i have a grow box in my house. i upgraded to some higher wattage CFL bulbs.
im using two 42-watt warm white CFL's. totaling 5400 lumens of light for the plants..
im currently growing lemon balm, a few different coleus plants, chocolate mint, spearmint.. an unknown wild flower i picked and cloned.. and some kind of rubbery plant a snagged a cutting of from lowes :P
my plants are stretching. growing funny & ugly. and the leaves on the lemon balm have dead brown edges.. i read that using only warm white light can cause this due to not getting enough of the blue spectrum.. i also read that "warm white" is better for more mature plants.. but i have mature plants, and they were fine until i got these warm white bulbs. now their doing the same thing...
should i replace them with "cool white" or "daylight" bulbs?
ive heard daylight is the best. but i think i might need more blue spectrum to help fix these plants.... these are pictures of the lights (not as yellow as the camera made them look), how it made my chocolate mint grow, and what its doing to my lemon balm leaves.. (i guess you have to click on the image to see the full view)... but suggestions?
