WOW awesome roots on the sesquipedale...Joann is right; it needs bright light even direct sun if you can gradually wean it in(11am to 3pm can burn leaves)...it feeds and drinks a lot...remember it originally came from Madagascar;where the monsoon rains can cause flooding in the area...but dont flood this plants they are Texans now.
thanks you.
I will adjust the light accordingly as I do read give them as much light as you can without burn. I really hate to keep anything in the morning sun after about 11 am..its brutal already. They burn fast. I can watch the leaves closely and harden them up some.. soft greenhouse grown plants.
As a rule you should give any orchid as much light as it can take without rebelling or burning. Paphs and masdys included. The lower light requirements means they will grow in less light not that they cant take the lighting. Keep these plants on the cool side and they can take more light. Thats the tough part right now is giving them the light and keeping them cool at the same time..Lots of fans from Walmart!!
mid July to mid August gives your area scorching heat but your atmosphere is very humid as I have experienced in one of my layovers in the airport and asked to stay overnight because of the NYC area massive brownout...
it would be nice to give them AC indoors for a month at least
the humidity is always there indeed, but you really need the cooling effect of that and a temp drop during the evenings. I can remember nights last year where the temp never got below 80 at night with well over 100+ during the day. the plants were dry as a bone at nights too,not a drop of dew. not to mention air so stale and still you could actually see heat waves at night move across the street in the light. you got the 20 degree drop but the plants didn't get any relief. they need to shut down and take a break just like we do. I used to think that hot and muggy nights were great. Only great if you live in the jungle and are a monkey swinging in a tree.
Im thinking thay are going to do okey weee see after a few months in texas heat how it liked it in december when it might be needing to bloom some for me
Nice looking seedlings, and these two species will do well with your warm and muggy nights. In my experience, sesquipedale's the much more adaptable of the two as far as temperatures are concerned, and it will also appreciate higher light levels than the eburneum. Good luck with your new acquisitions.
