Tmux split window vertically and define top pane's height

I have a small script which turns my terminal into a monitoring view for the GPU. The nvidia-smi -l 1 command I run in one of the panes requires it to be a certain height though, which I can calculate based on the number of GPU processes using 

smi_processes=$(nvidia-smi pmon -c 1 | wc -l)
smi_height=$((${smi_processes} + 3))

(Have not done proper calculations yet.) I want this process to run in the top right pane though, but don't know how I can assign that pane a certain height. I can define the height of the bottom right pane just fine. This is my current script:

smi_processes=$(nvidia-smi pmon -c 1 | wc -l)
smi_height=$((${smi_processes} + 3))
tmux \
    new-session  'htop' \; \
    split-window -h 'nvidia-smi -l 1' \; \
    split-window -v \; \
    split-window -v 'xdotool key F11'\; \

This will split the right two panes evenly and then set the terminal to full screen. I can define the bottom pane's height with split-window -v -l [height] \; \ but this would mean the top window will have different heights on different size monitors, or different terminal settings. I tried spawning the process in the bottom pane, sizing it and then swapping the pane up using swap-pane -U, but the size is linked to the bottom pane. TL;DR: How can I have the top right pane be a certain height, and the bottom right pane to take up the rest of the space?

Thanks in advance!

Fixed it by moving the fullscreen command and by using resize-pane -y and select-pane:

smi_processes=$(nvidia-smi pmon -c 1 | wc -l)
smi_height=$((${smi_processes} + 5))
tmux \
    new-session  'htop' \; \
    split-window -h 'nvidia-smi -l 1' \; \
    split-window -v \; \
    split-window -v 'xdotool key F11'\; \
    select-pane -t 1 \; \
    resize-pane -y $smi_height \; \
    select-pane -t 2 \; \
