Earthtainer questions for Ray or others

[heirloomdaddy]

I am extremely impressed with the results that these bring.

I have 2 questions however:

First, I thought that tomatoes/most plants don't like 'wet feet'? Doesn't the fact that the roots are constantly saturated hinder their development/health?

Also, I would like to try some of these on top of my garage (best sunlight)

Roughly how much does a filled earthtainer w/ a couple of plants weigh??

Thanks!
