I am all for recycling. My new shed is being fitted out with cupboards and shelving and a work top from my old kitchen that is currently being replaced. In the shed previously I have had matching heavy duty black plastic shelving with poles supporting the solid shelves. They are the type you might use in a garage. I wonder if I can recycle and use these in the greenhouse. What do you all think? As they are solid shelves I am thinking of drilling drainage holes but my main concern is would they attract too much heat? My gut tells me it should be fine but I have a niggling doubt so turn to you guys for your thoughts  TY |

I think I know the sort of shelves you mean - we use them at work.
Weeell.... my first thought would be that - as solid shelves - would the higher shelves block out light to the lower shelves ? Mind you... I guess ALL shelves do that once you put the plantpots on them.
If black is a heat problem, you could always line them with heavy-duty "professional" grade silver baking foil. (You can get this from Morrisons). If you glue it down carefully, it should resist tearing ? Failing that... just paint them white with REALLY thick paint. (and it may take a few coats).

I would think they would be fine Cat you could always line the shelves with capillary matting or gravel trays to put pots on |

Those sound like what I use in the greenhouse Cat, kindly donated by my O.H. from the garage & I haven't found them to be a problem. I've got lots of plants in pots over-wintering on them, water just runs off the edges but I've put saucers under some of the pots anyway as I want to retain some water. |

I don`t see a problem Cat, go for it.  If OH wants them back then they must be worth a tenner.   |

Lol it's more if they are needed elsewhere in my shed, we are maximising the space. I have to be patient though OH works night shift on a rolling rota so we have to wait for his next early weekend off to do anything and only if dry and I am not a patient person, if I have an idea I wasn't it done! |

Never had a problem with TOO MUCH heat in g'house. Usually the opposite.

I was just thinking along lines of black attracts heat white reflects but I am going for it!!

If you can get some polystyrene sheets )available at places like Wickes) or from old packaging and place under your trays they will help as it is surprising how warm they become |

It would also reflect the light. |

Thanks daitheplant that's an idea too. I have 1-2 weeks before I need to sort so I can research what is cheapest/most readily available HAPPY DAYS |
