i'm not too sure about using DE or floor dry solely for aeration... i know it does provide some air pockets... but nothing like the gaping caverns of lava rock, cunky perlite. it seems to me that even pumice has larger pores, more physical capabilities for providing aeration in a soil (that may become compacted over time from repeated watering) than DE. the floor dry pelets do have some more structure to them, but generally very small pores; or is there a form of DE that isn't just a dust? Are you familiar with the product I'm talking about? It's Diatomaceous Earth but not in powder form, it looks really similar to kitty litter (bentonite clay) I'm more apt to use DE as a calcium source than aeration, personally. and i wonder how much porosity/aeration that material would supply when/if the soil got really really wet (which is when you need the aeration the most, imo)
i don't think the DE/floor dry would do you any favors on the weight situation, as it also absorbs and holds water.
perlite really is great for making your soils weigh less wet or dry. lava rock is heavy stuff, so every gallon of it comes with the cost of lifting that extra weight everytime you touch a pot of soil. rice hulls are nice and light, which is a reason i use them.... i like it also because the rice hulls break down over time, giving you a lil bit of a barometer on your microbial activity and other soil borne decomposers. the sooner you need more rice hulls the more active decomposition is going on in the soil by bugs & microbes. rice hulls do not provide that large scale "cavernous" aeration like the chunky perlite and lava rock. how beneficial those larger pores are in soil.... i can't really say, i just like to have it in my mix, something larger sized with larger sized pores in my soil primarily for aeration.
rove beetles; i need to do more research about them, i suppose i could just ask all my questions here and get the answers... but im gonna do some reading first
I'm definitely getting down with some Rove Beetles this coming summer on the outdoor after hearing Heady And Seaf0ur go on about them. Do they stick around your plot or will they peace out if they feel like it though? Guess I need to read up some too
