but if i was gone two weeks the res woulda been dry and my plants quite thirsty... Also depends on your lights, for example with cfl's you need to keep them at about 2" so by the time you get back your plant would be burnin against your light so factor that in as well.

I've never grown clones though so I can't really say what their most stable veg period is..

Overall it's not the best idea but holidays are great, enjoy

Two weeks would be risky IMO. I run 4-6 off of a 100 L Res and refill every 3-10 days depending. If just starting out in veg and everything is stable I can leave for 10 days but that's pushing it and if something went wrong.....well they would probably die lol. In the throws of flower it's replace water every 3-4 days for me.
