Almost done with planning

[Wlfwo]

I have just about got everything and am ready to start putting things together, Not sure I have enough coconut mat, is the one at the garden shop safe to use, or no? I thought I'd silicone the egg crate in. Doable, since it's holey?
Going by the number of zip ties I used to make the hanging meter box I may need to get more, although I have about 300, LOL I got them a larger wheel and plan to hang that from the back, little heathens keep knocking it over.
I got the corner shaped shower caddy and am planning that for the shell shop (then maybe they'll quit burying them). I have about 20 shells in there and can only find 7 of them. Deeper round tubs for pools.
I am going to shoot for a 2nd level in each right side corner, front one will probably be net, if I can figure that out.

Sorry nobody answered your question! If the coconut fiber mat has not been treated with any chemicals it should be fine. I always say "if in doubt, go without."
