Once the grow is complete, $1 is added to the server's available money for every script thread. This additive growth allows for rescuing a server even after it is emptied.
The multiplier scales exponentially with thread count, and its base depends on the server's security level and in inherent "growth" statistic that varies between different servers.
[getServerGrowth](./bitburner.ns.getservergrowth.md) can be used to check the inherent growth statistic of a server.
[growthAnalyze](./bitburner.ns.growthanalyze.md) can be used to determine the number of threads needed for a specified multiplicative portion of server growth.
To determine the effect of a single grow, obtain access to the Formulas API and use [formulas.hacking.growPercent](./bitburner.hackingformulas.growamount.md)<!-- -->, or invert [growthAnalyze](./bitburner.ns.growthanalyze.md)<!-- -->.
To determine how many threads are needed to return a server to max money, obtain access to the Formulas API and use [formulas.hacking.growThreads](./bitburner.hackingformulas.growthreads.md)<!-- -->, or [NS.growthAnalyze()](./bitburner.ns.growthanalyze.md) \*if\* the server will be at the same security in the future.
Like [hack](./bitburner.ns.hack.md)<!-- -->, `grow` can be called on any hackable server, regardless of where the script is running. Hackable servers are any servers not owned by the player.
The grow() command requires root access to the target server, but there is no required hacking level to run the command. It also raises the security level of the target server based on the number of threads. The security increase can be determined using [growthAnalyzeSecurity](./bitburner.ns.growthanalyzesecurity.md)<!-- -->.
