Plant growth differs

Both are nirvana ice germinated at the same time but they are growing completely different.one way thinner then other Is this common?

best answer was given by brick top in a similar thread...see if I can find it....but basically you have two phenotypes...one carries more characteristics of the male plant (father) and one of the female (mother), so you got two flavors outa one strain....lol

Plants will have some variations because of the gene types being used to create that strain. The less stable the strain the more variation you'll get or the different pheno types you'll get. like one plant will represent the mother and some will look like the father. Depends really on how long the strain has been developed.
