Hello, my friends

I've built a gh by wrapping kitchen plastic foil around one of those plastic shelves. I have a problem related with low humidity. In this time of the year until october it never goes higher than 25%. With temps never bellow 24ºC (75,2) my zigo and oncidium are, I believe, suffering because of that.
Hence the greehouse.

But I'm not sure about the conditions inside:

Day time max temp: 30ºC (86 F)
Day time lowest HR: 70%

Night time min temp: 24ºC (75,2 F)
Day time highest HR: 92%

I'm not sure if the max temp and max HR are ok for them.

Need your oppinion from more experienced gh growers

Thanks

I would certainly not like my Zygos to be in those conditions. Mine are grown rather cool along with my cymbidiums and temps as high as you are stating would be too high in my opinion. I think I would sacrifice lower humidity for lower temperatures. I'm not good with oncidiums but I would think they would be happier with lower temps too.

The coolest I can achieve inside is 24°C. Outside it gets up to upper 30's, even 40°C.
Better open the "oven".

Made some openings at the top sides to let warm air get out. Managed to get inside 27ºC (80,6 F) which is ok and HR=50% which is also ok.

Today was a relatively cool day with max temp 77 outside and not that much sun so I'm expecting those hot clear days to see the values I can get.

I think i would consider warm/hot growing varieties rather than zygos or oncidiums.

These were an offer... I couldn't say no to orchids. :D
I can grow and bloom a paph leannum which is a cool grower so oncidiums and zygos must be more sensitive.

Most paphs get warm/hot summers even when those that grow in areas with cooler winters. Oncidiums and zygos are much cooler growing year round, zygos in particular need cool nights.

My problem here is summer, too hot and dry.
Winter is the opposite, I can provide stable 10 to 12°C all day and night.

Dendrobiums should work well, or anything from northern indochina region, the cool winter conditions would encourage flowering and they will tolerate the hot summers if well watered.

I'm slowly buying (and receiving offers) a specimen from each of the most common genera. So far I have issues only with onc and zygos.
I have phals, dens, cymbs, paphs, catts, stan, xyl, Laelia, Miltassia, Bletilla... I think that's all... for now. :think:

I'd love to grow Masdies and Draculas (and the likes) but I know they simply won't survive my summers.

Something I could do is to move the plant outside at night. Our summer nights are usually around 19ºC (that's the norm).
By luch time I could move it inside, that's when temps really start to increase (it's a north balcony where I grow my cymbs).

I've always avoided to move plants in and out 'cause I don't want any pests inside but I can find a place to isolate the zygo from all the others. When autumn comes a good spray of imidacloprid would prevent a lot of the pests.
