Stumbled over this today. Not something I need, but I know it comes up in discussion from time to time 20L tank, battery operated, runs for between 3 and 12 minutes a day (depending on how long you are away / how much water you want to give the plants), and 20 spikes (one per pot, but can put two in a larger / high water-demand pot) and drippers. I watched the video which seemed pretty comprehensive (apart from the American "Ounces of water per day" - I'd need to give that some deep thought!), but other than that I have no knowledge of the product £56 from here: http://www.waterirrigation.co.uk/claber-oasis-indoor-watering-kit.html
I prefer the old trusted method of getting the neighbor in under strict instructions and having toms peppers as just reward , and then a pressie when I get back. Spruce
Good plan Although I do read of plenty of cases where folk asked neighbour to do that and ... turned out that neighbour was not even competent to top up a header tank!!
" If I lived on the South Wales coast I wouldn't bother going on holiday, it's one of our favourite parts of the world, next to Yorkshire of course We will be back down there in about three weeks. Quick edit to conform with the thread, my next door neighbour will be looking after our garden and just in-case he reads this "and very competent he is too!!"
