I’m cleaning out my tower garden this morning and showing you how easy it is to do. Also some tips for growing lettuce in the hot FL summer. Slobolt is a wonderful heirloom lettuce that is heat tolerant and slow to bolt. Grows quite large. Quite a deal too — order 3 packages of seeds from Hirts on Amazon and get free shipping: http://amzn.to/1UImhx6
Update June 2013: I now do my clean out every 2 months. I empty and refill the tower once a month. If you have any questions on how to do that, message me. Thanks!
