It uses 385nm and 365nm leds. May slightly increase flavours and smells but beyond that will produce absolutely no stress response.

Distance from bulb or from reflector?I found content about the distance from grow lights to the plants. I Know that using a 250w MH bulb the distance should be in a range from 20cm to 30cm. But i dont know If I should measure the distance from the glass of the reflector or from the bulb itself to the plants. Help!Week 3

Lightning questionHey, Growers! This week I had to open together the two boxes, so now all the plants have both kind of lights. Do you think, it can have a negative effect on them, or maybe it's good at least for the 140cm height White Widow,because the bottom parts get some more light from there?

Too little lightI have now tried removing the WPM by smiering 40/60 milk/water on the affected areas. Deep inside the canopy aswell since little to no airflow passes here due to the plant being so deep in the pot. And apart from that the plant recieves 8 hours of light and I cant install a LED.4 years ago

Distance from pot to light during germinationWorried about our light power and distance to the pots, should we be running it at full power with the light higher in the tent or vice versa? Also very unsure about watering amounts in these early stages and is it okay for water droplets to be sitting on the growth? TIA
