Need advice from humid-climate orchid growers

[Missi]

I am relatively new to growing orchids successfully.  I have a Grammatophyllum on the way and there's not a whole lot of cultural info on them.  What would be the best type of pot (or would a basket be preferred) and potting media to use for one that will be grown under roof in a lanai in South Florida? I read that this genus likes its roots dry very shortly after being watered, so I understand I must use coarse media...but which types are best?

While I'm at it, what do you all consider the very best orchid fertilizer?

Which Grammatophyllum are you getting?

Grammatophylum Broga Tiger

As far as keeping the roots dry after watering or rain, orchid pots would help since they have holes on the sides to dry them out faster. Grammatopylum is pretty big plants I think. Here is G. speciosum. Wouldn't mind having this one its big and pretty impressive.

I did a check to find out what Grammatophyllum Broga Tiger is-
Seed parent: G. measuresianum
Pollen parent: G. Tiger's Paw

And G. Tiger's Paw is-
Seed parent: G. elegans
Pollen parent: G. fenzlianum

Apparently G. fenzlianum is now G. rumphianum.

I don't know any of those, mine is G. speciosum. But the parents of yours are described as "large" or "giant" sized, hot growing epiphytes. So looks like you'll end up with a very big plant.

My G. speciosum was in the ground for a couple of years but didn't do well. So I moved it to the top of a 2 metre (dead) tree trunk where it's done a lot better. Gets a lot of sun which they like. G. speciosum are reputedly the largest orchid, with stems 1.5 to 3 metres tall. That's why I didn't want it hanging in a pot. You might want to check how large yours will actually become. Will give you a better idea of how and where you might want to grow it.

Thanks SO MUCH for all this info. I will look into all the species that went into making my hybrid! I hope I am able to get it to grow large/giant. That'd be excellent!

It's so awesome that you have G. speciosum! Such an amazing plant! I'd love to acquire one some day. We'll see how I do with this one first..

G. speciosum does fine (like most orchids) tied securely to trees in Puerto Rico. I have not tried any others of this genus yet.

I don't water or fertilize them, but it stays 66-89 here with lots of rain.

Big and dramatic-enjoy your Grammatophyllum!
