No pollen yet - howcum?

We are not trying to produce oil though. James from loud seeds is pretty legit imo.

Effects of Nitrogen Level during Seed Production on Wheat Seed Vigor and Seedling Establishment at the Transcriptome Level

.

"In conclusion, nitrogen fertilizer affected not only grain yield but also seedling establishment and seed vigor in wheat. Pathways involved in nutrient mobilization and the antioxidant system played a pivotal role in seedling establishment and seed vigor in response to nitrogen level during seed production. "

I had a look at the paper, and suggest that it does not apply to the question about N. during flowering for cannabis. I say this because:

- The differences in seed viability were negligible between treatments. The only statistically valid result reported was the fact that initial green growth of plants in seeds from a normal N application was briefly higher than for seeds from plants grown with no N applied. To which I say, so?

Further, as far as I can tell, the fertilization regime used was simple single application of dry fertilizer, maybe assisted by a top dressing at one point, but I can't be sure. In any case, the analysis only looked at total N application for the entire grow, so there is no information that deals specifically with extra N during actual development of seeds.

I think that if a seed mom is kept healthy throughout the grow, the seeds will be as good as they can be as long as they are not collected too early, I doubt that more N later on will help, and if fiddling with it started lockout mischief, it could do more harm than good. Just my suspicion though, I have no interest in fiddling with dozens or hundreds of identical photoperiod clones to check the idea. Too little time, too many strains to play with.

Can't really compare wheat to cannabis.. Nitrogen is a vital part of all stages of wheat growth.. Not so with canna.. But there is credence to what your saying... The little quote under my name says "regenerative, organic grower".. The regenerative part has to do with the plants passing on certain information to their seeds.. For example.. A seedes mother plant grown totally organic.. Those seeds then get in the hands of someone who grows in hydro... Those seeds may need an adjustment period because the genetic info they may have received is based around organics. I think the health and grow style, environment, etc all have a huge effect on how well the seeds perform..

"the highest N application rate significantly increased the inflorescence number (118%), the seed number per inflorescence (65%), the 1000-seed weight (9%), and the fall tiller density (121%)."

"...the other plant characteristic, such as plant height, leaf area, seed setting rate, 1000-grain weight, and seeds yield, were significantly influenced by N addition in the both growing seasons. With increasing N addition, the reproductive seed setting rate, grains number and weight can improve the seed yield in growing season and heading year. "

True cannabis is not grass. I doubt anyone has done any studies on it for cannabis.

Im ok with being wrong, maybe I am. I just have not seen many people talk about the subject, so i have little to go off of. But it does feel like N is important for seed production.

We want to make big healthy seeds right? Not building oils like normally.

also. Wahooo!!!

N is important for seed production for sure - I do not doubt this for a nanosecond. Further the question that you raise is an interesting one and you are certainly not wrong to raise it for discussion. Whether research data bear on that question is a separate matter. The original paper you posted, I would say, does not bear well on the question of whether extra N during flowering would help cannabis. It is based on a different plant species, demonstrates near negligible statistically significant affects except when comparisons were between no fertilizer at all and standard rates, and in any case measured only total fertilizer application, not application specific to the seed development phase.

In order for someone to test your question's relevance to cannabis, at minimum the test would have to examine variation of N fertilization levels specifically during the seed development phase. Ideally this would be examined for a large number of clones of cannabis, but at minimum the species chosen should have some reason to expect results to be at least somewhat applicable to cannabis. I would love to see such a test, but am not in a position to do it myself.

Any way grobro, please don't take my posts as criticism of you, they are just intended to help interpret the available data.

It looks like high levels of N does increase seed yield by 30% in hemp.
The timing didn't matter though. AKA - adding more at the end didn't change the results.
Give it high N at the start - and taper down.

Sorry - not to beat a dead horse. Just autistic, and like talking about cannabis.
Hope people find it interesting. Not trying to prove anyone right or wrong. <3

Ok..it needs to be said..the title is no pollen yet..how come....
Cause they shy about being on camera, go watch some normal porn ya perv.




Joking.

Good point nonetheless. Should probably shut it down and move on. Turns out that there wasn't much pollen, but there was enough for a couple hundred seeds so far and still counting, so the original question is not much use any more.
