TLDR - you shouldn鈥檛 buy for a very simple reason : pipe tips fall appart due to water pressure.
I鈥檝e spent a whole week-end preparing my setup since we were leaving our house for 2 months. When I came back, half my plants were dead since a few connections collapsed with regular water pressure.
Assembling connections was a nightmare. I鈥檝e even added mini-tie wraps to solidify these loose connections but even then, it all fell apart.
Other similar packages/resellers will have the same problem. The technology itself is the problem. Do not waste your time.
Update - multiple friends of mine faced the same issues making the system inoperable.
