Capillary-fed tank system in Mays magazine
Have just read the May edition of the magazine and noticed the article on page 79 regarding the step by step guide on watering your greenhosue when away.
Would a tank the size shown really last 2 weeks with 4 tom plants on top?
Also, where is this one picture availble to buy, a website would be most useful as doing a generic search doesn't find it.
I wonder if its possible to make you own out of some dark storage vessels of some kind?
