Any advice for growing Herer with a short veg ?

It will be a dense crop in soft pots of 7l. Six plants on an area of 50x50cm. From the soil to the led lamp the distance is approx. 70cm. Maybe 55cm is left for the plant itself. I have the option of putting on two nets (ScroG), I can do LST training, FIM or not train them at all. Apparently, Herer is growing fast and high. I wonder what method to choose and how many days of vegetation to give. Initially, I thought about 14 days, but I don't know if it's not too much.

Pics

Photos?
I haven't even poured the soil into pots yet, only in 3 weeks I will germinate seeds.

That’s not even 20” X 20”. I predict disappointment.

Why? I've grown it this way, it's just SoG.

Pics would be nice but the numbers show you don't have nearly enough height for a successful grow.

You have about 15cm (6") to work with until harvest

Sorry but I don't understand what you mean. I have 55cm for the plant itself, I usually leave at least 15cm from the plant to the lamp, at the end of flowering. Plants can withstand this without a problem.

This sounds like an interesting grow, you should do a journal. Hell you’ve got all of us interested and you haven’t even started yet.
So Jack Herer is your variety. I have a clone in veg right now. I grow a pretty mixed bag and I don’t find the Jack much different than the others, but never flowered one yet. I’m sure she‘s tall in flower though and fast like you said.
Me personally I run a net mostly and just let my plants grow through it and then FIM or bend the ones that get too close to the LEDs. 14 days of veg isn’t a whole lot, but if you’ve done this before, I’d be interested in seeing it.

I'll post photos when I start growing. I do not have photos from previous crops, besides, at that time I was not a very experienced breeder, so the results were not sensational and it was a long time ago. Recently, I wanted to return from AF to photoperoiodic varieties, but with a relatively fast cultivation time. I chose Herer because it is the best herb I have smoked so far. As far as I know, Herer likes to get a little less nitrogen than typical cannabis. But I don't really know how to provide it, because BioGrow has predetermined proportions of elements.

At the moment I wonder most whether with a 2 week veg it is better to start with LST or maybe rather do FIM
and whether to use the light 20/4 or 18/6.

If necessary, I have two nets that I can place at any height at any time of cultivation.

How would you even fit that many pots in that space. The entire idea sounds like something purposed by someone that's never grown before. I'd suggest one plant in that size space and increase the amount if you can be successful. GL

This is nothing extraordinary, the usual SoG type crop. SoG can be more or less tight/dense, depending on your preferences. 6 plants in this space is the maximum for this method. I have already grown in this way and there is nothing strange about it. The only problem is the height of my growing cabinet, but somehow I will manage by having two nets and doing LST.
