Thinking about the EarthTainer
I have done OK with gardening in pots over the past few years and am excited to try out EarthTainers this year to improve yield and quality. My first priority are tomatoes, but I have a number of other crops also ready to go. I have some questions/thoughts for the other enthusiasts out there, so thanks in advance for your help/info!
1) In ver 3.1 of the EarthTainer build, I like the idea of the pea fencing but I was unclear how many of the pea fences actually need to be purchased to make a single EarthTainer. Could someone please clarify? If I were to purchase from Gurneys, for example, how many items would I need (knowing that 1 item=2 sections) for each 'Tainer?
2) Has anyone integrated compost or other more natural nutrient mixtures instead of the chem fertilizers into the grow medium?
3) I don't recall any discussion about rotating the EarthTainers. In the past I have turned my pots from time to time so that the plant grows healthy on all sides. Is this necessary or feasible with the EarthTainer?
4) If I need to put the 'Tainers on a concrete slab, any thoughts about what type of insulation would be best to reduce the heat-transfer during the peak summer months? Along these lines, has anyone measured water and/or growth medium temp throughout the season?
5) Has anyone observed mineral buildup or nutrient diffusion into the water reservoir from the grow medium? (I may check this myself during the season as part of my experimentation.)
6) I believe 2 tomato plants/'Tainer are the recommendation, but what happens with more or less plants? What other crops have been tried successfully, and how do the number of plants/'Tainer change?
