Watering the Phals
My suggestion:
Go by the color of the roots, Phals have big thick roots if the roots are grayish the velum is dry and the plant needs watering.soon as hydrated the velum absorbs like a blot ink paper and the roots turn green. As is known Phals have no pseudo bulbs to store energy & water which is done by the root coverings of the orchid. Other suggestion weight of the pot which will feel lighter after the medium dries up. Lastly of course appearance of the leaves important indicators
No harm in leaving the orchid unwatered for short spells as per the weather conditions
