I'm looking in the Developers>Storage>hrmp tab but I can't find the option to check the current minimum to create an HRMP channel. Thanks

You actually need to go to "Developer" > "Chain State" to check for the HRMP deposit. The function to call is activeConfig() under the configuration pallet. You'll see the hrmpSenderDeposit and the hrmpRecipientDeposit there, all in plancks:

Do note that there is an ongoing referendum now to lower the deposit substantially.
