sure thing. setup is just a 30 gal trash can. pump has a 6 site manifold on it with a line to each hempy. also have a small water pump in the res which acts as a waterfall and keeps the nutes well mixed
i've had good luck with 3 nutes: DG foliage pro (although it's not the best for bloom), GH flora duo and now I'm on GH floranova bloom. i use DG pro tekt (Si) and HTH pool shock and RO water. before i leave, i try to set the pH at 5.5 and then it slowly rises. at most, it's been 6.2 after 14 days gone.
you have to play around and figure out how much water you need in the res for how long you are gone. i'm about 10 gals a week.
