A comparison between insect-pollinated and wind-pollinated flowers

Similarities

  • large, conspicuous petals, often with guide-lines
  • often strongly scented
  • often have nectaries at the base of petals
  • anthers inside flower, where insect has to brush past them to reach nectar
  • stigma inside flower, where insect has to brush past it to reach nectar
  • sticky or spiky pollen grains, which stick to insects
  • quite large quantities of pollen made, because some will be eaten or will be delivered to the wrong kind of flower

Differences

  • small, inconspicuous petals, or no petals at all
  • no scent
  • no nectaries
  • anthers dangling outside the flower, where they catch the wind
  • stigmas large and feathery and dangling outside the flower, where pollen in the air may land on it
  • smooth, light pollen, which can be blown in the wind
  • very late quantities of pollen made, because most will be blown away and lost

Overall comparison

Insect-pollinated flowers on the left. Wind-pollinated flowers on the right.

I agree that when it comes to growing weed, it can be a challenge to find high-quality seeds, but I decided to buy autoflowering ones, and I can tell you that it turned out to be a great solution for me. I highly recommend you check them out as well, and you can click here and decide whether it's for you or not because there's all the necessary info.
