Am I doing this right?

This is the first time I have tried training my babies. I'm letting them grow and spreading them around through the holes as the branches get long enough. When do I start to flower?

Your pictures are weeeee tiny. JAS

The picture is tiny so it's hard to judge how tall they are. If your doing a Sog I'd switch now and raise your trellis a bit. If you want the full on Scrog I'd say raise it quite a bit (they look small from the pics) and do some more training.

It looks like your in a tent, me too.

Disclaimer = I've never used a net

but my understanding of the idea is to train under the net, and then cull anything that won't see light.

So..... Depending on how much light you have, you should adjust accordingly.

I still say cut the lower growth or rebend what you have poking through now.

Also, props on the baby gate. I didn't notice it at first.

The baby gate was the easiest thing I could think of

When do I turn it to 12 12? It's approx 75% covered now

What size light are you using? Anticipate the stretch.

400 meh for now. Swapping to 400 hps for flower

Fire it up and after a week or two adjust it accordingly.

I would still cut some lower growth out, then give it a week to recoup before the switch. A lot of that undergrowth will never see light.
