  • Also, regarding not getting a straight answer out of anywhere...Honestly, if you got 4 builders to make plans, you wouldn't get a consensus.
    Unless you go down the path of putting down extension grade foundations (taking into account nearby trees, slope, clay type), filling a nice wide trench with MOT and concrete is going to be fine for a greenhouse.

    What are the greenhouse plans, out of curiosity? I've always fancied building a wooden one.


  • Imo, it's always worth making the right mix for the job.
    Am I correct in assuming that you want to do foundations around the outside, then have the middle be bare soil to plant into?
    Rather than having a slab, and raised beds on top?

    Around the outside, maybe dig 400mm down, put in 200mm of compacted MOT, and 200mm of C10 concrete mix.
    And put some rebar in if you're feeling extra (it's not that expensive). Just remember that if you put rebar in, it is an absolute arseache to rip the concrete up afterwards.
    Though tbh, unless you're really keen for the plants to root into the ground, I'd do a slab!









  • The answer is, you have to buy a Proper ™️ one.

    With active cooling, a power supply, and proper Lightning etc. support.

    I buy Dell WD19TB units second hand from CeX for about £60. New, they cost several hundred.
    Even then, they have issues (fans staying on, and a STUPID bug where turning off the machine causes power-off packets to spam the network).
    But for general work, they're very reliable.
