My equestris have dark green leaves and are in bloom , I grow the seedlings under 2 shop lights with full spectrum tubes , as the spikes enlongate the plant is lowered , hence darker green leaves .
I think the lack of heat has something to do with it as ones under a lot more light also are darker green then some I have seen . I just had a Phal. given to me it is a light green , but lacks the lush factor . The leaves are not plumpish/ juicy lol . Gin
