ive just had my first smoke of the day so bear with me on this... I have been collecting various seeds over the last year, i moved house and my carefully selected seeds got mixed up. i was only able to sprout 4 of my first 20. but already even in this early stage i can see there are clearly 2 different strains that have sprouted, 2 of each which is nice. So i will use my 2 as an example because there is quite a contrast. Strain A - 2 weeks old and already about 4-5 mm taller than SB - light/bright greener than grass green - leaves come to steep point at the tip. fins on leaves are regular but very rough and jagged all the way along. Strain B - distinctively shorter than SA - dark bush like green colour - tips of the leaves come into a semi-circular curve. fins on the leaves are regular and even, almost as if the leaves are a smooth oval shape opposed to the spikey nature of SA (I have pictures to illustrate if you aren't sure what i'm on about.) i enjoy studying mushrooms and other fungi in terms of looking at what subtle (and not so subtle) differences in the patterns and shapes you find can mean about that plant. so based on my examples or please share others what can we tell about a cannabis plant of unknown origin? i understand height usually indicates a sativa dominant strain but i am particularly interested in what you can learn from the leaves in terms of pattern/shape and colour?
