First Attempt at Mainlining

I've just topped 2 x Critical Hog (T H Seeds), a Green Crack (H S O) and a Cheese (Dinafem) seedling.

I allowed the 5th real node to fully develop (as I am trying to root the tops as clones)
then I cut back to the 3rd (the 1st with 5 leaves).
After a few days under the lamp I will take off the foliage below the 3rd node
then start to train them to form the 'handlebars'.

As of yet I am unsure whether to try for 8 or just accept 4 main colas
It's my first try so I don't want to be too ambitious.

Here's some pictures.

Keep this updated, Im gonna follow, interested to see what the green crack does w/ main-lining. Never struck me as cola-dominant by the buds, but, I've never actually grown it.

Colour me interested. I've never tried mainlining and I've got some cheese beans sitting around somewhere, might be time for me to experiment if yours goes well

Id go for 8 how big is your space ? I just tried it and really enjoyed the outcome this was the second plant I'd ever grown and it was fairly easy
