Advice please: vanda & oncidium SEEDLINGS

[Lani]

I've scoped out COC and Orchids North already, what great places. Last time I went to gordonvale I left with this beautiful big V. pachara delight...

I've got to stay away from that tempting place- I just don't have the room!

I know I'm in for a bit of a wait (I'm thinking at least 5 yrs cause they are puny). I'm thinking of these little guys as an investment, hopefully by the time they flower I will have a house... And a green house

Philip: I'm glad they look fresh. I think I will use small bits of charcoal and a bit of fibrous coconut coir in baskets. My other 3 vandaceous orchids are in charcoal and it seems to agree with them in my climate. Do you have any do's or dont's when 'hardening off' seedlings?

Generally the key to hardening off seedlings are 3 things.

Slowly acclimate the seedlings from a high humidity environment to a lower humidity environment.

Slowly acclimate the seedlings from a low light environment to a higher light environment.

Protect from the harsh conditions of the outdoors.

Each seedling will behave differently, so you will have to be observant of them.

The acclimation process can take a few weeks to a few months depending on the seedlings.

Larger seedlings usually take a shorter amount of time to acclimate than smaller seedlings.

Treat any seedling under 2.54 cm (1 inch), with care, they are usually still delicate and do not acclimate quickly.
