FINISHING THE CLOSET GARDEN: THE WONDERS OF WICKS

LOW YIELD

I had a 1 by 2 meter white flood tray with a .135 M3 reservoir, with 32 plants in it. It was a mix of sativas and indicas. We had a ventilation setup and CO2 hooked up with a timer. I used a 600 watt HPS lamp on a Light Rail.

UNINTENDED EARLY FLOWERING

I'm growing outdoors and some of the clones seem a bit retarded as the buds have formed on the stalk. I had heard you said to go ahead and remove them to hopefully re-grow til the end of the season.

I live in the mountains of Norway at 2450 meters. First frosts come early at this elevation, usually around the end of August. The spots I am considering have full sun and are covered with ponderosa and sagebrush rather than Aspen.

LIGHT HEIGHT

My garden is lit by a 600-watt lamp that is at its top height, 165 cm. Two of the three plants are 110 cm, so the plant tops are only 55 cm from the lamp. I am worried that the tops will burn if they get too close to the lamp.
