Hey,

I must say that I am not a very experienced grower but here is my 2 pence on this. I hope it works for you.

The height of the light, intensity, determines the node lengths. In some cases it can be genetics, i.e. Indicia strains. I am growing an unusually bushy plant out of 9.

It must be some old school Indicia strain ! It looks awesome and half the height of the other plants no matter what I do.

You can check my grow here. Ill take more detailed photos of the bushy plant. I had it on the edge and it didn't stretch much at all. Strange one. Super stumpy and bushy.

I moved it into the middle of 9 plants as it will stay short giving more light coverage to the surrounding plants.

You can see my LED grow here. The plants look awesome, just amazing growth. LED LOGGER

The nodes are the spaces between the 2 leaves. They grow 2 x 2 x 2 leaves etc.. until bloom where its 1 x 1 x 1 leaves. (colas)

You can make the plant less bushy by raising the light therefore making the plant stretch towards the light. The lower the light, higher intensity, the stumpier it becomes.

Try to get 1.5 inches between the nodes. No less than an inch. This will give space for new shoots from the stem.

Also when bloom comes watch the colas length. you will want the same on each, about 1 - 1.5 inches between leaf points.

I hope this helps.

Take care
