what are the effects of the light cycle being longer then 24 hours?

[Flail 222]

since we've traditionally used a 24 hours cycle for our plants.

18/6 12/12 and 10/14....

has anyone tried a rolling light cycle? say 18/10? or something similar?

this one wonders the pros and cons.

i think its the 12hrs of dark that triggers flower not the amount of light. so u can add hours to the light cycle while keeping the 12hrs dark. so u could use a cycle of 14/12, 16/12 or maybe more. i changed my cycle from 12am-12pm to 12pm -12am by adding 2 hours to my day cycle for 6 days. with no adverse effects.

i've heard about it, but never saw it applied, would be nice to find a report i'll look a little on the net ^^

Would be even cooler if someone on sh had tried it ^^

I'll be following that

i just did a few calculations and u can do a 16/12 with a standerd digi timer.

set timer as fallows

monday at noon on

tues at 4 am off

tues at 4 pm on

wen at 8 am off

wen at 8 pm on

thur at noon off

thur at midnight on

fri at 4 pm off

sat at 4 pm on

sat at 8 pm off

sun at 8 am on

sun at midnight off

then the cycle starts all over again

[bozoph 696]

the diffrence is in hours of sun per week

a standerd 12/12 cycle get u

84/168 hpw

a 16/12 cycle gets u

96/168 hpw

that is like a whole extra day of sun every week. over the couse of an 8 week stain, u gain more then a weeks growth

[Guest Ghost_doG]

Is it theory, sounds bad ass!

Peace!

I like that info , will it work ? got a grow coming up soon and i want to try that , should work and dont think it will stress the girls at all.

[Dust 6,284]

Well i hope for you it will

And if not, it will be good to know for the following grower that will want to make it. But i think i already seen something of this kind online, probably on icmag or mrnice don't know.. ^^

Keeping a close eye on it

[Flail 222]

I like that info , will it work ?

it works in theory on limited practice expressed by bozo, those willing and able to push the envelope should do so

for the bold willing..there might be risks involved to the plants there might not.

[bozoph 696]

i would fully implament this cycle. but my lights r on at night(9:30pm-930am) for heat reasons. maybe next winter i will try it when heat is less of an issue.

[Guest Ghost_doG]

It's not that i aint bold but don't ask me to be Abraham

Peace!

[mopman 985]

mmm Currently running this light cycle at night aswell because of heat problems , only starting to drop temps slightly here. But hell a winter day here is like 16-20 degrees Celsius lol.

[bozoph 696]

this needs more looking in to. so as soon as this next batch of clones comes out, ill try this with 1 in the mini grow cooler

[autooprime 136]

24 hours of light is not recommended, darkness is necessary for certain plant processes, 20/4 max.

[bozoph 696]

u missed the concept autoprime

[Sizla 151]

i would love to see this in action !!!
