4 Inch Plastic Net Cups, Pots Plant Containers, for Hydroponics Aquaponics Orchids, 10 Pcs Black, with 20pcs Garden Tags.

Using for Kracky method hydroponic Set up. Size was right on for what i needed. Durable.

I put a coffee filter in these to help hold the soil and used them for starting vegetable seeds. The filter kept the soil in but allowed for air pruning of the roots. The filters were pretty much gone when it was time to transplant the plant into bigger pots and the roots looked really good.

I like that the slits on the sides start low so light can’t get through when using LECA however the lip around the top is too small, I’d like to return them but the plastic packaging tore taking them out.

I bought these net cups for a DIY hydroponic DWC. After cutting a hole in the lid of the bucket, the cup fit fine inside. The cup held my clay pebbles well while allowing the roots to find their way out to the nutrients below. They seem to work fine for me.

Small size and small slots, was what I was looking for, good value too

Now I can put my 1 gallon jars back in use. Previously they were fermenting jars. I bought them on Amazon and they served me well. 1 year later, different project. Different obsession. 1 quart mason jars don't allow for a lot of root growth. I'm experimenting with Early Girl tomato plant clones. I started them in a small hydroponic countertop unit. Once they all sprouted roots I knew it was time to move themm to a larger container. 1 is in a 5 gal. bucket with an airstone and water pump to spray the roots. The other 4 are in the jars with these net cups. There is no growing medium at all. I watched a video on aeroponics and modified with what I could afford. It's kind of a Frankinstein set up using hydroponics, aeroponics and Kratky.Life is just one big experiment.

All my orchids are dying that I put in these because there's too many slots the orchids dry out too quickly the bark medium cannot soak up water because there's too many slots these are not for orchids I didn't realize that since I'm new to orchids.Plus even though I have Amazon prime they want to charge me to return these. So I guess I'm just going to give them away. I'm rethinking Amazon prime.Revision: apparently I don't know what the heck I'm talking about LOL. These are fine for orchids you have to soak the bark before you replant. Three stars because the measurements aren't correct. These are too big for what I wanted but I'm keeping them.

Items arrived 1 day after the original expected date but no issues on arrival.

Good product. Exactly as described. Above average quality. I would happily purchase again and would recommend this product.
