dude that blows, if your gone for two weeks you better set up some sort of creative drip sytem, or get one of those wierd aqua globe things..
Not sure how it will work but def better then dry for two weeks..
I would give your plant a good dose, overdose a lil bit of nutrients a few days before you leave (just enought time to let the soil dry out) Then the day you leave set up that drip system..
Your going to come back to a very droopy plant, know this... it will be a sad sight..
But invest 15 bucks and buy some superthrive and give it a good watering with 1tbls of molasses per gallon of water, the recomended amount of superthrive and 1/2 the recomended amount of nutes and your plant should be ok and doin good in the following day or two..
Also if you add like 3 more lights when you get back your plant will RESPOND AND COME BACK!
Good luck with that tho,
dont chop it, you can do this, deep breath now lol
HOpe that helps
