Great products
I've yet to find a box stores that carries perlite that's numbered and it's only the corset perlite that the hydro pots I also ordered needs when using them. Because of An error in filling my order, An causing extra mailing time zI was given an extra pot! Thank goodness this wasn't a plant order as it's been really to hot to order anything living.
