Lighting What's the best lighting cycle for autos - 24/0, 20/4 or 18/6

[Stinkycookies]

I vote non. I decided to split it 19/5 First plant i dd was 20/4. It gre so shurt and bushy maybe 2foot. With 19/9 during sleep they grow they strech in surch of the light at night. More dark more strech Means and gains in temps also can controll it but that total difrent topic
here in ont think where down to 13h light maybe 12 by now
i put a nl auto with preflowers out 1foot tall. and with in 4 days in green house it got to 4 feet so spindly and strech no lower node groth prety much halted and the toperaced for the sky had to put peice of dowlig to hold it up strait I kind of like the strech on 19/5

I go 18/6 I'm not saying it's the best but it works for me. Plus I save on electric and give the plant some sleep if it's anything like me it will appreciate it

I use 12/12 with the HID lamp at 400 watts then add a 25 Watt CF thats on for 24/0. No difference in yeild over 24 hour H I D.

I'd vote for 20/4 as that's my norm

I've started my White Widow autos at 24/0 three feet under a 315W LEC light. They are 5 days old. I'm thinking I'll go to 20/4 or 18/6 in a couple of days to save a bit on the energy bill.

You're better off turning your air conditioning when you're not home if you really want to save on light bills. LEDs are basically meaningless compared to most appliances in your home.

I plant 1 seed every week for the perpetual grow so I just do 24 all the time but I do notice a strain here and there stressed out by it. But it is usually one of those sub par free seeds they give you with your order.

I've been doing 24 hours light the first two weeks, then drop to 20/4 and some I've done 18/6, I seem to get better results with 20/4.
Here's my current mixed grow of autos and photo period, the photo periods will be placed outside to flower
