Yes sir chronicis, my question was about exactly how much water...
I know how much my ladies need...at least I thought I did, until I saw this stupid rule of thumb. I was just asking if I was off or the video was off. From the answers here, it seems the video is off and that equation is low on water and will dry out most plants.
I know the video that you've seen. Just ignore the video, its pretty impossible to have a "regular/daily" watering cycle when the plant uses different amount of water/nutes depending on the size of the plant, temperature etc. The best bet is just to use the weight/dryness of the pot as the measurement when to water.
