Hessian/burlap for sun-screening

[orchidsarefun]

I am using it as a sunscreen on SF windows. I have noticed though that the sun is brighter/hotter now we are coming into Spring, and it doesn't appear sufficient. I could double the layers, but I wondered if there was something better ?
In Spring/Summer I will move it to the West-facing window.

What makes you think it's insufficient? If it's temp (rather than light intensity), you might want to go with something lighter-colored.

I just have a sheer white curtain in a South window and I wonder if it blocks too much light. I need it for the seedlings though.

.....the leaves are warming up, they should always be cool to the touch...
I've gone from no protection, to hessian sheets, and now needs something with more protection - and that doesn't make my house look like a pot production facility !
Its just a problem for 3 months, when its warmer I am moving the whole lot outside.

They can burn easily at this time of year.

You could leave the curtain up to cover a shade cloth. A black shade cloth won't reflect like a auminum one and shouldn't be noticed.

well I got an aluminet shade cloth ( 50% ) after advice from an Orchid Society member and now have that up in the West-facing window. I have removed the covers from the South-facing windows.....its certainly a juggling act to get the amount of sunlight "right" over all seasons.
I really like the aluminet cloth, does a good job.

Cool, any pictures?

What makes you say that?

If you are referring to Andean species or standard cymbidiums, maybe, but a phal in the wild might be 100° or more with no issues.

That what makes this so fun. If it were so easy.....everyone would be doing it. Good job for figuring it out.
