100 GPH is about right. We have six plants and found that the Ecoplus 396 GPH pump did not have enough power. We now use an Ecoplus 633 GPH pump and it works well. We made a manifold of 1/2” Rainbird valves and set them all to about 50% open. A lot of attention into making things as equal as possible, like making all tubes the same length. It is fast. Our system takes about 1 minute to deliver nearly 2 gallons, so we use a timer that lets you set seconds.

can a person gravity feed and use the ring to water

Yeah, shouldn't be a problem. 1/2 feed tube goes to about 50 holes @ 35 micron. Get a 100-150 micron sediment filter if you are going to be gravity feeding. I used a 1500 gph fountain pump that turned on every 4 hours just to re-initiate a vacuum feed. You could probably get away with half that power. I had six buckets on mine.

I have 1/4" drip line tubing - how would I connect the tubing to your product? Do you have any reccomendations?

I used 3 1" cuts of different-sized clear vinyl tubing to step down - where the largest fits the 1/2" barb on the Halo, next smaller size fits inside the first piece on the barb; next smaller size inside that, and my 1/4" drip line fits inside that. I'm a home brewer and already had spare tubing/hoses. There's no pressure in mine as I gravity feed from a reservoir above the halo/plant and the 1/4" drip hose simply twists out to move the plant.

Whats the difference between the new version and old version?

There hasn't been any changes made to this product, we recommend contacting the seller for additional info.
