To keep them from drying out, I am taking the lid off and wetting it instead of spraying (as I read it is better than directly spraying them). I tried reading every single scrap of information online and am using the methods other's had success with. They need a ton of humidity right now to get their root velamen going so I only crack the lid a little during the day time. Of course today is 95% humidity outside so it won't hurt. Once a week I plan on taking everything out and re-sterilizing the plastic container with bleach. I sit it in the full sun to dry since I am learning that the suns rays actually can sterilize pots and such. This is such an exciting endeavor...I hope I will someday get to share pictures of flowers from these tiny plants. A few of the points other's made when growing Ghost orchids:
Never put all your seedlings onto one medium. If infection sets in you won't lose every plant that way.
Wood mounts that are successful include; Pond Apple, Queen Palm, Cypress....basically a hard wood with a deeply creviced bark.
Other mounts include wire mesh, wine corks, clay pot shards
To attach them to the mount, superglue is mentioned as the best in many posts
The first month is critical; while the seedlings need high humidity they cannot be constantly wet wet.
Fertilizer sprays are not tolerated until the seedlings have the white markings on their roots. The markings are called "Pneumatodes". They act like pores allowing air exchange and photosynthesis. They cannot process fertilizers until these white tracks/spots appear.
One other very important thing, you must be careful when de-flasking since any damage to the tiny roots will mean a loss of that plant.
In the evenings, one snail can eat an entire container of ghost babies. It is recommended to keep a lid on the container at night until plants are larger and need more air movement.
Ghost orchids grow a foot to a few feet above stagnant water. While most orchids like air movement, these do not. If air movement is too much the roots will dry out. When kept in a collection it is recommended they hang over a stagnant bucket of water.
And lastly; everything must be sterile, including your hands when working with freshly unflasked ghost orchids. Bleach, microwaving, boiling...there are more than a few ways to get everything sterile...and everything that touches your ghost orchids must be sterile. I will be spraying the spanish moss with physan once a week when I clean out the container.
Oops, almost forgot. Once the plants are larger...in a few months...someone recommended using "rapeseed cake" as a fertilizer. They said to break off a piece and superglue it to the top of the mount so when it gets watered it gets this fertilizer. It is my understanding you get tons of blooms with this method. Rapeseed cakes are normally used with Bonsai and can be found for sale online.
I hope this helps. Anyone with questions about where I found the information I will be happy to private message where you can find the articles and posts.
