Advice Needed: Last Week Flowering and Big Mistake ok, so my light is normally 15in. from top of plant canopy and i have great success...don't use expensive ventilation but there is plenty of air flow cuz i use a curtain and fans instead of complete enclosement...anyhow my Mandala's love the heat so i lowered the light another 3-4in. and all my plants have lost their stickiness...seems the light was too close for the Nirvana strains and the head colas are now very dry and the bottom colas are real sticky...plants were only under closer lights Rating: 5
