Example I have strain that I cultivate in same circumstances
Impregnated female flower so full of seed
Female flower not impregnated
Female polyploid not impregnated
So how do yields compare ?
Theory has always been that pregnancy
(Seeds) lower the yield by mass
Yet I can t find any research papers on the subject
Who s got some answers
Specifically seeded versus non seeded
Same strain same circumstances during grow is what interests me
Thx
I’ve always thought it was the weight of the seeds that throws off the comparison. They should be removed in order to compare. I would guess that yield does go down substantially, but potency would go up, because the plant’s cannabinoid production is not spread out over as much flower. The seeds dont contain cannabinoids, so they have to go somewhere else.
My guess is less cannabinoid potency on seeded crops, simply because the plant isnt spending time trying to grow new impregnating spots (calyx), instead its spending most of its energy on making sure the seeds are fully mature.
However looking at cannabinoid ratio to terp ratio, i would bet the pollinated crops make more terps, since its got something “nutritious” to defend. That guess is simply on the ratio, im not saying if u seed an acre youll get more terps out of it, im just saying that the ratio of terps to cannabinoids should be sligthly higher.
Another fun fact, if plants think they are going to be eaten, they will throw out more terps. Throw some insect frass into your foilars and the plants will think they are being eaten
I have always wondered what the results were from pollinating only a single branch on a plant. How does that affect the rest of the plants production?… I started paying more attention and this is what I found, From my experience even if I pollinate a branch or two the overall production of that plant is drastically decreased in both yield and terps…. I just think once pollinated to any level the plant has completely different priorities. This is just my experience and look forward to seeing what you find in your research @Roguelab
We have a plot of grain hemp planted nearby to a cbd plot. When we are taking samples of the cbd for r&d compliance testing we have to tell them on the intake forms if it’s been pollinated and to what extent.
We are studying what the effects the grain hemp pollen has on the cbd hemp production.
Different varieties (of female plants) are more or less likely to get pollinated by one variety of males.
If I’m trying to produce seeds without knowing which variety will impregnate which, open pollination of many varieties is more likely to produce seeds than controlled pollination.
I have also noticed a difference between if the pre-flower calyxes are pollinated or the main flower calyxes.
If the pre flower calyxes are pollinated there doesn’t seem to be much effect on the production. If the main flowers get pollinated in week 3-5 that’s where I have noticed the most negative effect on production.
Some products are even marketed to control the extent of pollination if sprayed within this window.
Here is an example of a variety from feminized seeds that was pollinated early on but isn’t full of seeds and is doing very well. The same plant is pictured two weeks apart.
think I’m gonna do a side by side this coming seed run…. Gonna do 5 or 6 strains all with same environmental conditions and feed. I intend on photo documenting the whole process and will be collecting all relevant data, weight, potency and terp profiles…. Also half of them will be Fem and half Reg seed producers, unfortunately I donor have a Polyploid to work into this unless someone want to send me one I would be happy to work it into the the experiment
