Check out the above link. I have some of these for my “special” plants like the lemon tree in a pot. It has a ceramic stake and spike adaptor for the soda bottle.
It doesnt’ empty real fast, but of course my pot is only about 8 cubic feet.
Thanks so much, greeneyes! I’ll get some of these. I know the ceramic (unglazed) works. All of this years’ garden is in containers (5 gal, the big tubs, & jumbo potato bags. They were soaked & I *thought* the bottles emptied as the soil dried out, yet they were all drained within half an hour. But these will work because my mom used to use them (some like them).
I’ve been watching the radar & it’s supposedly been raining, so we’ll see. The stuff I put under the patio cover (herbs, sea grape, allamanda, & bougainvillea- oh & the strawberries), I dunno.
Thanks again! Have a great week.
