So you’re a DWC nut with a container full of water with bubbles bursting above the waterline and you tried to keep jiffy pellets moist from underneath without a top drip and you just can’t seem to get all the pellets moist enough or they just stay too moist.
You can’t leave the bottom of a jiffy pellet slightly dipped in the water below...or can you?
If you’re using the extra large jiffy pellets (the ones that expand to 2” diameter when wet) you most certainly can drop a germinated seed into this slightly immersed jiffy pellet (in a DWC container) and expect excellent results.
There’s a knack to it but absolutely no learning curve.
Anybody that tells you you can’t is either lying or did it incorrectly.
Here’s how it’s done:
Get a 2” sch 40 pvc dwv male adapter (must be this part and not a regular male adapter) and a jumbo jiffy pellet. Pre-expand the jiffy pellet. Place the jiffy pellet into the dwv adapter. Cut a hole in your container lid with a hole saw so that it’s snug but your able to pull it out with minimal effort.
This part is crucial...make sure half of the pellet is above the lid line. Make sure only about 1/8” of the bottom of the jiffy pellet is touching water. Have an oscillating fan on low setting blow air over the pellet while it resides in the container. Pop your seed in.
I’ll explain why this works.
The top half of the jiffy is drying out above the lid line with the help of the oscillating fan while the lower half is soaking wet. This makes the top half of the jiffy still wet but not so wet that the seedling won’t sprout.
The tap root of the seedling will exit the side of the jiffy pellet just below the threaded portion of the dwv adapter. Yes, it is avoiding the super moist lower half of the pellet. Them taproots sure are smart! Just make sure you have bubbles bursting above the waterline as usual.

Great idea! I'd be worried about a full-sized fan blowing on sprouts though. You have to be really careful about that because the wind can draw too much perspiration from the leaves, and dry them out. Wind isn't recommended for little ones. Given your idea, I would lean more towards using 80mm DC fans (PC fans) with a low output power supply, so that the breeze is very minimal. I would then angle the fan down so that it points more towards the jiffy pot, and not the sprout. 5vdc cell phone chargers would work well for lower fan speeds, or a 12vdc with multiple fans. PC fans can be ordered in bulk from Chinese distributers for cheap.
