Net Cups

They are the perfect size for aquatic plants. The quality is great! Super easy to use. They are exactly what I needed when looking for aquatic plant maintenance.

Small hydroponic net cups. They fit about a 1” rock wool cube. Extremely sturdy. The sides and bottom have large openings which make it easy to remove a plant without damaging it. They are small, so they are mainly good for small plants, starting a plant to transfer to a larger container or rooting a cutting. They are very inexpensive and will last through multiple uses.

Time will tell how these hold up

I'll take partial blame for not reviewing their pic better, but I would think a net cup advertised as a 1" net cup should fit a 1" hole. The cup will only fit up to the red arrow on the pic I've included. It does however recommend a 32mm hole (1.2598".) I mistakenly thought that since the top inner circle was 31mm (1.22") it would just stick up a little bit.

Finally, a net cup that actually fits my cloner slots!I prefer to germinate my plants in my aero cloners to minimize mold, rot, neck collar pucks, and transfer time.I’ve been using tapered 2” net cups that only fit half way in my cloner slots, which requires spacing every other site and covering the slots in between with the foam pucks. It is always a pain and inevitably leaks water.These fit perfectly in all of my aero cloners so every site can be filled.Only complaint is that they are translucent.I wish they came in solid black or white so there would be no light penetration to encourage algae growth.White would be preferable to mitigate heat, but I’ve already ordered another set of these, so it’s clearly not a deal breaker.

These arrived exactly as the picture and product describe. They are great for creating plant plugs or trying to root cuttings/propagate plants. They are very small so plan accordingly, but they were exactly the size I wanted

Works okay.

If you grow in Oasis, Rockwool or Rapid Rooters, these cubes best fit the small 3/4 inch Oasis cubes with a matching square shape unlike most other round grow baskets. No need to add filler material, the cube completely fills up basket. Quality is nice, very sturdy and well designed large vent holes for roots, easy to clean. I wish they were completely opaque or black. They are frosted translucent. Not an issue in my case since they are submerged and fill a tight hole, but something to take note if your system exposes them to light and could allow algae to grow. Small con to otherwise perfect little pots.

Used a spade blade which don't come any larger than 1.5" to make my holes. These little net cups are a perfect fit.

you will be able to reuse these cups numerous times.
