Plants transpire the same amount of water they absorb. So however much they absorb, is the amount you need to remove with your dehumidifier. e.g. If you start with 100 litres in your tank, then 24 hours later it's 80 litres, plants have used 20 litres. So you need to remove 20 litres each day. A Quest 70 is ideal!
