laying a concrete floor
Discussion
Got all the kit and have the shuttering up just the question is is it better to lean towards a wet or dry mix if i am wanting a decent finish on the floor
It is only for a greenhouse floor so strength doesn't need to be huge but it will only be about 2inches thick in some places so it can't be too weak.
I laid a bit of it last night and found if it was too dry it was a complete bugger to float so i am tempted to lean towards a wet mix but could this give me problems later on.

And no its not simple to dig it down further as i'm not hiring a JCB with a breaker to get through the rocks
What about hiring a piling machine? It is actually all the top soil removed and throughly pouned with a big vibrating roller and then sub base added which is then pounded again with a roller so it should be fine.
The ground is comedy hard with even a JCB struggling to dig more then a few feet down

The problem is at just 50mm it will crack. Your choice you can stop this from happening now or regret later.

The reason people reccomend minimum 4" is because with less than that, the expansion and contraction of the concrete you lay could be enough to crack it. It's nothing to do with the base underneath.
Mesh will help
The answer to your question is wet
My suggestion which you didn't ask for would be to use a waterproof self-levelling screed inside the greenhouse for the best finish.

How do you make a self levelling screed?Mesh will help

I have a large pile of gravel and a small pile of sand and a fiesta full of cement bags
(fiesta is currently being used as small mobile garden shed/greenhouse which is great as you can drive your garden shed around the garden to where you need it.)
As to expansion and contraction i am making the base out of small bays with wood strips between them as expansion joints as recommended by my father who has been a builder for years and has always done it that way but is in spain so i can't easily call him
