hi - have new inside plants on open weave shelves with grow light and small fan for circulation - have read about temperature issues and am not sure what to do - I keep AC @ 78 (cost control - and I am comfortable) - but @ night temp seems to go up (everything I read says orchids like it to go down @ nite) because AC does not necessarily come on when sun goes down (nice humidity tho) - it never gets in the 60s here in house except in the winter when I turn heat on @ 68. My gut feeling is wait and let my two (OK lol) plants tell me if what I have arranged is OK for them - OR do I need to consider proactive temp adjustment of some sort? Oh - I can set up little space heater near shelves to boost winter temp for them.
I think I am probably just being 'nervous nellie' newbie who would rather not kill plants (but I know that's inevitable!) P.S. how much fan is too much? ie. is gently waving odonto plant leaves too much? I read they like cooler and breezy so fan is more focused its shelf - yes, my two plants each have a shelf to themselves. (right now)
What type of plants do you have?
hi thank you - I have one phal. Connie Moody - top shelf where the temp stays about 78-80 day and nite and one odonto. Pacific Sun Spots on the bottom shelf where the temp stays at 74-76 during the day but creeps up to 78-80 at night(even after lights out). I have been aiming the fan at the wall behind the bottom shelf so the breeze deflecting off the walls help keep that area a little cooler.(fan on 24/7) And I have been misting only the bottom plant in AM - and it always dries out so I hope no fungus problem. ---the odonto. was a 'rescue' from the half price table and already looks better(leaves standing up now and psuedobulb got unwrinkled after one watering)
Sounds like you are taking good care of them. Air movement is very important and you seem to have that down. In the winter, when temps drop, that will signal the Phal to begin a spike. I would not worry about the heat right now. I have several Phals outside in the shade and it is getting around 95 here with heat index up to 107. Actually, they are growing more since they left the AC at 73 degrees.
My Oncidiums are also outside with morning sun/afternoon shade and they are doing well. I believe your Odonto likes similar conditions, but someone else more experienced than I am will have to chime in.
thank you so much for the compliment...the phal came with a lovely spike with buds!-------'. This is as bad as raising chickens!! Lol from what I read the odonto. is very much like and oncidium - guess that's why they can 'cross them fairly readily - and sounds like it will like its fairly shady bottom shelf if yours are doing so well outdoors. Thnx again for the response. Lynn
My oncidiums get a bit more light than my Phals that are outside. But the temps are the same
Hi Turt., I live in Phoenix and the indoor temp is kept at a constant 78. The orchids I have are Phalaenopsis and they do well in that temp. There's a season that the temp. drop (nite/day) will spur the plant to grow, and with your winter temps. that should be ok too. Find a spot where the sunlight isn't direct and temp warmer, like near a window.
Air circulation is good if it doesn't dry your plants out. Heat in the winter might have the same affect. They like humidity so you have that going for them.
There's going to be a lot of advice for your question (coming soon) so be patient. You'd be surprised how resilient orchids can be. Killing them isn't inevitable, not buying more is! Welcome to RVO! T.
I was told recently that Phals like heat - I didn't know that. They need the winter cool to form spikes (about 10-15 degrees cooler than they are used to for several weeks, I think). I wouldn't worry about it being too warm. I've had really good luck keeping my Phals alive for years and years, as long as I make sure they have good air circulation at the roots. I forget to water them sometimes and they do fine. I am not likely to over water though. Mostly they are pretty tough as long as you don't rot their roots or tops. I bottom water - soak them in a tub for a while - every week or so, depending on if I remember or if they seem wet or dry (wet = don't water). I've lost one in recent years to a potting mix that had too many fines in it, it compacted around the roots and killed them.
I don't have the Onc/Odontoglossums down, though I'm encouraged that my Onc. Sharry Baby is sending up a huge fat spike on its new growth! I'm still experimenting to see what works for me there.
I live in a dry climate, hot in the summer, cold in the winter. My orchids are all inside though. Humidity is low, I kind of gave up trying to keep it high, they do seem to adjust. Keep in mind that what I do is in line with my climate and growing conditions. Good luck!
Thank you Terry and Carol!
I've been reading 4 articles that were written about studies that Texas A&M and M.S.U. conducted on growing Phalaenopsis. They're great articles about commercial growers and the processes they follow to mass produce Phal's. I plan on following the information and I'm convinced the techniques are the same whether you're growing one Phal or thousands.
They cover everything you need to know, and I do mean EVERYTHING!
If you're interested I'll send you the link. It was actually introduced to RVO by member Ron-NY years ago. I think it should be required reading for Phal growers!!! Let me know, T
