answered grow question 5y ago
18/6 or 20/4 there is no need to do 12/12 and will only hurt your yield. Hole this helps good luck

Bloom Light Supplement
I am a one plant windowsill grower, but having trouble getting enough light for bloom due to cloudy days. I have a three prong red/Blue LED light off Amazon, Wakyme, that is not cutting it. Would this lamp work? Two bulbs. I will have to suspend it from a clothes rack.

Yellowing leaves after first Mainline top. Light stress?

Light distance
So I just got the Mars hydro fc e6500 and put it in my 4x4. I’m about to enter flower next week and I’m not familiar with this light and I just want to know some tips on how many watts should I be using right now and light distance from canopy

Started the plants off with 60 watts. Increased to 100 watts today with a 20/5 schedule. Could I increase to the full 150 watts already or should I give them a few days with 100? Thanks in advance for any advice. It’s my first indoor grow with this setup and I’m still learning :)

Longer Light Cycle - Mid Bloom
Is changing the light cycle of an autoflower from 18/6 to 20/4 in mid flower too stressful? Doing so would bump my DLI enough to keep my existing light through harvest. She sleeps like clockwork but less so now in mid flower. Will she adjust in a couple days to a longer day?

Autoflower light cycles - adjusting mid grow
Autoflowers can grow in pretty much any light cycle. What are your experiences with changing light cycles mid grow? I am currently around Day 24, running 20/4 but the humidity in my grow cabinet at lights off is very high. How would adjusting to 24/0 affect my plants now? Thanks!

Too much lighting?
Too much/too many lights? Getting all popcorn buds/low yields. Getting a light meter this week. Going through by process of elimination on how I can get better grows. Read the manufactures instructions, but not good with technical electrical/lighting terms. Thank you.
