Great setup. Would a dowel-and-hub system like the old Tinkertoys work for this? You'd gain a bit more strength having them attached in a grid - and could build the grid two-boxes high for more support as the plants grew. Would be easier to store as well ... a box of hubs and a stack of flat dowels.
That's an excellent idea! I've been thinking about some type of grid system and wanted to come up with a way I could snap a bunch of hex-shaped hoops together. I was concerned about the hoops getting stuck on the plants, but a tinkertoy setup would solve that. Perhaps you'll see a redesign with your idea in the future. 👍
Thanks for sharing , I have not try doing this but is a great way to grow onions ,i sell candy onions for $ 3.oo each liks the big ones, thanks again for sharing
i would switch to something more controlling from the bottom, in a cupping shape, so as the onion gets large it pushes itself upwards at the same time getting it further frm the water but leaving the sides open to expand out as it pleases, also simpler harvestings
would adding some sealed ends to pvc piping to the underside of the rafts be able to keep the rafts afloat better with the onions so you do not need to use more of the raft material? I dont know which would last longer/cost less.

Would work well for garlic .
I look forward to your next design challenge you set yourself mate.
Keep up the great work

I thought about doing something like that but the mechanics can start to get complicated.
What about a sand bed? people on youtube have vids growing flowering plants like eggplants in sand beds.
I wonder if you could seed straight into the grow-grip
What kind of pvc and fittings do you use? Is dwv not acceptable? I'm struggling to source pvc that is not dwv.

It's possible. Each raft costs less than $10 so it might be hard to justify buying the plumbing pieces and figuring out a way to attach them.
I wonder if this would work with nft systems
I think it could work. I don't have an NFT system to try it
Could paper cups work for support? And how about economic consideration: yield x price?
is there an update on your venturi system
Still going well and we've been selling them! I just filmed a new video show a large install....it should show up this summer!
