Look for the new filter socks that just came out. I'm testing one out- you can even throw them in the wash, lol. And inexpensive. For a small med grow, you may not need anything larger!

This is cool, funky Matt and his funky plants. We'll be nice to your pops- he should register himself, like PapaFunk or something so we know who he is.

I don't like mylar for anything larger than a microgrow. Look into Panda Film instead. It is a far superior product for most uses- it's more durable, lightproof, and doesn't lose its reflectivity when dirty like mylar.

For antianxiety plants to put in there, see if you can find a strain called Black Indica. It's veeeery mellowing.
