Those snow whites look excellent,living up to their name and covered in snow lol.
PPP also looks very good.
I have read through most of journal and looked at most of your pics and everything seems good.
One thing i did notice is that you have the hps 12" away from the tops i have found that you can get a 400watt hps 8" away if you place a fan to blow the heat away from the tops across the bulb and the tops even with a smallish cheap fan like i have,cost me 6.99.
Anyway lovely plants,great crystals on the snowhite and a great colour on the ppp,good job well done
