Rangaku
started grow question 4y ago
Has anyone ever moved a plant from HID lights to LED during flower ? Keen to hear from your experience as it’s looking likely that I’ll need to do exactly that in the near future .

Yes it can be done. A lot of times you may need to add a little more cal mag is about only issue. Plus Temps won't be as strong. Good luck. 🌱🌱🌱

Light Science
Has anyone watched some Youtube videos by Dr Bruce Bugbee from Apogee Instruments? I find his lectures on lighting to be the most straight forward explanations I have heard yet. I found his vid called "The New 400-750 nm ePAR Range Explained with Dr. Bruce Bugbee" to be eye opening on lighting colours. I have changed my LED's based on a few of his vids. He explains what plants really want and those Burple lights just don't cut it. For those that don't know he is a professor at the University of Utah that legally studies cannabis growth. He takes the science of weed grow to a whole new level.

Too little light
I 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.

Light burn or nutrient burn?
Hey guys. The tips of my leaves are starting to turn yellow and I’m wondering if this is a nutrient burn or light burn? I lowered my ppm feeding to about 250 a few days ago and am growing in ocean forest fox farm soil. And the light is an optic 2 running just the cobs at 24”.

Best LEDs or small HID to replace 1000W dimmable HID for small space
I'm using a 1000w HID setup I had from before, running at 50% in a cool tube. It's loud and not efficient. Maybe it's time I switch to LEDs or a 250 HID. I don't want to sacrifice bud quality but I'm low on funds. Any recommendations for a good light that will fill this space?

Learning more about LED lights, I'm kinda stuck . I can either buy two more of the current light I use (bloomspect SL1000) OR does anyone recommend another light in the same price range? Or info on what to look for .. not limited on space just funds. Unless I found a used one

LUX meter grow question
Can someone check out the LUX meter video and tell me how I should be positioning my lights? I think maybe I have too much light on them. My meter says 600 (x100) that puts me at like 60000 lumen. The converter I used put that to 1541.36 umol/s/m2 which is a lot of light already
