Grodan Gro-Smart Tray Insert 78 Cells (EA)

You half to use upside down for cubes 1inch and above Rockwool other wise good for macro and starter plugs grodan! I like using for cloning in a 10x20 tray! With a humidity dome and T5 light above it and work with that’s et up on table .. pull out mom clip clones put in plugs/ cubes and water from sides/ down to bottom .. don’t directly water them .. make them search for the Food.. kinda the whole point of this being elevated that and to prevent mold .. it allowed me to do what I wanted to do... for that I am thankful 100%+ increase in seeds and cuts vs paper towel method and a baggie with a propagation tray of course and my little secret .. (Hint:Air) LOL enjoy !

The major complaint with it is that I use anything but a 1.5 Inch seed started (commercial) for the seeds I wanted to use the small pebbles to drop the seeds onto but the holes in the bottom are too large and the pebbles fall through unless they are large. If using rock wool cubes the roots should come out easily. So I give it between 3 and 4 stars overall.

Works great. If growing hydroponically. But have found the same product at a store an is only $15 for the exact same product.

Lived up to the sales pitch. Keeps the bottom of the cubes out of the water and keeps them in a nice stable position.

After buying traysthat don't stand up it was nice to find these. They are very versatile and plan to use both sides.

Used with the Early Grow 93807 Domed Propagator, 2 Height Extenders, Green. Couldn't be happier.

fits the 1.5 inch rockwool slab perfectly, was great for starting my plants

Great product, however twice as much as any hydroponic store...

Solid! Now I just wish it came with a sturdy container as well!

Simple, and works as advertized! Great addititon.
