Is this gonna work?

I designed and built this little dutch bucket system. Idea is to have a 2g/h dripper on top of each one.

It’s gonna be outdoors on a greenhouse.

27 gallon nut solution. And a water chiller since I’m in florida.

It’s for tomatoes. Each bucket is quite big, I believe 3-4g.

It’s all 3d printed in PETG and confirmed water tight.

Just wondering if there’s any obvious mistakes as I’m quite new to this.
