Just spikes I think, I dont remember. Stakes, drip irrigation stakes. It needs to not kink at the halo though or it will take up too much power. Drip holes not too big either.
Tbh those the early medidedicated days, those diy halos are no better than the ones already made. The pre made are much better and less work and cost like the same pretty much 12$.
I just stuff two 1/4” lines into a pot thats sealed up from bugs with a line splitter at each end. So 4 ports of water shooting in 4 dirrections until its rooted enough in fabric pot to just puddle up and work its way down.
