I don't think plants want to live off of r/o water.. i think they may need some minerals in the water. not sure though because I don't grow pot, er, um,... plants and flowers and such. just a thought though. if you really want to use r/o water, why not just run a longer tube up to your room? the r/o faucet would not be able to make a lot of pressure before it shut off and went down the drain as waste water. the r/o system should be able to pump about 25 feet of 1/4" tube, so just run a line to where you want it and then use a shutoff at that point. easy peasy.
