How do you balance two frame boxes in the same page?

Question

I have a problem with fitting two flowcharts encased in frame boxes to fit nicely within a single page and how do you add a little more bottom space to the box frame?

  block/.style = {
    rectangle,
    draw,
    text width=5em,
    text centered,
    minimum width=3cm,
    minimum height=1cm,
    rounded corners,
  },
  line/.style = {
    draw,
    -latex',
  },
  text/.style = {textwidth = 3em
  },
    longblock/.style = {
    rectangle,
    draw,
    text width=10em,
    text centered,

Also it's recommended that you also include a screenshot of the current output, and also a sketch of what you want. — user202729, Dec 26 '21 at 02:38
Also it might be better to use tcolorbox instead of TikZ e.g. https://tex.stackexchange.com/questions/552335/how-create-these-boxes-style — user202729, Dec 26 '21 at 02:40
Actually also not that one (okay, reading the documentation (LaTeX2e unofficial reference manual) it's controlled by one of the \...fraction parameters), but still, if you only need the figures on the page then you don't need that float environment. — user202729, Dec 26 '21 at 02:59
Does this answer your question? How to put two figures in the same page? — user202729, Dec 26 '21 at 03:06

I would put both images to one float with position options [p]. - Nesting tikz image in tikz image is not good idea, you can experiences unexpected problems (aligning of images)
Defining new commands for inserting images doesn't shorten code or make it more clear, I would rather insert image directly in float environment
Using additional tikz libraries can significant shorten code, make it more concise and clear:

Addendum: For the flowchart asked in your comment:

please always put your ask in question, that it can be (better) visible to all site members
you can draw this flowchart on the same way as are drawn in above MWE, so its code can be:

    \begin{tikzpicture}[FC] 
    \begin{scope}[nodes={block, on chain, join=by line}]
\node (bl1) {Hạt giống SNC}; 
\node (bl2) {Hạt giống \\ NC}; 
\node (bl3) {Hạt giống XN}; 
    \end{scope}
\node [below right = of bl3] (bl4) {Sản xuất đại trà}; 
\path [line] (bl3) |- (bl4); 
    \end{tikzpicture}

however, your document preamble had to have the content of above MWE's preamble too.

@Anon, on the same way as is done in my answer. See addendum. — Zarko, Dec 26 '21 at 12:36
What code do you use to make the light grey portion covering the flowchart smaller? — Adrik Ivanov, Dec 28 '21 at 02:26
@Anon, all used code is in the answer. All modes size are the same as you defined in your MWE. Defined are as part of nodes styles collected in \tikzset. — Zarko, Dec 28 '21 at 07:54

How do you balance two frame boxes in the same page?
