HoffmanHoffman 16504 Horticultural Perlite, 18 Quarts

Q: What is the particle size in this product? 1/16th, 1/8th, 1/4 inch. Is there much fine sand type "dust" in the bag when screening?

I purchased 2 of the 18 dry quart bags to add to some bales of growing mix that did not have enough perlite. This was perfect for the job. I only have a 1/2 a bag left and about 50% looks like it is an 1/8th inch and the other 50% consists of larger sizes up to about 1/4 inch or slightly larger.The bottom of the bags did not contain a huge amount of dust but it all depends on packaging and handling in the end.This is great for mixing into a growing mix, but may be a little fine to grow with this product alone. I have read a little about perlite grows but i am not sure what would be the ideal size.

Q: How course is this? I'd like to use it in a net pot for an dwc aeroponic system.

Too fine for net pots use hydroton clay pebbles.

Q: I need 100% plain perlite with no additives. Does this fit the bill?

This is exactly what your looking for. Have used in many sterile environments as well as soil additives and never had a single problem with it.
