Managing 9 different strains in in one tent

So I have a 4x4x6.5ft tent and I want to grow 9 different strains some sativa, some hybrid, some indica. Ill be using a NFT system that I'm currently in the process of building.

Obviously if I dont train them I'm going to have a really uneven canopy but as long as I train and top the sativas more will keeping the canopy even be difficult? I'm also worried that with all the training and topping of the sativas the indicas will be crowded out?

Put the sativa to the back, indicas to the front is what I did and keep topping, I had a headband/sour kush one time and would not stop growing and constantly topped lol

I grow 4-6 strains every cycle. I always put a certain strain in the back cause no matter how much training, she always towers over my other plants. and 1 plant grows slow, so she gets put in the middle.

This isn't the answer you're looking for, but grow 1 strain instead of 9.

Imo, 2 for that area is too many strains.

Or you can do do 1 strain at a time. Will help with the even canopy and maximize yield. You can easily meet the nutrient needs of 1 strain without sacrificing the needs of others.

You know, sometimes you have to grow
A bunch of different strains FIRST, so then you know what strain you wanna clone the shit out of for a while
I have 2000w's just for pheno hunting from seeds. It's definitely not As easy as 1 strain, but it is necessary for my happiness
