I'm going to be starting a late grow this season with 3 plants, it's a guerilla grow and I have my spot already and what not. Only thing is there is no natural source of water for miles. I was going to do the hard work and lug in my own water, but I would like to make it not so frequent to prevent tracks, chances of being seen, ect. I'm planning on putting mulch down on the top of the soil, is there anything else I can do to spread out times between waterings? And also any good ideas for catching rain water would be helpful. Thanks.
