That would work great, but the price is a bit much for what youre getting in my opinion. You can piece it together yourself for considerably less.
You can get an 18" undercabinet t8 fixture w/ bulb for about $17 at your local builder supply store.
A timer isn't even needed unless you plan to go 18/6 for your cuts. (I leave mine on 24/7 so no timer needed).
You can get a vivosun heat mat for about $11 delivered on amazon. (I dont use one myself)
The trays and dome are about $12 and a bag of rooting plugs (50) are like $12.
So your looking at about $50 for everything including the plugs if you piece it all together yourself. Even less if you skip the heating mat.
