Herms are either genetics or due to major issue due to stress.
The light scedule is less important for autos as the daily light interval (DLI), with strong lights one plant can get more in 6hr then another in 20 hours. Ensuring autos get at least a 4hr rest time is ideal.
Important things happen in a dark cycle, how important is it in autos vs photos is unknown. Until that time I would assume going from 18/6 to 12/12 while ensuring the correct DLI would be ideal but that takes alot of light power and is probably not doable in most cases.
Thatās why most auto growers run 20/4 due to not strong enough lights and others get away with 18/6.
However understanding DLI is more important than light scedule, although light scedule still plays a important role itās more so after the fact of understanding DLI.
Arenāt the ruderalis Geneās of an auto that make it an auto from Russia with a very short time with growable temperatures and the days are almost 24 hours light in the begining of the season itās only 3 hrs dark ā¦here ya go
Ruderalis comes from the Caucasus IIRC which is a long way from St. Petersburg.
It is russia tho ā¦right?
The russian ruderalis genetics were the first discovered and documented. However there have been some canadian ruderalis discovered and some from another place or two. Theres more but im not positive on itā¦ ive been researching ruderalis lately
Itās a āStan: Kazakstan, Uzbekistan etc which used to be part of the USSR. Not no moā thoā.
Had me second guessing I never heard or remembered the city area but i knew it was russia which is pretty far north i dont know Russia specifics I just was googling longest and shortest days in russia and knew it was from russia but was trying to get an extreme case of daylight hour swings to exemplify the shortness of some grow season 
Oh I had never heard of that @DefNSmokn thatās cool I love learning new stuff like that ā¦ I would definitely think there was a niched weed plant of Canada 
Yes but when you breed a regular photo with ruderalis how much of the ruderalis genetics is held onto? 10% roughly
That means you have a 90% photo plant.
You canāt treat an auto like a ruderalis and you canāt treat it like a photo.
This is what I have learned from my own experiences and research but I am all ears for a great auto decision!
It takes a while to breed stable ruderalis genetics into a photo strain. And then once you get the autoflower stable usually your potency is shot. So you got to breed more photo back into it. It looks like a ton of headache honestly
If you think about itā¦a photo say 20% thcā¦the rudi Geneās dont have 0 thc say 5to 8 % out of the 10% rudi Geneās its 0.5 to 0.8 % thc so 20% minus 10% would be 18% plus the 0.5 to 0.8 itās still 18.5 to 18.8% compared to the 20% of strait photo only 1.5 to 1.2 difference on a 20% photo not much of a difference I bet a solid 18.5 auto and 20% photo u couldnāt tell difference in the potency
Interesting perspective @fano_man
These new autos are doing great though, I should test some hut they are claiming 23-28%.
@DefNSmokn I agreeā¦
The only thing I would do would get an auto I liked then made duplicate seeds.
I donāt think ide ever breed autos to much work!
Oh I intend to take a crack at it. Just not soon. I still need to just practice growing for now. Lol probably play with photos first, make a strain I like, then try to make it an auto. Idk we will see i guess
Your idea sounds way smoother lol
Well Iāll be along for the show lol
Same here. Iām lucky to be getting 79 for my average yet. But itās cold here and Iām in an unfinished basement!
@Nicky and @Not2SureYet, are you both using the exhale CO2 bags? Iāve never used a co2bag so Iām curious what you both think of them.
Negative, I have one because I bought it in the fall when I was trying to finish a grow in a sealed shed.
Without a co2 reader I couldnāt tell you, it really depends on how your setup is. How many plants, how much does your exhaust fan run and where does it exhaust to.
Whatās the room like your tent plants are in etc.
It cost me 90$ and probably lasts 6 months.
I may buy another one.
My environmental conditions are pretty dialed in and my lighting is max, also running coco autopots is a mini hydro like system so co2 is really the only other boost Iāll get. Itās much cheaper then nutrients and at the time in a sealed environment I needed it.
They have bad reviews because most people donāt use them properly. It has to be used taking the variables into consideration.
These are not worth the money you paid for them and hereās why:
Fermentation will produce CO2 but not in high enough concentration to be worthwhile.
To utilize CO2 you have to have a sealed environment and run a high partial pressure: high enough you donāt want to be in the room.
To utilize CO2 you will need very high output lighting.
To utilize CO2 you will need to push high nutrient loadsā¦think hydro.
When CO2 is used, temperature and humidity go way up: this means complete climate control.
The bottom line is to properly benefit from the use of CO2 you need to run much higher partial-pressures than an exhale bag can provide and the facility needs to be set up in a highly technical manner.
Co2 is not for the beginner I try to tell first time thought about co2ā¦ the intricacy in your plan and how perfect everything needs to be and being ready deal with 100 to 200% growth ratesā¦ it seems like a job you can sleep atā¦ seems till you get 1500ppm grow in you have to stare at your plants and gauges till every thing is peerfctā¦ mishaps are not acceptable at this stage of growing small problems in normal co2 environments can be deal breaking in co2 grows
@Myfriendis410 your older and wiser than me but Iām still not going to agree until I can run a co2 sensor to test it haha.
I think I may still be getting a bit of benefits but without a co2 sensor Iām unable to prove what Iām doing is working. Although I do agree with most of what you said.
I still think they have their uses in certain environments, then again I could be completely wrongā¦ Itās happened once or twice before.
