This phalaenopsis has the thickest spike i've ever seen on one of my plants and it is growing straight up.
Another of the four or so catt's in bud right now...
And this is blurry, but my Zygo has two spikes with lots of pretty buds. Again, this plant usually only gives me one spike.
I'd say from my results...I need to order two more of these and my other two racks will start blooming too. lol I don't know about anyone else, to me the proof isn't just the blooms, buds and spikes. It's the size, number and yield. I'm convinced these lights work 100%!
