I'd love to see a picture. I ordered the PrimeAgra and some fertilizer I'll be using and am hoping to transfer it to s/h this weekend if it gets here in time.
I have my Phrag in lava rock in s/h and it loves it. I got it as a seedling, and have been waiting for years for it to bloom. It has been in the lava rock for more than a year now, and I have hopes that after waiting over 7 years it may finally bloom. I flush it well with clear water once a week, drain off the water and fertilize weakly.
This is the Phrag. Mem. Dick Clements in s/h. Not too shabby for less than five months of growth. Remember this had no spike and almost no roots when I got it.
My Phrag. Mem. Dick Clements in s/h has no bottom heat and is putting out a ton of new roots right now. I've got a 9" spike on it as well (this is new since I got the plant) and I obtained this plant bareroot (nearly no root!!) in September 2012. I can post a pic if you want.
