Rivers.SND Posted October 10, 2012 Report Share Posted October 10, 2012 Hello, I plan building a new larger greenhouse and I need your advise, please. I can´t decide if I choose glass or polycarbonate for better colour of plants. I grow mainly VFTs and Sarracenias. I will cultivate plants in new GH from spring to end of autumn. Thank you for your advice! Happy growing to all ;-) Best regards Quote Link to comment Share on other sites More sharing options...
manders Posted October 11, 2012 Report Share Posted October 11, 2012 I think both block UV so not sure it would make much difference, glass will let slightly more light in overall. Quote Link to comment Share on other sites More sharing options...
Blocky71 Posted October 11, 2012 Report Share Posted October 11, 2012 (edited) As Manders said, also consider how hot your summers are, glass may need to "shaded" where as polycarb won't. I've used clear acrylic panels, they give appearance of glass but are very thin, light plastic panels.

will9 Posted October 11, 2012 Report Share Posted October 11, 2012 Glass must be shaded in summer and isolate in winter,polycarbonaat not ,if i must place a new greenhousse i go used for sure polycarbonaat ,clear ones in 3 layers from 16 mm thick at least.i grow plants in my veranda (port?)to ,this is whit polycarbonaat and the color of the plants is just the same like in the greenhousse under glass. Think glass is match cheaper but more expensif for isolate and shade,it s also match hotter in summer and colder in winter. But it s of course your choice,i think for the color it s te same, Cheers will Quote Link to comment Share on other sites More sharing options...

StuartF Posted October 22, 2012 Report Share Posted October 22, 2012 I've had both polycarbonate and glass greenhouses, and I'll never use polycarbonate again. I lived in a windy place and I got sick of chasing the panels down the street during a storm. Quote Link to comment Share on other sites More sharing options...

StuartF Posted October 30, 2012 Report Share Posted October 30, 2012 I had two greenhouses, one was polycarbonate, one glass. The glass one was unaffected, the polycarbonate got chased down the street. To the polycarbonate's credit, I suppose if a pane of glass had been blown onto the street then run over by a large truck, it wouldn't have been re-useable!

alexa Posted October 30, 2012 Report Share Posted October 30, 2012 I have always used glass and found that in good light, the plants colour up nicely. Alex. Quote Link to comment Share on other sites More sharing options...
casca Posted October 30, 2012 Report Share Posted October 30, 2012 If I buy a new greenhouse I will for sure go for polycarbonate, as Will said cheaper in winter no insulation and no shading needed in the summer. Although plates of 16mm thick is very expensive Quote Link to comment Share on other sites More sharing options...
