I got curious last night as I watered my babies in their solo/beer cups, and after slowly watering to the point of run off, I weighed my cup. I was shocked to learn that the previous light as a feather cup now weighed almost a pound, or 418 grams to be exact.
I was shocked, so I decided to find out how much water I just added. I carefully weighed a cup full of dry soil and took that off of the total. I then weighed out the resulting 320 grams of water.
Here is a picture of how much water that really is:
That my friends, is a lot of water to be suspended in the soil. Now it is clear how the micro life moves around inside of the root ball. It really makes a difference to water completely and thoroughly.
Weighing these beer cups to find out how much water has been used is also a very valuable tool in the veg tent. When I am baked and watering, sometimes the "lift" method is less than accurate. Weighing takes away any doubts as to when it is time to water and which plants are using more water than others. For example, my most robust plant just used 63 grams of water in the last 18 hours, compared to my smallest plant which only used 20 grams in the same period of time. Being able to see exactly what is happening inside of that cup, knowing which plants are using or not using water, is a huge advantage in accurately judging when to water and when to let it ride, and to recognize when a problem is occurring.
