REMOVING FAN LEAVES

Does removing fan leaves during flower improve bud quality and/or yield?

  • Yes! 100% verifiable fact backed by evidence that I can share right here!

  • Yes, because I read it once and loadsa growers do it so must be true

  • It does help, but only at very specific times in the flower cycle

  • Tucking away or under is better than removing

  • Its possible, but can't say for sure

  • Unlikely, since fan leaves are the solar panels of the plant

  • Absolutely not, totally against the accepted laws of botany... stop being silly

Flowers barely have any photosynthetic properties. They assimilate sugars for growth rather than produce them. This is why exposing them to light doesn't make any sense.

At the same time we know buds at the top of the plant nearest the light develop the best. Is this simply light exposure (sun ripening) or hormonal response (such as apical dominance), or something else??

This is the part nobody seems to be able to explain.

Most likely apical dominance (Christmas tree structure). It is the reason we top and train to redistribute auxins.

What about the leaves directly associated with that bud site? There's no correlation between the small leaves getting light and being able to provide direct energy from the light. Just wondering only thing I could ever explain for it is that the leaves directly attached the buds provide better energy to those bud sites. Again spit balling I've never been able to explain it I now the buds themselves don't have much photosynthesis power but what about the sugar leaves? Other leaves around it possibly?

Yeah I think the inference here is that photosynthate from sugar leaves travels less to the local Bud site and therefore is more energy efficient.

The less energy spent moving sugars around the more it may contribute to bud development at specific times.

That's my thought of the day, at least.

I'm also wanting to learn more about the proposal that larger/older fan leaves become energy competitors with buds and become undesirable. This makes practical sense, I just don't know if there's any solid science behind it relative to our plant and setups.

Ya i know it works but gotta know your plants and i know Indica's aren't a fan of it really. Idk im in same boat can't pin point why it works but ever since I been doing it instant boost in yield. Who knows wonder who will discover it
