Hi...Thanks for your reply No the other plants are not shading them ....The sun does not get blocked by the house till well through the season,and even then the sun still has access to 1/3rd of the northern side...This is only my second season growing tomatoes and I enlerged my greenhouse towards the house ?? between seasons?? and there is a change since the previous season with the Tomatoes along the house side not doing well even although they are not entirely out of the sun range ..I presume its being blocked for light by the house shadow ..in fact I am sure that is the problem...

The side opposite of the sun doesn't need anything clear.
************************************************
Thats what I thought ...The wind is a terrible problem particularly on the northern side when we get nor-westers and it lifts the plastic film..It seemed to me that I would not loose anything or perhaps even gain a lot by solving two problems at once by replacing the plastic with a solid reflective surface or as you recommend a bright white surface....Hence my post...

I will immediately start searching for something although I purchased some Alloy plastic Composite ( either side of a plastic core is a small layer of alloy...total thickness aprox 6mm ) some time ago from a scrap dealer....This stuff is really expensive and I got it for a song...It would be ideal....( this material has a story ...it was wrongly identified as completely alloy ..it was weighed and paid out as alloy??? So when it was properly identified as mainly worthless plastic there were some upset people..)

It will have to be repainted but its light,strong and easy to work with....

The Roof which at the moment is reinforced greenhouse film on a steel frame is being redesigned to give me more height inside (for my anticipated larger plants???? ) and I will be using corogated Nova Lite which should also give me a lot better light....and there is also my HPS lights...my CFL's ...My LED's Tubes or if i ever get it figured out my car headlights???? Why all of these ?? well I got them at a really cheap price as my friends were closing down the scrap business and they would have been crushed and worth very little....I really have now got some great lights if I want to use them....I am afraid my life has been hijacked by tomatoes??
Thanks Ron
