I have the kingbrite 240 watt quantum board and I have mine at 24 inches but I’m wondering how close I can push it when flowering but I’m the hunt for these answers as well. For the dimming part I just looked at the spider farmer website on their suggested dimming percentage for the sf2000 which is actually 40 watts less so I adjusted accordingly but I generally use their recommendation for dimming.I have ordered a Kingbrite KB-W55-L560-240W samsung lm301b/lm301h with epistar 660nm red led strip light for my second grow in a 2x2 tent. I'm looking for advice on how to determine the optimal wattage settings and height from canopy for both veg and flower. If anyone has already done the science and can lend a little help it would be great I have the Korona App to measure LUX but no access to better meters. My first grow and current veg light is a 100w no red UFO and im hoping i can increase my yield with better lighting set up properly during late veg and flower.
Ya I thought it would come with a chart but it didn’t so I followed close to what spider farmer suggests for the sf 2000the light will come with a suggested use chart with the stages and the settings. start in the middle range, watch the plants. if the leaves are pointing upwards, and no major tacoing, yellow tips or crispy leaves you are good. i lower or raise while watching the plants respond. but i have no life and watch my plants all day. lately ive been using the lux app and setting the lights that way. the accuracy is fine for setting the lights, especially if you watch the plants
Your korona app can do DLI as well. Be sure to use a diffuser with that app. A piece of white paper to cover your camera.what Lux ranges should i be looking for at the center and corners during veg and flower?
Does the manual for your light provide a PPFD map showing values at varying canopy distances and light spread from center. I would let that be my guide. I would start high.I have ordered a Kingbrite KB-W55-L560-240W samsung lm301b/lm301h with epistar 660nm red led strip light for my second grow in a 2x2 tent.
