Hi again!
Its January and my phal has no sign of spikes. This is the time of year when temperatures in Manila are coolest at night. However, lately it has only gone as low as 26 deg C. So I was thinking of transferring the phal every night to our airconditioned bedroom where the temp reaches 21 deg. Becky mentioned this drop should go on for around 2-3 months, so would it be ok to keep moving the plant every night in and out? Anyhow is it worth a try?
