  • Simple question that i cant find the answer to. I have 2 grow beds that are 11D x 24W x 72L How much viastone media do I need and what are your shipping charges
    Hello, Thank you for your question. You have a grow bed that is 11x 24 x 72. That is roughly 12 cubic feet`;` which equals about 77 dry us gallons. 77 dry gallons in about 339 dry liters so you are going to need about 7 bags of Viastone. That said it is always better to error on the side of having a bit too much, than to pay shipping twice. As far as shipping prices go it will depend on where you are and how you would like the Viastone shipped. May I recommend you call one of our well trained staff members to provide you with an exact quote or use our website to estimate the shipping costs now that you know the number of bags necessary If you need any further assistance please let me know.
