I may regret the lower temperatures, but I don't want to heat my greenhouse above 60F at night. If I see problems developing I'll bring them indoors, but they will be a bit crowded if that becomes necessary for many. All but one or two of my phals are in flower or spike. One even has 5 spikes, but if it starts dropping buds that will be a sure sign that it needs to be warmer.

If it helps you can get these vegetable cold frames that are made out of doublewall polycarbonate sheets.
I know it might seem like a ridiculous idea but a bit of insulation on the bottom with a cold frame will add a few degrees. In summer it would not be needed of course but the cold frame would heat up additionally during the day and keep things a few degrees warmer at night. It really will make a small difference for very little cost.

I don't think this would work here in Mississippi where soil temperatures at night normally remain higher than the ambient air both in and outside an enclosure. As a result, the concrete floor and brick house walls of my (lean-to) greenhouse tend to provide warmth at night. The heat loss at night is primarily through the glass and air infiltration. At this point, the heat is off during the day because outside temperatures are high enough along with heat from the sun, but I'm sure this won't last. The coldest winter lows here are almost never below 15F.

When I took the plants back inside for winter time, nights were around 55F/13C with occasional dips around 10C.
I was a bit afraid at first but with decently warm days, they were happily growing and spiking.






My big gig took a rest after maturing its last leaf, but now it's cranking up a new one super fast.

The smaller took no rest whatsoever and keeps sending new leaves before the previous is even done.

At this point I don't know if a 'resting' phase is mandatory for adults, if it depends on genetics (gigantea have small regional variations, it may come from that? Or simply good/bad strains?), or if I don't provide what the big plant wants.
Alas, they are roots but I'm perfectly fine with that.

I did exactly the same at the same temperatures the three years prior to this year. Both spikes and flower count were very good, though my favorite phal (Cleopatra) that gave me three spikes last year has five now.


Edit: Bringing them in when it starts to get to 55C is a bit different than growing them at that temperature for 3 months or so. I guess I've find out.

I don't know what happened but I have a spike from one of the seedlings. I have them since Nov20, one year exactly. I may have mixed another one in the Gigantea box, but the sheets are the same.

These are Hybrid from Phal gigantea x phal Sogo White

Could this be possible?

dont look a gift horse in the mouth



and what gives, no pix??!

and seeing how we have the same seedlings but yours are a year ahead of us, based on what we got i think it is definitely possible for a spike this year. a couple that came out of our flask had over 4 leaves already so yeah, great job! i cant wait to see what it gives you!!
