hi! i've tried 24/0,20/4,18/6, and 8/4/8/4. so far the 8/4/8/4 is growing plants that reach the size i want in a four week veg.

I would like to try out a 8/4/8/4, a 6/6/6/6, a 4/4/4/4/4/4, and a 12/5/2/5 photoperiod, is there a light timer you could suggest that could handle that objective something with multiple ons & offs in a 24-hour period?

Any digital timer with programmable memory can do that.

Cool...even 3 cycles in a 24-hour period like I want to do with the 4 on 4 off?

increasing veg light hours pays off... look at areas with high light level hours in summer and see... in my garden 20 hours is perfect and more a waste...after trying many light cycles ..switching lights and ballasts off/on many times a day is not for me or my equipment..yeehaw...there is no free ride,,plants need light to do their thing and longer light cycles are proven .. how much extra light is debateable...

Isn't there a trade-off there...by my understanding light energy is stored during the day and used during the night. I swear I've been told this by many a cannabotanist wiser than me that growth actually occurs more when the plant is resting.

Regardless I'm attempting to reduce energy consumption with not so obvious photoperiods on my meter and if I could reduce my veg photoperiod to something similar to my flower photoperiod without harming my plants it would add a further level of consistency to my energy useage.

On that note I started using 11 on 13 off for my flowers a while ago bases on the advice of DJ Short and noticed it really improve taste, smell and other phenotypic traits so I have taken that a step further now using a 10/14 photoperiod with no noticeable loss in yield and a quite noticeable improvement in quality...makes me think I'd like to run a 7/5/7/5 photoperiod in my veg room to sort of flip my flower schedule on it's head with 14 hours of light & 10 hours of dark in a day...if it soean't work right then oh well back to the drawing board, but if it does I will consider it a great boon.
