|
|
Was thinking of building a green house .2.4m square .using ply for floor and .75mm upstand all round perimiter ,and fill floor with pea shingle. Have 2no windows for south wall and can aquire enough perspex for rest of walls and roof, so really all materials are free except the frame which i might make out of wood.
MY question is
1 -is size good enough 2.4m sq and 1.5m walls 30 deg roof pitch
2- pea shingle laid .75mm thick on floor ,acts as heat source at night iam told
3-perspex is old gone sort of yellow , will it be all right to use
dont want to spend much money on greenhouse just yet . really only want it for raising seedlings ,and maybe more in winter months if possible/
Take a look at pict ,know its big but cant see detail if smaller
thank you

Well the smaller glasshouse available to buy are 2 metres by 2 metres so you are going bigger. Maybe if some one had one of these small ones they could tell you how they got on. If you put a 3ft wide path down the centre that leaves 2 to 2.5 ft either side for benches or beds.

Seen a few people do that, sounds good. They are supposed to act like mini radiators.

Just means less light in winter but you may not need shading in the summer as some glasshouse owners have to install.
I think it is noble what you are trying to do reusing the perspex and all that. Where are you building it, near the house, down the garden, or on an alotment. |

Have a look at this thread http://www.gardenplansireland.com/forum/viewtopic.php?t=1260
Member AJ on it has a 6ft x 6ft glasshose he uses pictured. I suggest you make a new post on that thread linking to this topic and you may get a few replies as well. |

| Make the base concrete if you can. Avoid wood in contact with soil. Lay blocks or else frame and pour a base. |
