Default Is the home depot vermiculite good?

Hi, I'm searching were to find the vermiculite here in FL, and I want to know if the vermiculite from Home Depot is good, and how much do I need for a 42'' heart.
Thanks.

I just went to an independent plant nursery and I found big bags of vermiculite $25 and perlite $18, I bought one of each.
I will probably mix them and do 5:5:2 for the heart.
Do I get better insulation doing that?

Check with a concrete block supplier. The HD price is twice as much for half as much for what I paid at a concrete block supplier. 4 cu ft for 10 bucks earlier this summer.

Keep in mind that if you buy block fill insulation it will be very fine. Agricultural supply and building yards carry the course vermiculite...it will have better insulation properties.

I found that the Home Depot vermiculite was too fine. I went to a different hardware store here in Northern California (Friedman Brothers) and found a supply of larger bags with vermiculite that was coarser grained - I as much happier with this

I just received my shipment from Uline I purchased the grade 4 stuff. I think it was $34 dollars for 4 Cubic foot bag, I bought 3 bags. Shipping was pricey I thought. I ordered it on Saturday and had by Tuesday.

That is pretty high. Had you checked with agricultural suppliers for perlite or vermiculite?

Mine was 22$ for vermiculite and 18$ for perlite in 4cu.ft. bags from a nursery....and I may add it was the only thing that was easy to get where I live.....

So if I do a 50/50 mix for the heart, how many parts should I use?
5:5:2 ?
I've been reading how to built it but, I'm a little bit confused, should I use portland cement or regular concrete?
Thanks.
