is the tubing safe?
7:00 pm in questions by Danielle
hey all -
So I needed to get more tubing for my window farm. I asked the hardware guy about the small script on the current tubing I am using that reads “do not use for ice makers.” He explained that there is a lubricant in the tube that will slowly leach out. He said not all tubing has this written on it, but that most plastic tubing falls into this category. He sold me a different tubing instead – but my silicone won’t adhere to it. Drats. Thoughts on this? If the water is not safe to drink then how safe is it to feed to my plants?
Cheers,
Danielle
Hmm, @gaiatechnician had another problem with tubing: http://our.windowfarms.org/2012/01/15/new-plastic-tubing-and-blockages/ Has the lubricant caused problems for him as well?
Excellent reminder to make sure the tubing you are using is FDA approved for use with food. It is harder to find cheap flexible tubing that does not leach. You might consider doing a hybrid model and using the rigid tubing from the v3 system or using low density or high density polyethylene.
