| Have you had any experience with using these water filled tubes to plant tomatoes 30 to 60 days before last frost date? |
| I've used them about 30 days before, but not 60. They protected the plants and helped get a jumpstart on the season. Sunlight warms the water in the cyclinders and the heat is released during the night. I would think that if the plant is actively growing, it would outgrow the size of the Wall 'O Water in about 4 weeks or so, and would require another form of protection from frost. |
