Easy Ryder and I need help making seeds

Easy Ryder 30 days from seed in DWC. I'm planning on using Gibberelic acid to make some pollen and I could use some help figuring out when I should start spraying to create a male flower. Anybody used GA3 on an auto-flower before?

as far as i know if you want to self pollinate a plant you need to do it around preflower so the plant has enough time to finish
honestly now would be a good time just let it finish completely pop a seed out and check what it looks like before you go choppin on it

I started spraying a lower branch on 8/17 with GA3 200 ppm for 9 days before I took off for burning man. When I got back the plant had exploded and was hitting the top of the tent I was growing in. The branch I had sprayed is a tall as the top now, I think the leaves died on the upper half of the sprayed branch because they got to close to the light. I'm not sure how to interpret what is going on as far as whether it is developing pollen sacs or if I just created some sort of mutant. Flowers seem to be developing fine on the rest of the plant as well as her sister. I have also included a pic from the lower part of the sprayed branch. Can people help me interpret these pictures? Thanks

Same plant, different question. This plant germinated 7/12 which makes it about 58 days, Herbies said these harvest in 90. This is a picture of the top cola - how would you say it's doing?

Are you currently feeding them bloom nutes? Most advertised finish times are usually early depending on pheno. Most autos I've ran usually don't take that long to flower, so you might even cut it close to the 90 days finish time. I'd give it another month and see how it looks from there. I've found I can usually fix the finishing times by when I choose to switch to the bloom nutes, I used to switch when plant started throwing pistils, the yield would suffer greatly but I could usually finish alot earlier. I now wait until the plant finishes all vertical growth, to maximize yields, but it usually takes a few weeks longer.

200ppm is a high dose of
gibb
last one i did i miscalculated the amount of gibb and mule'd my plant out every calyx had stretch between it >.<
ga-3 will move through the plant at a rate of 1 inch a day
at a application of 9 days i think it would be safe to call that enough to make a mutant

it also stops lateral root growth at around that dosage


But and there is a but
i read a study that showed success with spraying buds 3 days before harvest with 10 ppm
to up thc and cbd levels/ trich production

you have to do alot of research to use gibb
CS method is alot simpler
it either works or doesn't

Yeah, I think I over did it... My research said 100 - 200 ppm for 10 days and in addition to being at the higher end of the range I think I over sprayed as well.

@tekdc911 where did you read about 10 ppm 3 days pre-harvest?

UMMM...... ill try and find it it was a study on cannabis and ga3 let my stoner ass think for a moment and ill try and reenact my search lol

it gave me a headache reading it
and had to use wiki to figure out half the shit they're talking about but
what i gathered from the way its used on other crops and from this study
its usually used 3 days before harvest
cucumbers, pumpkins and stuff like that
i think it was 10 ppm if i remember correctly
and this was a vegetative study specimens were sprayed
with different levels and tested
looking back on it 10 ppm was what i came up with
that i was going to try because 10 ppm is used on the stem of fruit bearing plants 3-5 days before harvest to almost double size
and i was figuring auto's take less nutes so i figured it would take less gibb to get the desired effects just a theory

Thanks for that, it is pretty heady stuff and I'm not sure I'll ever be educated enough to understand the difference between sesquiterpenes and tree sesquiterpenes :)

It talks a lot about the difference between 100 and 50 uM - which from what you've said is the difference between 10 ppm and 5 ppm. I have to say that that is a really small amount of the stuff.

Have you ever read anything that would point to any dangers of using GA3?

its commonly used a few days before harvest in commercial vegetables
from what ive read almost everyone consumes it
and the msds shows little danger unless you're going to eat a oz of gibb in one sitting it appears to be safe
its already found in plants and used alot more then you would think rice production ,fruit's,
its how they make seedless grapes

Interesting :idea: Actually after reading the study this not beyond experimenting by the average person. However truly understanding the study is reserved for those with higher education. I was confused by what I read.
The treatment took place
with three times spraying at 24 h intervals. The plants were
harvested 1 day after the treatment.
This was simple straight forward easy to understand. Or was it, simple and easy to understand? I quickly scanned the report for and answer but apparently missed it. The experiment in this study was clearly done at harvest. However the study was suppose to be, as its titled;
The response of terpenoids to exogenous gibberellic acid
in Cannabis sativa L. at vegetative stage
The paragraph preceeding the harvest time spraying clearly indicates they were being sprayed in veg.
GA3 treatment of plants Cannabis plants were treated when they had seven pairs of
leaves.
Am I just missing something here? These are back to back paragraphs on page 2. Did they harvest preflowering plants that were basically still in veg? If so, his or her findings are somewhat useless since nobody harvests cannabis at such an early stage unless all they want is leaves.

yes the plants were harvested in veg
but the effects are very similar on a late flower plant from what i played around with it
