Light Filter for Purple Leaves

[Brooke]

How old are your seedlings? They don't appear to be very young in the pics but I know pics can be deceiving.

I've grown out several flasks of phals and find they will color up in sufficient light. After 7-10 days out of flask and planted into compots of sphag, the plants have adjusted to my humidity levels, I move the seedlings to full sun until about 1 p.m. and then they are shaded.

I agree the wrinkling of the leaves is a humidity issue and either the bark is not staying moist enough or you have lost the roots. If you have any feel for growing in sphag (some people hate it) young phals really do well in it. Phal seedlings actually like to be repotted every three months and always have a noticeable growth spurt after repotting. If you prefer bark, I would suggest a much smaller diameter to hold more moisture.

If you want to increase the humidity around your plants, sit the container in a plastic bag with the top open. Enclosing the entire container can quickly lead to fungal problems which can wipe out young seedlings within a day or two.

Your light set up cannot be too bright for the seedlings. For maximum growth, they should sit about 2" below the tubes.
