All my Phals are on heating mats! But it is also true that this particular one is probably 6 inches tall and the deli cup it’s potted in is 5.5 inches tall, so add that up, top of canopy to heat mat is 12 inches. I think these roots are healthy and maybe the overnight change of color is a normal thing. I’m just not sure what the color changes can be attributed to. My only understanding is that purple is either low Magnesium or cold. I keep the house between 68 and 72 year round for personal comfort (might change if bills keep going up), so my only guess is that it could’ve gotten a chill breeze in the upper 40s or mid 50s at night that maybe triggered that reaction. For the time being I’ve moved them back from the windows a little bit. Luckily my plant shelf is arriving this week so my Phals will be in a different spot under artificial light only.
