[However I am in the process of changing over to 1/2 drip line. I no longer feel comfortable with using PVC exposed for long periods of time to heat and sun. It may be safe but for now I am switching to polyethylene drip line.

I see more advantages than disadvantages. Polyethylene drip line is cheaper than PVC. 500 feet of 1/2 inch drip line is about $100. 500 feet of 3/4 PVC is a little more $ but a lot more $ if I have to use 1 inch pipe. I can use much longer runs and water a larger garden all at once. I feel more confident that polyethylene is a safer plastic for the garden]

I never thought about the toxic effects of pvc exposed to sunlight. I had planned on burying or covering with black plastic mulch.

The 1/2 poly tube is a tad more expensive but perhaps worth it for ease of use etc.
