I just want to clarify something that I'm unsure of in my mind. Does the "bubble" have holes all around or just on the top? It kinda looks like all around but I can't tell for sure.

I have three Grow Boxes that I used for the first time last year, and also am building my first rain-gutter SIP. I'm sold on sub-irrigation but still don't have that "warm and fuzzy" feeling that comes with experience and success.

Hi Grant, Sorry for the delayed reply. I'm in the middle of getting organized for my move back to San Diego. It's high stress time.

I punch holes only on the top of the "bubble". It wouldn't hurt to punch them in the side but I don't think it's necessary.

Good luck with your SIP projects including the rain-gutter SIP. Bon appetit.
