Depends on the strain and pheno of that individual plant, usually a Sativa will stretch more and some people will start with the lights further from the plant to get a higher stretch (you saw in my soil pictures the stretch on those and the light was less than half a foot from them as seedlings, as soon as I moved them under the 80w cfl the distance between nodes decreased. It is how you want them to grow and your setup that can also determine stretch to a degree on top of their genetics.That kerala is not stretching at all lol Idk if that's a good thing or not haha
You can also see from greenthumbs grow, he is using a T5 light from the looks of it, but if you notice the difference in gap between the buckets and where the light is you have around 2 foot of space, as seedlings with that much space your going to start stretching the plant much more than if you were to put them 4-8inches from the light. He is doing great and in no way is stretch a bad thing just a fact, distance from light and strain equates to how much stretch
see the inernodes (distance between each new leaf growth) in the picture, there is up to an inch or more between them, which is fine but if you were in a reduced height space you would drop the light closer and encourage as short internoding as possible.
This is why outdoors if you let a Cannabis plant naturally develop you would have 20ft high monsters, but you can also see 1metre short bushes, its all based on how you train the plant to grow.
