The only issue I can see is they might hold too much water around the stem and would need closely monitored at least to begin with. I use 3" cubes and still sometimes get stem rot especially around the time of first transfer.

Why not use Jiffy 7 or coir pellets instead?

It's a shame you can't get Cheshunt Compound any more. It was used to stop/prevent damping-off diseases.

A good tip for nft I use to do was either sit a clay ball on each corner of the cube to raise if of the mat a little or tile spacers works well
U may need to hand water the first couple days but once roots hit the mat the plant is away
