I decided to direct seed in the GT2 this Spring (more like summer, already 90+F) And with the constant strong Vegas wind, sometimes blowing all day long, after the seeds were sown, I decided to give the Tower some protection. I wrapped up the top and the next two rings with clear plastic wraps, leaving little openings for air circulation, and then for the lower rings I cut up some used plastic water bottles in half and put them inside the openings, securing each with a bamboo skewer by poking holes in them. This way, even with the wind blowing, the skewer kept the half bottles in place. If the pockets got dried up, I will just mist them with a sprayer. The plastics and plastic bottles should keep the seeds moist until they germinate and protected from the wind. We’ll see what happens in a few days. I also replanted the old lettuce and marigold seedlings, and keeping my fingers crossed that the new revitalized potting mix will do well, even with left over thin roots in them.
