    Transpiration :-)

    1. If a plant is close to wilting is it correct to assume it cannot open its stomata in response to high humidity? 2. How can low humidity cause stomata to close when the plants highly hydrated state causes strong enough osmotic pressure on the guard cells to keep them open? 3. Does...

    Still waiting for an answer on those purple colours??

    Seems like there is no real agreement as to why plants turn purple here. I know if i give less than stellar conditions and hamper transpiration i see build up on stems and petiols and then if i revert back to perfect conditions the purple fades away. Basically i can take the same strain and make...

    Anthocyanins purple stems

    Ive heard all that mumbo jumbo about purple genetics and stems but then i read a lot of intresting articles on the use of anthocyanins in osmoregulation (one a stoner myth the other a factual study). Multiple experiments show anthocyanins (purple) to be linked to stress, trees do not show their...

    Serated vs round leaves?

    *Boundary layer* – The *boundary layer* is a thin layer of still air hugging the surface of the *leaf*. This layer ... I couldnt find the reason why leaves are serated as oppose to round but i would think that the serations provide better control of the leaf boundry layer over round edges...

    Disbuting growing method...

    When i first stuck a seed in a 1.5" rockwool cube the words "Keep it moist not wet" resounded from every thread. The general practice seemed to be- Saturate the cube then flick it like your flicking the water out of a paint brush before planting seed. I dispute this as that led to too much air...
