Advice needed, glasshouse or polytunnel
Hi everyone,
I'm new to gardenbanter. I have started a new step in gardening, I grew seeds for the first time this summer. I have been trying to educate myself on glasshouses and polytunnels but I'm still not sure, at the moment I can't afford a glasshouse. A lot of the seed packets say ' protect from frost ' would a polytunnel protect my seeds during winter or is it used for spring growing. Advice very much appreciated. I live in Ireland. kerrygirl. |

Provided it was kept frost free then either would do, just watch the cold condensation off the glass/plastic doesn't drip on the plants. -- Regards Bob Hobden just W. of London |

A lot of the seed packets say ' protect from frost ' would a polytunnel protect my seeds during winter or is it used for spring growing. Advice very much appreciated. I live in Ireland. kerrygirl. The problem with polythene is that it's transparent to long wave(LW) IR radiation so you don't get the "glasshouse effect" which entraps the LWIRR within the glasshouse. AFAIAA (old age& poor memory :-( ) when polythene was first applied to horticulture in the early 50s a simple experiment at the NIAE which was to set up 3 cold frames one with glass, one with polythene and one without any cover, I think the crop was lettuce.They found that on some clear nights when the air temperature above the crop was warmer than the ground temperature there was frost observed on the polythene covered lettuce but none on the glass covered, and none on the uncovered, the last observation was due to the relativly warm air flowing into the cold frame. So in certain circumstances it can be colder under polythene than outside. However it may be that modern polytunnels are covered by polythene which has been treated in some way to reduce the LWIR back radiation, I don't know the answer, perhaps some one more knowlegable than myself can answer that one. Polytunnels are very good at stopping cold drying winds from damaging a crop as are glasshouses of course. Hope that helps Regards Don -- Bold is Brown with the People's Purse. |
