Can we grow weed from MARS? (28h light cycle)

[Jylhavuori]

Some years ago I grew DWC HPS Master Kush with a light cycle of 28hrs using a digital 12-stepped timer (week days in it). Infact the timer was really cheap and good. It carried up to 2x600W HPS ignition, was 16A. (I just checked and that type is still being produced.)

At the time I was kinda just growing without any environmental monitoring, always high EC and stressed plants. I didn't take much notes on the vegetative period (20-8.) but saw a great difference in flowering structure and time, using 16/12. She flowered for 89 days and I've never seen such difference at inflorescence size! I didn't weigh the yield but it was close to double the mass comparing to 12/12 Master Kush. It was a clone. But not too much can be extracted from that grow since the control was so poor.


I'm certainly going to do more testing on the 28 hour cycle in the future, when I have bigger appartment to put one more tent. Or if I'd build a loftbed I'd have the extra room for about 120cm tent. Lots of things to test.. for example:
different light spectrums, light cycle combinations, feeding, senescence. Then later maybe such as epigenetics and so on.

I'm really interested about this too now that I'm better at growing and understanding the physics. Plus that we have cool new lights to play with!

Any input is welcome!

I wonder has this reached anyone... I found one diary from 2022 in another forum, but it had no valuable information or research. Just a random test.

I really think this is worth a look on behalf of circadian rhythm and its possible evolution

So why haven't you tried it yet? Should take one tent and a digital timer!

I have no excuses.. or wait, I do! At that period in my life my mental stability was annually lost...therefore raids and loss of equipment too Also switched to led at that time.

Now I have 90cm+80cm perpetual system in a 34m² flat, gotta build some extension or pause the perpetual. Flowering tent is only 180cm tall and that's no good for this experiment, I suspect.

On the other hand, a perpetual 28 hour system is not excluded. Just gotta have some results first.

I dont know where to start looking atm, but there are old forum threads from the 2000's that do talk about this. ICMag, i think. You can speed flower with reduced yield with an 18 hour timer (6/12), and you can gain more yield with prolonged flower with a 36 hour timer (24/12). I remember the 36 hour cycle took too long to be practical. However, I dont recall any picture proof within the conversation. Your use of 28 hours seems more practical. The 28 hour clone went 89 days, how long did the 24 hour clone flower for?

I gotta see those threads. Gonna search some. Thanks for the info.

Figures. Can get quite complex in many variables...

From that mom, only one clone was grown. It was 40cm taller and the budstacks were taller aswell, almost like she didn't want to stop building new sites. Even with the blue led there. The seeds, which I grew plenty in the days, were quite stabile around 54-60 days.

I'm really curious of how the plants with different genome would act. For example 14 hours of dark or even 16, when trained early on for high PPFD. Then, spectrum dialing could be worth too considering the effort - simple blue-red ratios to control biomass and height, which might form an issue some cases.

It seems there's not much to compile from.

Just gotta start it myself then - to see where it starts going with cloning 28h plants. I have no possibilities to make seeds. So a diary is coming soon.
