Okay, I'm done cleaning up the edges of the pipes and the Ts are an even worse fit now, but I've assembled one T as a test using a dab of glue along with the tape. The tape doesn't shred this time, but I imagine it would work better if the pipe were threaded despite the slight difference in size. I'll need to look for a "threader" piece.

The pipes I've got are an old type, according to the plumber, so next time I'll definitely do this using the current standard sizes. Doesn't feel right having to smear glue all over the place... But I decided to use what I had lying around for this project, and I'm not giving up on that yet!

Good news: All 5 seeds are in veg.

Weezard, do sativas generally respond worse to LEDs than indica's?
