Hi All,

Am back keeping just a few phals these days and am growing on the out of flower phals in a 4 x 2 x 2 ft heated frame within the south facing greenhouse.

The key question is, do phals really benefit in having additional lighting in our uk winter months and if so, should it just follow the natural hours of the winter daylight or should it also extend the period, and if so, for how long , 12 hours ?

The other question, if extra lighting is worthwhile, what is the best source for my small area, without going overboard on price.
Appreciate a bank of leds might be ideal but they can be very expensive ; would a 4ft fluorescent tube do the job ?

thanks

Hi Ricky, the few phals I have do well on the window sills getting just the natural light available throughout the year. Your plants, in a greenhouse, will be getting more light than mine without the additional of any artificial light.
I think warmth will be more important for good growth in the situation you describe, particularly when winter really sets in.

Being as you're south facing I'd agree with Cricketerry that heating is more important. That said LEDs nowadays are pretty cheap and cheap to run.

Be wary of cheap LED bulbs; they probably won't do much good.

Above is right though, you probably won't need supplemental light for Phalaenopsis. It's more important to keep them warm.

Can't add much more to allay your concerns than what's been said already except that one phal I have is sitting in the corner of a north facing room with no supplementary lighting, it finished flowering about 6 months ago and has another spike with 3 branches already.
So not only should yours be okay without extra lighting, they may even spike ?
