If you will finalize all the details, you can't appear more than 1 time per week. To this aim I chose this system. A full tank will suffice to 1-2 weeks depending on the size of plants and daily humidity + coconut can stand without watering + 2-3 days.
More about salting. Most importantly is not pour from the top. Plants mainly feed from the pallet. If the ppm in the pallet is lower than in the tank it means everything is absorbed. If the ppm is above, it's necessary to reduce the concentration.
Another such trick - I do the compote in the tank strongly acidic 4.2-4.5, when I pour to the pallet it's diluted to 5.5. And when the plant drinks the ppm has time to rise to a maximum of 6.2. We can say it's the ideal environment for the absorption of the necessary elements😏
