[Fluff]

First day of real sunshine and some of my seedlings have been scorched.

Noticed a lot of  greenhouses are whitewashed inside.

I was assuming its watered down emulsion.

Can anyone advise what they use to whitewash the glass.

I can't think of the trade name offhand, but you can get something from the local garden centre that is mixed with water and painted on. It's inert and won't harm the soil as it's washed off.
Emulsion can be a right Beggar to get off....

If its what i think you mean they sell it in wilkos . you put it on the glass to stop the sun rays so much , i did read packet but mmmmmm  forgot what its called . i knw i said to get it off come winter to let more light in for the plants ..

i too spotted this in wilkos yesterday.  was near the fruit netting and things like thermometers etc.  am thinking of getting some especially as my thermometer was reading 38.9 degrees C in the sun the other day!! :blink:

A lot of people just drape debris netting over their greenhouse on our site. There was a lot of scaffolding round our site last summer, so everyone has loads of it.

[poultrygeist]

Coolglass or something similar. We bought a job lot a couple of years back when wilko were selling off their summer stock.

I would look but it's down the greenhouse and I'm enjoying a sit.

Wilkos is where mine was purchased. Not sure about it though it was a pain to clean, well it had been left for about 8 or more years. If you don't have a Wilko I could send you a packet, reckon I won't use it but would like to keep one just in case (not sure how many packets are in the box). PM me if you would like me to find the box.

I have been told that if you water down some white water based emulsion and paint the outside of the greenhouse, that it will have worn off by the end of the summer. Not sure if this is correct but sounds like it might work.
Anyone tried this ?

[gaz.grace]

i think i might go with the netting as i have some ... probly easyer. 

[scot-canuck]

its called coolglass and its made by a company called bayer. washes off with soap and water, though do test spots if using it on polycarbonate as it can stain 
you can also get special netting for shading your greenhouse (thicker than normal netting and thus more expensive)

I hang my old net curtains up on cords and then i can then pull them back if it turns dull again (like it did last summer )

Looks a bit naff.........but werks fer me
