Bought a bag of cheap seedy bud a while ago and must have collected 50-100 seeds. So this spring I decided to germinate 6 of them for a simple outdoor grow. I was expecting a couple to die and 1/2 of them to be male resulting in 1 or 2 decent female plants. However, all 6 are doing well and all of the plants appear to be females! Can someone do the math to tell me what the chances of being this lucky are? Assuming a 50/50 ratio of male/female what is the statistical chance of drawing 6 female seeds at random? I'm wondering if the previous grower had a hermie that subsequently pollenated his grow resulting in feminized seeds? Having all 6 turn out to be females seems a little too lucky to be just random chance.
Found an online calculator. 1/64th or 1.56% chance. Sounds pretty damn lucky to me and I think there is a good chance I have a bunch a feminized seeds. Hopefully they've got good genetics to go with it!
Definitely lucky. How is the math wrong tho? I used an online calculator so it's not like I care but it makes sense if you think of it as below. 1 plant female = 50% 2 plants all female = 25% 3 plants all female = 12.5% 4 plants all female = 6.25% 5 plants all female = 3.125% 6 plants all female = 1.5625% Please do show the proper way to calculate this if it is indeed wrong.
Your think it would make sense but there a different ways of calculating the correct answer depending on the relationship of the two variables.You start with 100 seeds being 50/50, your odds are 50%Now once you remove that first one, then your odds become less in favor of whichever you drew.Once you pick your first seed there's no longer a 50/50 chance, it would be 50/49 Mathematically this would look like this if you wrote it out.(1/100) + (1/99) + (1/98) + (1/97) + (1/96) + (1/95) = 6.15%How you did it would make sense if the one seed replenished itself and there were 100 no matter how many you removed
100% chance you have herm stock ..... bag seed that only produces females is not something to brag about. sorry.
What gave you the idea I was bragging? Just pleasantly surprised. As for bagseed. C'mon, you know as well as I do that it's a complete gamble. Could be poor genetics, could be excellent. Automatically assuming it's poor genetics just because I got it out of a bag is really short sighted and reeks of something a seedbank would say. Most likely it's nothing special but won't know for sure until it's harvest time. There is a reason that this is a low effort outdoor grow.
There are a few reasons: 1) I already had the seeds. 2) I've wanted to do a low effort outdoor grow for a while now to see what the results would be. Free seeds is a great way to do this. I literally have less than $20 invested. If I'm happy with the results I'll do it again next year with better seeds. 3) I want to know where you are getting your seeds from. Everywhere I've looked a 5 pack of good feminized seeds goes for around $100. 4) I simply cannot throw out these seeds without at least giving them a try. It's not in me.
Making the initial assumption that you will get 50 females out of the 100 seeds is not correct - that only works as the number of seeds approaches infinity. It should be calculated the same way as if tossing a coin, where every seed theoretically has a 50/50 chance of being female.
Check out Herbies for seeds too. They throw in freebies on every order. I ordered 15 top of the line fem seeds and got 6 fem and 10 regular seeds free. 31 seeds for about 150, delivered.
Yup, those seeds came from a hermie plant, that's why they are all female. Chances are, they will all hermie on you as well.
I don't care what anyone says bag seeds can turn out good bud way better bud than the bag u got it out of Sent from my XT907 using Grasscity Forum mobile app
no one is saying bagseeds are bad......or that you cannot yield some dank as shit. ( hell I'd hope you're able to do better then the numb nuts who either forgot to take out the males or caused stamens to pop) what we're saying is that if you use bag seeds, and you get 100% fems, you're very likely growing hermies. mathematically speaking he probability of herm seeds is much higher, then em all being females
Update: You guys were right. I had to cut down a plant as it turned out to be a hermie. It had flowered as I wasn't watching it (thought it was a female). But luckily I think I caught it soon enough. Only about 5 or so pods had opened. I may find the odd seed on my other plants but shouldn't be too bad. 1 hermie out of 6 plants so far. I don't think the other plants are hermies as I don't see any signs of it on them - but will keep checking and will update the thread if I find more.
