New Grower life span of autos

[HomeGrownRx]

So I'm growing two strains right now, one of which is the afghan kush ryder. I've read 55 days seed to harvest and also 55 days of flowering while showing sex after 14 days.

So I'm on day 60 from seed and the trichromes are not even mildly amber, smoking it -d say its not yet ready. It showed sex at 21 days. Does this mean I should add the 55 days to the amount of days from seed to sex to get a good estimate of when it will be done?

That's what makes thge most sense to me. Another 2 weeks is what I guess my plant needs.

So the average autoflower seed to harvest say 55 days from when sex shows?

Thanks for clearing this up!

I've yet to have an auto finish in the 8 weeks that are advertised. Depending on the strain, 10 to 12 weeks from seed is usually how long they take. I don't pick mine till all the primary and secondary fan leaves are gone and the bud leaves are yellowing.

was wondering about this myself as I'm growing out my first round of autos right now (purple jems), and it seems like they're taking a bit longer than I had anticipated.... but then again, that's why I've never grown any until now... the whole "8weeks from seed to harvest" just always sounded like too much breeder marketing bs to me. I'm on almost day 40 from seed, and am just getting into the start of flowering really good, so I know there's still a good ways to go yet. Still cant say that I'm disappointed in them though

Breeder hype, that makes sense. I've also read that they only do so well in ideal conditions. So when do you know when to start flushing? I worry that the flushing may cause the plants leafs to start yellowing prematurely.

I've also read a thread about people not getting amber trichomes with autos, so I'm really confused as to when to start flushing and when to harvest. If flushing doesn't cause the yellowing, if its only based on age, knowing when to harvest should be no problem.

Thanks for the help everyone!

correct me if i'm wrong but ,in the plant world,isn't yellowing or color change a sign of decay? then it stands to reason that tricomes are starting to degrade when they start to turn amber, wouldn't you loose potency and flavor by letting the tricomes turn amber? or does the cbd ratio to thc increase the more the thc ripens? to produce the best medicinal quality,not smokability,i would think you would harvest at the peak of ripeness,instead of waiting for the plant to decline,thus loosing some of its strength.
this is probly not the place for this question ,on top of your question. mod please move this to the appropriate section. thanks. RSV1

no, the more information in the thread the better, no need for a new thread.

if i understand correctley, the yellowing is from an uptake of nutrients from the leafs in order to feed the buds to ensure reproduction. so yellowing leafs means the plant is at the ends of its life and realizes it, so its putting all its strength into producing seeds. i maybe wrong but thats how ive always seen it.

how the yellowing relates to content of thc vs cbd i have no idea. i guess i should go do some research, im sure there are quicker ways than tlc to detect realitive amounts of cbd to thc.

I understand it the same way you do Noobalicious, think of it as a tree... when fall (the end of the flowering session for a plant) rolls around, the leaves go from green to yellow as to put the force of it's nature cycle into it's death cycle. It's a cue as when to pull the plant from everything I've read. If it happens early in the flowering cycle or there's a lot of wilting associated with it then it's a feeding/nutrient problem.

If you want to understand the life cycle of a cannabis plant and what happens to the THC, CBD and CBN, you need to read Marijuana Botany by Robert C. Clark. It's pretty technical but the most comprehensive work I've yet to see. Well worth it.

right on muddy... seems theres a lot of misconceptions out there...

right on :thumbs:

typically ambering trichs means more cbds and better medicinal quality.. but it seems that that happens less often (strain dependet) with autos... however, they are testing out to have pretty high CBDs regardless. you should def read the marijuana botany book though.

Without a doubt. I still go back and read Marijuana Botany every 6 months or so. Learn more every time I read it.
