Greenhouse base

[noviceveggrower]

Hi,
Bit of a daft question but if I bought a greenhouse do I need a base?
Was just wondering if I bought a greenhouse without a base but fixed it down to slabs would that do?
Thanks

You don't need a base but it gives you extra height in the GH and, probably makes it easier to fix to the slabs. Don't quote me though, I'm just a looker-on with these things

I'm only just over 5ft so height isn't important as long as its not to high

When I got my first greenhouse I decided the cost of a base was too much so I just dug out a rectangular trench, filled it with runny concrete and laid a course of bricks on top. This worked fine. However, using a base does give extra height and unless you're a shortie you may find that useful.

My GH was given to me without a base so we laid concrete footings to bed breeze blocks then fixed tanalised laths on top after that the GH was screwing through both lathes and blocks.

That's exactly what I've done with No2 GH. I'm 5ft on a good day but I would prefer it a little taller...toms from tall

Mine is bolted directly to the patio.

I lowered the beds inside my greenhouse, after using it for a season, as I thought I was missing out on cropping height for Tomatoes etc.

But my greenhouse is a not-very-tall type to start with.

i have one 8 by 6 that i placed on old fence posts laid down with no floor but it is a sheltered garden wind is not a problem if it was i would have used concrete just around the edge of the base and bolted down i too have dug the floor down by 10" only problem with this is i fell in three times before my tiny brain got used to it

I don't have a gh now but it depends if you want to grow in the ground or not but a slab/concrete floor will absorb the heat from the sun and then give it back, something else to think about

I think putting it on slabs would be fine but you'd need to level the ground first to ensure its straight so no pressure is put on one side cracking the glass.

Of course if you fancy the effort making a concrete base this would offer more stability. In terms of quickness I just out down two large sleepers and put breeze blocks between the other two edges. This have given both sturdiness, low effort and height.

When I built my greenhouse a few months back, I built it on some slabs and then knocked some small posts into the ground. I then secured the greenhouse frame and posts together. It's rock solid and doesn't move about in the wind.

My father in law has made a concrete base. Dug out a trench then lined it with wooden shuttering. This was done last year. This bank holiday we are chipping original bricks off ready to put on top if the concrete base. Should be about two brick high.

I reused some bricks in a similar way and regretting it now as they are crumbling. Water runs down both inside and outside onto the brick course (there is an lip on the sill which I suppose should mean the water should drip clear of the brick base, but it doesn't!).

If I was doing it again I would use engineering bricks.
