Niceguystarted grow question 5y ago
I use 600w led double swicth (veg/bloom) light.. At lamp's box show that at 30cm it can supply 33k lux. But when i checked with my phone using android app it show just about 4k+- lux at 30cm. So based on you guys experience how much height i have to place my lamp for now?

Does it show 33k when you move the phone real close? 25000 to 50000 lux is what's needed for plants to grow well. I dont trust the free apps. I would place it where you can put your hand under it for a minute without feeling any discomfort. Cheers friend

How to keep room dark during flower?How important is it to keep the plants in COMPLETE darkness during lights off during flowering? Thinking of running some ducting with cut-to-size furnace filter out the vent hole on the side of the tent which supplies air right now. Will that be enough?Week 1

Hi guys,
My LED light from my tent just stopped working, it might have been the humidity or straight water in there. The new lights might arrive 4/5 days to arrive. Do you think my plants are going to die? you can check my diaries if you need. Thanks for your help.Setup. Lighting

Does my LED need more red spectrum for flowerin?I have an HLG 100v2 LED grow light at 4000K. They say 3000K is better for flowering. Does it make any sense for me to add some cheap red LED strips to add red spectrum? I’d rather not buy another more expensive light if I can just supplement this one. See picture.
