shade the top of my green house

[daveinbham]

Tay, May I know how to support the roots ( orkid,flowers etc.) May I know also the appropriate
light as Malaysia is hot the whole year . My plants become yellow when the temperature reaching 37.3
degrees C. Shall I put some shade to the top of my green house ? Thanks

Yes Here in Florida I have to use 70% grade shade cloth because of the hot sun. The experts say
you have to grow some plants like vegetables in full sunlight but I have been growing with
hydroponics under shade cloth for years.
