Stipules, what are they?


#1

As a first time indoor grower im seeing a large amount of stipules on my plants. They have been on the 12-12 light cycle now for 4 days. Is these stipules the beginning of the buds?


#2

I think you are seeing the calyx of the pistil forming, so the correct term is pistil, not stipule.


#3

So whats the difference between the pistil and stipule?


#4

I’m not a botanist, but I believe it has something to do with the difference in leaf parts versus flower parts.


#5

I know every mmj plant, either male or female, has stipules. Male plants will only have stipules which is how you can tell them apart early on.

Still a great question cause I’m unsure what their actually for as well.

Males have staminates, again, stipules are parts that lead to leaves, not to flowers, male flowers(stamen) or female flowers(pistils). Stipules are parts related to leaves, not flowers.
