I use these covers that came with an J&C Self Watering Planter. Those planters have 4 holes each (you can buy two planters in a pack). I use those planters during the winder months to stage my chilly plants before I put them in pots on the balcony. But I don’t want to further block my Click&Grow garden.
Also those planters are great if you actually buy some salad with earth on it. We have here a trio of salad that perfectly fits into the Click&Grow and J&C pots… so I can keep it watered.
Maybe it would be an idea for Click&Grow to sell similar covers themself?
