Hi Mike,
I am a few hours east of you. I have had good luck with Phals in an east
window, set them back a bit from the window so that they do not get a chill
during the cool weather. Mike is in the "banana belt" of Canada, that's why
I said "cool weather" as it never gets cold (wish that was true). I also
have Phals in west windows but moved further back from the window. Our
house temperature drops back at night to about 16c (64f). automatically.
These plants have bloomed year after year. Our house Phals under these
conditions do as well as the ones that we keep in the greenhouse. My Phals
tend to sulk if they get to cool (heating problem in the greenhouse once).
I feed with a balanced fertilizer while the plant is in growth then switch
to one with a high second number (10-60-10 has worked for me in the past) as
the plant begins to spike and through out the blooming period. Once a month
I flush with clear water to remove any salts build up.
This method has worked well for me for years, hopefully some of this will
be of use for you.
All the best

I live in Southwestern Ontario near Detroit, MI. From what I can tell
(without a compass to be sure) my house gets East and West sunlight.
In the mornings one side of the house gets all the sun, and in the
afternoons the other side gets all the sun. The orchid is on the West
side (the afternoon sun side).
I've checked the day temps and they are around 22C to 26C (depending
on how much sunlight there is that day). In the evenings, I'm placing
the orchid next to an open window for a few hours to cool it down to
12C to 15C to hopefully make it spike. I don't know if the plants are
supposed to get the cold treatment all night or if a few hours is
enough.
Would direct sunlight still be dangerous to the orchid at this time of
the year? The sun is lower and lower in the sky as winter approaches.
So would the sunlight shining directly on the orchid still harm it at
this time, in the winter, and early spring?

Your best bet at
this time of year is probably to put the plant in front of a
south-facing window and supplement that light with a spot grow light.
Make sure that your plant is not too getting too warm during the day
when the sun shines through the glass (you don't want to cook the
leaves) nor too close to the window at night, when the leaves could get
too cold.
dd,
Is Mike (or are you?) in the Southern Hemisphere? If not, then putting a
Phalaenopsis in a Southern window will be too much (unless there is a
sheer
curtain there or the plant is far enough away from the window), and
adding a
spot grow light beyond that would be overkill. It's a Phal not a
cattleya,
and so if it's in a window it won't need artificial light unless it's a
Northern window ... unless of course you are in the Southern hemisphere,
and
your Southern window is like my Northern window, and in that case your
advice is exactly what I am doing in the other hemisphere. But before
Mike
invests in grow spotlights, I would like to make sure that he does not
have
an Eastern or a Western window, in which case sunlight should be enough
without grow lights ... until he has so many orchids that he can't crowd
them all in front of the windows.

I will try increasing the amount of light the plant is getting.
Can you explain what an MH light is? Can I just put the plant under a
room lamp and have the lamp's light shine down on it all day?
What watt bulb would I use? 40W, 60W? How long should I leave the
plant under this light every day? How far away should the lamp be
from
the plant? Or is using a room lamp a bad idea?

Mike,
I'm no expert at phals, but I have failed a lot--A LOT-- with
getting
them to live and to flower, so please learn from my mistakes. First,
your fertilizer is dead wrong. Ditch the 10-60-10. The "60" is a big
No
No. In nature, these guys only get a squirt of nutrients when a bird
flies overhead and has a bladder probem, or some rain forest stuff
is
mildly decomposing... Go for a more balanced fertilzer, and use it
at a
diluted strength--1/4 to 1/2 tsp per gallon.
Second, rapid root growth might be a "trying to survive" signal.
Mist
the aerial roots daily. Many of my phals that were growing aerial
roots
in response to semi-hydroponic media are now spiking--rampant root
growth and spikes. So, humor the aerial roots, mist them with mildly
fertilized water, and if you have sufficient light, spikes will not
be
far behind.
Your night temperatures are too cool. You are courting messophyl
cell
collapse, I'd guess. Boost your night temps to 60 degrees F, and
have
your day temps be at about 75-80 degrees F.
A wise old orchid dude once told me that if you can't get the sucker
to
flower, move it to a different location in your growing area. In
your
case, this might mean an area with more light or under light, such
as
MH lights.
Regarding bugs: Use the small cannons first: a weekly water spray
and
wipes with cotton balls drenched in rubbing alchohol can go a long
way.. If that doesn't work, blast them with chemicals, being careful
not to poison yourself, your family, or your beloved pets.
Good luck.

Orchid friends,
My Phalaenopsis is growing two new roots and no spike yet! The
plant
is extremely healthy and happy. It has 8 healthy leaves at the
moment.
I am fertilizing it with 10-60-10 (Schultz Bloom Plus) to push it
into
spike. I am even giving it the cold treatment at night for a few
hours. Day temps are about 22C/71F and night temps are about
8C/46F.
But there is no sign of a spike yet! I live in Southwestern
Ontario,
so the plant should be producing a spike right about this time.
The roots are pointy and about 0.5 cm in length. The tips are
reddish.
I'm assuming they are roots since they are growing down.
I also see tiny white and black bugs walking around. Which
insecticides are safe to use with an orchid?
What am I doing wrong?
Mike
