Plants staying at the same height

what do you mean by 6/2? I’m also trying to adjust my light schedule.

so a 6 hour on 2 hour off is equivalent to the 18/6 but the theory is sure the dark cycles allow the plants to use the light energy that's been stored and the recharge instead of overcharging and then using its stores at night

but honestly the answer any true questions to your comments I need to know some more generals are we talking high-value plants? I can work with that

But I dont know enough to try and guess at your problems ( btw only 1 year experience so I call my answers guesses)

thank you! I am growing a variety of flowers, and then herbs. I have a full spectrum light, and then a red/blue light. Would you recommend just using one over the other, or switch them on at different times?

so I believe your herbs can be considered more of your leafy greens which are fluorescent lights or the blue Spectrum and white spectrums which i believe Is just all colors (by the way I belive the more white a led looks when on pointing down the better it is these pink lights or BLURPLE arent the same, it's old tech) plus your own eyes and pictures will love you

But the reds are great for fall harvest plants or 90 dayers

That's my guesses and experience in my year of growing

so kinda a blurple vs white in looks (its the same plant I am making space and doing some new grows so moved it.... but it spent the first part of its life under the 1500w Equivalent led cob light

Have you grown a cucumber or zucchini before ? Think about how much space your used to seeing between each leaf stem ... and what not or *nodes* in some cultures ... usually 6 inches or more

So my 1500w equiv only uses like 250w btw did that to my zucchini

Hope it helps lol I know lots wonder about why light strength matters I suppose this is one thing to always consider
