good day man, how do.... i don't think it would work with just the neoprean till the end, the plants get too heavey..... what i do is just change the neoprean for a bigger one and then hang it in a plastic net pot, the roots go through the pot and create a stable base for the plant... you can even just get the small net pots and use them.
hope that helps ya some....
