Lettuce production thoughts.

Thank you for your help. The suggestions and the links you provided are very useful for my project.

I was thinking about making something like this for my lettuce, to replace my current system while I am working out the bugs. I will perhaps use the current system later for some other ideas.. I am sure I can come up with some ideas for it. I was thinking about perhaps using a roofing cement similar to
Roof cement for $10
to use as the cement to put the plastic down.

I have a feeling this will be more than enough to build 2 of these systems since I am only wanting a thin layer of the cement to protect the plastic from the splinters of the wood.

On a side note.. I am considering making a small soil planter for a few lettuce to use as a comparison of growth to determine if hydroponics are growing resonably. This is more of a self note of progress/setbacks since I have no past experience with the plants I am currently growing.

Interesting, My first thought was it looks like roofing tar, and roofing tar needs to be heated before it can be applied. But it clearly says "Cold Process," so that has me wanting to look into it as well, especially if it's cheaper than the elastomeric Roof Coating.

That is my main reasoning to want to try it as well.. I have tried to work with cold tar before and it is far from fun lol.. My brother had a tree rip down the power line to his house last winter and at the probably 20 ish degrees it was outside patching the roof with tar was not very fun... A LOT worse than normal.

but a 20 dollar difference in a gallon is worth an attempt.. We will see which of us check it out first. If HD still has it next week I will be getting some for making my new lettuce system.
