In Reply to: Using PVC PIPE A Health Risk? posted by Chris on November 29, 2005 at 19:43:28:
: Hey guys, I am looking to get into hydroponics and was orginally going to buy a system. Once I came across this site, I saw how easy it is to make one using pvc, however I do have a concern. Does PVC have chemicals that would leach into the water and slowly over time create carcinogenic substance in the herbs/plants? I realize that we are exposed to these sorta things everyday but I dont want to build a system knowing that I might be toxifying my plants. Anyone have thoughts on this subject? Thank you.
Chris,
I would be more concerned about planting in dirt
with no pvc. Who knows what and how many carcinogens are in your dirt. Also, don't confuse pvc with the known carcinogen, pcb.
