100PCS 2 Inch Garden Slotted Mesh Net Cups, Round Heavy Duty Net Cups Pots for, Hydroponics Slotted Mesh…

I have these in my DIY hydroponic system and they are working great.

I have a 29gal fish tank that I'm also using as a sort of riparium/hydroponics/aerogarden thing. Basically I am growing houseplants, herbs and, believe it or not, strawberries out the top of it.I got a large sheet of clear 1/8" polycarbonate, cut it the width of my tank's rim, and cut it the other direction a couple inches wider than these cups, and cut 3 holes in a row using a 2 inch hole saw. 2 inches is slightly wider of a hole than is ideal for these mesh cups, but it's still smaller than the diameter at their lip so they won't fall through. The bottom of these cups sits in the water about a quarter to half an inch when the tank is as full as I like it to be, so roots for plants can easily grow down into the water and there's a little wiggle room for changing water levels from evaporation/between top-offs.This setup allows me to have more plants on the tank than just planting stuff in those big ugly baskets that hang on the side, since the plants can grow in the middle of the tank. It's a lot more attractive than those big baskets, since it sits more flush with the water and doesn't have a hook hanging off the side. It also will reduce evaporation vs the tank being totally open to the air, although once the plants get growing, that difference will shrink. I'll reserve the big baskets for larger plants with bulkier root systems.Okay, so my review of these physical baskets is that they are nothing special, but a it's quite a good price for how many you get, and they got to me in a day as they are on prime. They are a good size, since a 2 inch hole saw works for making a frame for them. They are very light weight and fairly flexible, the slots are small enough to hold many types of substrate but big enough for roots to grow through. They are a good height for putting on top of a tank. Their rim/lip is flat, so they sit flush inside the holes on my frame and do not stick out at all really. I'd prefer they be clear or white, but black is fine.

This was a great product as described. Highly recommend.

Better quality than some of the other nets out there.

Use these for aquarium plants they work great

Works in my aquarium very good

These work great for propagation and hydroponics. Will definitely order again!

Perfect for planting seeds. Plastic seems thin but it works.

Less than 2" diameter. Falls into holes

Excelente

Not the standard size you'll find at your local supplier, these are smaller and will fall into your holes instead of sitting in them properly.Pictured: standard size on the left, vs this product on the right.

Its 1-1/5 and top edge is 1-15/16.Dosn't fit 2" system
