As for hydroton, I think a typical price is about $10 for 10 liters like in this link: Hydroton 10 Liter Bag. Although sometimes you will find a better prices, especially in larger quantity's.
The coco chips that I used were $9.95 for 4 cubic feet (picture attached). I'm not sure how much that breaks down to in liters. But if I remember correctly when soaked it to wash it, and it was fully expanded, it almost filled the 18 gallon storage container that I was using. There are just over 4 liters per gallon. Though the coco chips are not reusable, and the hydroton ( grow rocks) are reusable.
I don't know if shipping is a concern to you like it is to me because we don't have any hydroponic stores here in town, but I think the weight was about the same for the 10 liters of grow rocks as it is for the 4 cubic feet of coco chips. I just look at the "contact us" information on the website to see where the place is located, and I try to order from somewhere close by. |
I may give these a try. I have a small hydr setup in my house but plan a much larger scale this summer outdoors. I bought one of those portable greenhouses 7 x 12 x 7 and it will be total hydro. Just a few more weeks here in Texas and I should be able to get it started.
