Can the Environment influence the Gender?

[bryleetch]

Very interesting thing you have going here. Definitely a start in the right direction to get some answers but I wish I saw this sooner so that I could've recommended something to better improve the experiment. A good idea would have been to put some female looking seeds in the pro-female conditions and the male looking seeds in the pro-female along with the vice versa like you currently have. This would give your results something to be compared to rather than just standing alone. Instead of "female seeds in male environment are X% male" you could also deduce "female seeds in male environment are X% but X% in a female environment". It just makes it easier to get a better conclusion of what's happening, especially on such a small scale it helps even more. Regardless, I still like what you have going here and interested to see what'll happen. A lot of people on her say they're going to experiment stuff but never follow through, glad to see someone is actually keeping their word. Good luck rest of the way!

If PCB's have the same effects on plants, would it mean a higher chance of herm or female ratio? Nothing against nobody but that's the end of the line when speaking about keeping your genes a float of the ocean.

I don't think(not 100% sure) they do have the same affect in plants due to plants not having an endocrine system with glands like mammals and other animals do. Some plants can actually absorb PCB's and render it, it's called bioremediation. Not sure if cannabis is capable of that but exposure to this would most likely just stress it to the point of going herm or die unless it is capable of bioremediation. In that case, we should propose growing cannabis to the EPA in order to absorb pollutants!

that's not a bad idea... maybe next time

there will be three possible outcomes to each room...3 males, or 3 females, or a 2/1 split.

IMO, the experiment will be completely inconclusive if I get a 2/1 split in either room.....so it has to be 3/0 to even be considered an indication or likelihood

Yea that's the downside of such a small sample but this is a good start to finding answers

it's all about my addiction to growing,,,, this experiment is just to fill in the void until Christmas.....I'll be leaving town, so I'll start my real grow when I return in 2015

This weekend I switched the lights to 11/13 (on/off), so should be seeing signs of gender in the next few days

The males in the female environment


The females in the male environment

 

[ISK]

It has been 6 days since I reduced the hours to 11/13 and still no signs of gender....hopefully in a few more days

9 days of 11/13 and still no signs of gender....last time I grew this strain it went 2 weeks without tripping, so I reduced to 11/13 and it tripped in 4 days.... this time I started with 11/13 but may still be a longer wait.

cooler nights now, as the both rooms can drop to 55-60 F at night

I revamped both rooms to give more space...also added jars to stabilize the Dixie cups as they were getting very unstable when dry/light

[ISK]

They are starting to show gender, still have 2 that I'm not a 100% sure yet, so I'll hold off on the results/pic's until such time

I am surprized that with 1500+ views that nobody has made a prediction....any takers?

 

[bryleetch]

My Prediction: 2:1 split in each environment, leaning towards 2 females in both environments and a male in each. Completely just guessing here lol

I hope I'm wrong though it would be way more interesting to see at least one of the environments have all fem or all male. Even if it doesn't turn out ideally, at least this gives a nice side by side comparison of how differently plants grow in these two environments.
Can't wait for the outcome!

I'm predicting 3 males in the female room and one male in the male room - based solely on height / bushiness!

I'll bet I have "skipped over" (not looked in) this thread a hundred times. Because, i guess, like some people, I feel I already know eveything (LOL). But, ISK, "You Da Man!"! I don't think I have ever seen an experiment run here at RIU with such downright enthusiasm and "follow through" - not to mention taking all the "suggestions" into consideration. The sample size might be small; but like you said, "There is always next time". THIS IS THE BEST EXPERIMENT I HAVE SEEN CONDUCTED HERE! Top marks for thoroughness and regular updates.

Anyway; back to the original idea behind the experiment. Let me make a brief statement about what my old freind / mentor once told me. Predetermined is such a "harsh" word, it's like "predestined", very matter of fact - "That is the way it will be". Seeds are more like "predisposed" - they are more likely to emerge either as a male or female plant - but that can be changed / affected by a number of factors. Predisposed is just a little more "iffy" than predetermined. That idea may not be very scientific but it is a hell of a lot easier to understand!

There was a study done. If you plant 100 of good seeds and all germinate. If you have over 60 females that's a female dominate strain and planting those seeds in soil that previously grew a male plant, makes around 90% females. In male dominate strains the results were about 50% increase in females with male soil.
They hypothesized that having the male hormons left in the soil made them express the female because a male should have been present. But when things changed they hermied more often. So I go with let them grow and thin the males... Less chance of getting screwed in the end with hermies.

Thanks T.H.C for your compliments, I appreciate your comments/feedback..... next time I would hope to have a larger sample and better control variables

Your prediction is very logical based on past experiences, but with this strain old-school logic doesn't necessarily apply.
I grew five of these Mexican seeds last winter and everyone thought at least 4 of 5 would be males as they were tall and thin, but turned out 4 of 5 were females.
Three of the female were about 5 foot tall, the runt was over 3 feet...I believe they are mostly sativa


@bryleetch ...your prediction could turn out correct but I'm still waiting on one plant to reveal its gender....go figure why one would be so far behind the others

One room has 2 females and 1 male, and the other room has 2 females and 1 TBD....I'm guessing it will become female as males typically mature first, but not always

Side by side pic from yesterday, from left to right M1, M2, M3, F1, F2, F3.......which one would you guess to be the male?

I'll post up full details on the final outcome once the last plant shows its gender

your not trying it with enough seeds.....all your readings 2/1 3/0 etc can all happen through chance there's not enough seeds to determine a true reading imo ..

 

[keysareme]

m3 for male.

 

[bradburry]

You cant rely on so few seeds for an accurate result

 

[ISK]

The last plant showed gender yesterday, waited until this morning to be 100% sure.

Male looking seeds in the female environment friendly room:
72 to 75 F, 60-65% RH, blue lights (6500K), 16/8 light cycle, GH Maxi-Gro (10-5-14)...which was grown in a bathroom with good ventilation and air circulation
2 females and 1 male (the male was M1)

Female looking seeds in the male environment friendly room
78 to 84 F, 20-30% RH, red lights (2700K), 20/4 light cycle, GH Maxi-Bloom (5-15-14)...which was grown in a closet with no ventilation and poor air circulation, as I needed to keep the door close to retain heat
3 females

Conclusion: hard to say with such a small number, but it is interesting that the room with such harsh environmental conditions could produce 3 females and the room with near perfect conditions does not.

So personally I believe the chart has merit but I also believe the environment has a huge factor in the plant's health and growth patterns....and also could influence the outcome of the gender

It would be more solid if you used more seeds ...........im sure if there was a way to determine the sex of a seed it would have been found by now and we wouldn't have to go to such extreme methods like silver spray to get the seed we all so dearly seek........the female




but nice try......remember me when your a millionaire lol
