Mesh Network? Need Pointers

Using Arduino Programming Questions
1

I have nrf24l01 transcievers and Arduino Unos, and I am trying to get a system where my Arduino at my computer has 2 children that collect data from 5 children each. So there would be 10 Arduinos reading sensor values, 5 on moisture probe and 5 on temp sensor (all in different places). The 5 moisture would send values to another Arduino to collect them all, and the temo Arduinos would do the same with a different one. These 2 Arduinos would then send to 1 master that collects all 10 values. I looked it up and it seems like a mesh network would allow this from TMRh20's library. I successfully made connection from one acting as a transmitter and one as a receiver.

transmitter code:

#include <SPI.h>  
#include "RF24.h"

RF24 myRadio (7, 8);
byte addresses[][6] = {"0"};

struct package
{
  int id=1;
  float moisture;
};


typedef struct package Package;
Package data;


void setup()
{
  Serial.begin(9600);
  delay(1000);
  myRadio.begin();  
  myRadio.setChannel(115); 
  myRadio.setPALevel(RF24_PA_MAX);
  myRadio.setDataRate( RF24_250KBPS ) ; 
  myRadio.openWritingPipe( addresses[0]);
  delay(1000);
}

void loop()
{
  myRadio.write(&data, sizeof(data)); 

  Serial.println(analogRead(A0));
  data.moisture = analogRead(A0);
}

receiver code:

#include <SPI.h>  
#include "RF24.h" 

RF24 myRadio (7, 8); 
struct package
{
  int id=0;
  float moisture;
};

byte addresses[][6] = {"0"}; 



typedef struct package Package;
Package data;
int row = 0;
int x = 0;
void setup() 
{
  Serial.begin(9600);
  delay(1000);
  Serial.println("CLEARDATA");
  Serial.println("LABEL,Time,Moisture");
  Serial.println("RESETTIMER");
  myRadio.begin(); 
  myRadio.setChannel(115); 
  myRadio.setPALevel(RF24_PA_MAX);
  myRadio.setDataRate( RF24_250KBPS ) ; 
  myRadio.openReadingPipe(1, addresses[0]);
  myRadio.startListening();
}


void loop()  
{

  if ( myRadio.available()) 
  {
    while (myRadio.available())
    {
      myRadio.read( &data, sizeof(data) );
    }
     Serial.print("DATA,TIME,");
  Serial.println((-10.32 * (log(data.moisture) / log(2.718)) + 72.66));
  row++;
  x++;
  if (row > 60)
  {Serial.println("CLEARDATA");
  Serial.println("ROW,SET,2");  
  row = 0;}
  }

}

I have read through the entire library on TMRh20, but there is not great description of what does what and how to put it in the code. I have spent hours each day for over a week and I have gotten nowhere at all, so I figured I'd ask people who know a lot about this.

It would be greatly appreciated if anyone could help with me setting up a system that accomplishes my mission. It would also help if you know if a mesh network will or won't work doing this and if there is a more efficient way to do this than a mesh network.
