Self Watering Planters- An Accidental Experiment
I'm growing lettuce on the conservatory windowsill, primarily for the guinea pigs. I used one planter I already had, and treated myself to a self watering planter for the rest. I'm astonished at the difference in growth. The right hand ones were behind initially, but are now producing significantly more lettuce. Does anyone have tips for buying self watering planters, or converting existing ones? I have two planters yet to be drilled for drainage holes for some of the outside veg, as well of course as plenty of drilled ones.
