Light schedule for Auto's???

I don't disagree. THC will be lower when crossed with the Russian garbage for it's auto flowering traits. As for hating auto's, that's your call. I stopped growing them and switched to photos but will still be growing a few of them outdoors next year. It's beneficial here in Canada with short summers. That said there is no wild pot growing for them to contaminate anywhere near by. I do agree with keeping good genetics protected, I think most want that. I think the only real way to persevere genetics is for people to protect them. It's growers that will make the difference by protecting seeds, growing true strains and producing more seeds. Growing a few auto's should not change that but I do understand your concern. Protecting original strain genetics is important.
No shit. I don't want anything that's been crossed with Russian garbage. We agree, lol.

I grow autos as a filler between my photo grows. i think they have their own unique spot, its neat having a plant that will just bud as long as you give it some light. I keep mine on 18/6 because i veg photos in the same tent and they do really well. I've just always thought it was common sense that weed needed at least some kind of dark cycle.

Ruderalis has low thc levels. I don't see how that couldn't lower its potency.
I always cringe when I read something like this. Auto's, just like photo have varying THC levels. Most breeders test and tell you what % of thc is in any given strain. So Pick the THC% you want. You're making it sound like the ruderalis is depriving you of massive amounts of THC. If the auto strain being offered is 25% THC are you just going to dwell on the fact that it could have been 26% ? Just pick another auto strain than thats 26%.

Tell that to the top auto breeders from 15' to just this year before getting real competition(Mephisto) as they run 24/0.
As far as light schedule goes I don't think there is any one right answer. I know your big on how Mephisto does it but I don't believe it tells the whole story. You need to factor in DLI. So depending on your set up it it may or may not be better to push you plants 24/0 depending on multiple variables including your light intensity and how far you can back your lights off, temps, CO2 and humidity control. I would argue that if you are going over your max DLI you would be better off running 18/6 or what ever.


I could be wrong, but I suspect @Oldreefer is maybe running some old school 1000w hps and dumping a ton of light on his auto's running 12/12.

@Zogs is right... I dump a bunch of light in my 12/12 schedule but primarily think keeping all other parameters close to spec makes more difference. I did run around 1500w hps but now run around 650w of mostly white lights.
Of course breeders are gonna rate their gear by the best/most/largest numbers and that requires ideal conditions...lots more than just light....then there's those who believe more light makes up for less of other needs.
Oh I could easily run more light but when ya run a perpetual grow for 15 years and ya jars are always full, why spend more to have more that ya don't smoke or get rid of. I'm way past needing something to brag about.

How old are those autos and did you plant from seed straight into pot?
I plant my auto seeds straight into final pots right after they've sunken in a glass of warm water sprout in 2/3 days everytime. I know you didn't ask me haha but I thought I'd comment.

Ive also bought some fancy smart pots from special queen seeds
Any advice..never used before..done all the research though lol

I can't really comment on smart/fabric pots ive not done any grows using them. I never had any issues with the old type pot's so just stuck with those. However I recently purchased some smart pots and fabric pots and will be trying them out next time. even without using yet I know they will be better because they offer something the old plastic pots don't. I know people who use that haven't said a negative thing about them so there definitely the way to go these days.

It's not required so much as beneficial. There is no arguing some use a 24 hr light cycle with success. Give this a read. There are other articles but this blog is ok for a few points.

The article is basics of lights cycles. Can you explain to me what cannabis does during the dark period that is "not required so much as beneficial" during veg? You jumped down the other guys throat about running 24/0 cycle. What's wrong with it?

So what your saying is you dont want to know what plants do during dark cycle and just choose to ignore it. That's cool, your call. Feel free to not let your plants have their natural processes all you want. If you have plants you can do whatever makes you happy.
Mephisto offers a scientific basis when they say 24/0. You need to present (or cite) your scientific basis for saying that dark benefits auto flowers.

Yeah thks for your reply thats what i thought. Wondeting whether to pre soak the soilnin pots befote planting seefs and then putting in tent under a 600hps dual bulb..sorry for bad text on my phone and only use one finger omdays..

That's what I do for my coco. Otherwise watering a seed in dry medium can cause it to shift and sink lower than you want for germination.

I didn't jump down anybody's throat and if you read my response it said do whatever makes you happy. I also stated that many run a 24 hour light cycle successfully, I just prefer to allow the plants to go through their natural process. What do photosynthesizing plants do during the dark period?
"Dark reaction is also called carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from the carbon dioxide and water molecules.
The dark reaction occurs in the stroma of the chloroplast, where they utilize the products of the light reaction.
Plants capture the carbon dioxide from the atmosphere through stomata and proceed to the Calvin cycle.
In the Calvin cycle, the ATP and NADPH formed during light reaction drives the reaction and convert six molecules of carbon dioxide into one sugar molecule, i.e. glucose."

As I stated, do whatever makes you happy. Can you choose to deprive them of their dark cycle, sure you can. As the grower it is your choice.

Hey, if my answer offended you some how I apologize. Take a look at my response above for a scientific explanation of what plants do during the dark period. Be it an auto or a photo it is still a plant that photosynthesizes and respires. It has natural processes it carries out in periods of dark and light. Can you choose to not give it dark, sure you can. It's up to you. Yes plants can be grown quite successfully in a 24 hour light cycle. I find there is no real benefit to denying the plant the natural dark period and yield difference is negligible for the extra power used. That said it is up to you what you want to do and if you are happy running 24 hours of light then go for it. Happy growing.

Take a deep breath man. Funny how some of you auto lovers are so quick to get defensive, lol.

I wasn't offended. Just curious whether you were offering an opinion or scientific fact.

has anyone tested their auto flowers to double check the thc...they lie about thc content because well you wouldn't buy low thc right? can your brain differentiate from 25 and 15% , doubtful.

this is sounding similar to breeder times.

I need to get into marketing smh

Nd if you think your getting the same % from seed LMAO ur funny ...
