That's great. I'd love to know how you go with it. What country are you in? Im in Australia so keeping water up to plants is very difficult in this climate. In a green house may be a good idea to lower the holes or leave the drainage open. If you are into gardening. You will know what is right for your environment. I've grown them in stacks. In tubes as a kid and boxes where I lay them and grow sideways. That has actually been my most successful way to grow for the most yield. But I have set this up for my mum before I go. I made other gardens here for her also that are easy to maintain and she will get plenty out of. I travel so often I do this for friends along the way and I get pics if im lucky or when I do return there is something still left. The best part is if they send me pics and it gets them into it to continue or even go further do more. I started helping a man on the other side of the country now and this is odd because he will be starting without me and I'll be going over there when I get there. No time schedule but I'm on the way. Could be like a blister and turn up after all the hard work is done.
