This is one of the most used low cost media options. Please do a search for "scoria" or " red scoria" on the forum search, it's features, advantages/disadvantages, and safety have been discussed here at length.

Also search for vinegar test. It may save you a headache or two...

I have red lava rock in the bottom half of my beds, then river rock on top (easier to work with).

Does anyone know the weight of 1 bag of red lava rock?

Will depend on the source of the scoria and how big the average diameter is I reckon.

How big a bag?

roughly 900kg/m3 for our local stuff @20mm

http://www.lowes.com/pd/EARTHESSENTIALS ... k/50437588

0.5 ft3?

which is 0.014m3

which I have just noticed is on the bag :lol:

so would be 12.6 kg? which is close to 30lb from boss

That's close enough, figuring the strength the stand needs to be so, 30lbs X 23 bags = 720lbs ish and 12m3 media
