4 out of 4 are males?

  1. So i have 4 plants growing and I decided to put them into preflowering. Well, not 100% sure as it's my first time doing this, but I think they are all males. I'm sorry if the pictures don't help (my camera can't seem to autoadjust really close to the plant). But if you can tell from the pics, are these males? Thanks

    And if they are all males, should I just cut them down right now and make canabutter and start over with 4 more? Or would it be worth it to veg them longer to get them bigger? Thanks again.
     
  2. You need to get better close-ups, can't tell from these pics. I see a few spots that could be male balls but just couldn't say without a photo right in on the flowers.

    You can get 4 out of 4 males, there is only a 6% chance of it happening but that's not impossible.

    If they are all males and you want to do something with them like make hash or butter then definitely grow them out. The only reason not to would be because you don't want to pollinate females. If you do grow out males you will have to clean the grow space very thoroughly if you ever want to grow unpollinated females in there, the pollen from these males could be on every surface in there and continue swirling around for a long time, waiting for a female bud to pollinate.
     
  3. thanks, those are the best pics i can get with my cam. I'll let them go under 12/12 for a few more days until i'm 100% sure myself.
     
  4. Does your camera have a macro setting? I just really can't tell by the pics. Is it a cheap shitty cam? if it isnt it probably has a little flower button to turn on macro.
     
  5. *Raises hand*

    Point of order. The above is a common misconception.

    A seed has a 50% chance of being male, it does not influence the seed in the pot next to it, which also has a 50% chance of being male.

    Plant as many seeds as you like, and theres a 50% chance of them all being male.

    That's put a downer on your day, eh?
     
  6. yes there is a macro button... just have to figure out what to do after i turn it on.

    and for chances it's... 1/2 * 1/2 * 1/2 * 1/2 = 1/16 chance all are male? which is 6% like toasty said.
     
  7. +rep for j00. Rabiez if that were true I might have to shoot someone, but it isn't.:hello:
     
  8. ok, so i found out macro is for close distances. So here are some reshots with macro on.

    hope this helps.
     
  9. They look male flower sacks to me, although I can't really see in the 2nd photo. Bad luck dude, I'm gutted for you.
     
  10. It is a 1/16th chance that all the plants are male.

    Assuming basic statistics, and not including grow conditions and other variables that affect sex, each plant has a 50% chance to be male, 50% to be female. So for the first plant, there is a 50%, or 1/2 chance, that the plant will be male. For the second plant, there is also a 50%, or 1/2 chance of getting a male. However, for both to be male, there is a 1/2 chance of getting a male on the first one, and 1/2 of that to get a male on the second as well. Ths continues for 4 plants.

    Long story short : 1/2 * 1/2 *1/2 *1/2 = 1/16 chance for 4 males
     
  11. It won't hurt to let them go longer and as far as I can tell the only one that looks like it could be male is P4. Give them 3-4 moredays and you should be able to tell better. I'll bet you have at least 2 if not 3 females.

  12. I thought the first pic had the startings of female hairs, not sure about the others:eek:
     
  13. *Shuffles feet*

    Look, I'm right, and that's all there is to it!

    My extensive experience with NASA* sets me up perfectly to answer complex scientific calculations such as these.

    Whilst I realise some of you may not like being wrong, I think it was childish and petty to use your influence to get sites like math.com, wikipedia, and google answers to change their content, just to make me appear as if I was talking out of my backside.

    I mean...I'd have to have been pretty mashed, and probably a little drunk to write something like that when there was all this evidence to the contrary just hanging about on the web, wouldn't I?

  14. It can happen. (BAD) luck of the draw.
     
  15. Evidently a high ph (7.0+) can influence the sex of the plant to being male:D
     

  16. i'll test the ph lvl sometime today or tomorow.
     
  17. Sex is predetermined. Ask the seed banks who sell feminised seeds.
     
  18. Park the ego at the door, dude. Sorry, but there still is a 1 in 16 chance (6%) that 4 out of 4 will be male. There are 16 possible combinations:
    MMMM
    MMMF
    MMFM
    MFMM
    FMMM
    MMFF
    MFMF
    MFFM
    FMFM
    FFMM
    FMMF
    FFFM
    FFMF
    FMFF
    MFFF
    FFFF

    Only one of these combinations yields all male. In fact, the odds of getting any one of these specific combinations is 1 in 16. But the odds of getting, say, 1 female out of four are higher because we aren't concerned with which particular seed will be female -- we don't care if its the 1st, 2nd, 3rd, or 4th seed that is the one female as long as there is one. There are four combinations that yield one female seed so the odds of getting one female are 4/16 = 25%. Of course, we would like all four seeds to be female, but the odds of that are also 1 in 16 (only one possible combination, FFFF).

    It is true that the odds of one seed do not influence the odds of the other seed. But the odds compound when you are calculating for specific combinations.

    For example, if you flip a coin 9 times and get nine heads in a row, the 10th flip still has 50/50 odds to it. The odds of getting 10 heads in a row is 1 in 1,024, but by getting 9 heads in a row beforehand you've already achieved something for which the odds are 1 in 512, and the tenth flip doubles the odds on top of that.
     
  19. Tell that to the gamblers round the roulette wheel!!!!

    Nice post toasty, well explained. +rep
     

  20. WHOOOOSH!
