I am fine tuning my bottom feeding dunking. I don't like unknowns and how much to water is one of those things. And when you dunk your pots you cant' really measure how much you're watering because its invisible as it sucks water up from the bucket thru the holes in the bottom of the pots. You can control things though like how deep you dunk it and how long you hold it.
Anyway,
@slowandeasy got me in to bottom dunking seedlings in the solo cups to promote tap root depth. And I'm taking that to the next level and doing it with plants that are 25 days old and in their final 1g pots to try and promote a fast transition to flowering.
Being pretty much an undiagnosed OCD person that doesnt take any meds for the condition I'm free to be as OCD as I want to be. So bring it on.
I use a Control Wizard Accurate pH8 Soil pH & Moisture Meter (thanks to
@Waira for the rec - its a solid meter) as a way to understand how moist the pot is. I don't use it for testing PH any more. Its definitely much better than the $5 moisture meters. Its cool to see the readings change as the probe is pushed down to different depths in the pot. Once I have a pot that I think is as moist as I want it to be then I put the meter to the side. Then its time to weigh the pot. I picked up a nice postal scale for weighing my pots. It has a nice robust big platter I can put pots on and a there is a separate cord attached digital readout that I can easily read. Then I take all my pots and weigh them and then dunk them until they weigh what I want. That takes the guessing out of the equation. I don't like to rely on the knuckle test or just picking up the pots. Another nice thing about this is if I know I need to be more aggressive with the watering as
@slowandeasy suggested, I don't have to guess how that would work with how long and deep to dunk. I can just say I want to have the pots weigh another 100 grams and dial that in. Talk about accuracy. I love how accurate this is and how certain it is. Once I'm in full flower I will not be doing this thats for sure. Once in full flower I'll just be watering to run off N times per day. At some point the plants will be different sizes and weights so this won't work then, but I don't care any more by that stage of the grow.
