I found this method online before I started my last germination and it worked AMAZINGLY well, all popped within 2-5 days:
"REQUIRED PARTS
1. A 2 -3 gallon clear plastic
storage tub ($3)M
2. A smaller, sandwhich sized tupperware plastic box ($2)
3. A
cleaning size antibacterial sponge, ($2)
4. A self setting aquarium heater ($7 at WalMart)
5. An aquarium thermometer, ($1.50)
The larger tub is fillled 1/2 way with water and the aquarium heater is placed in the larger tup and allowed to heat the water to a temp of 76 degrees, confirmed by your aquarium thermometer which is also in the larger tub. The little preset heater is set for 76 degrees. It seems thats the temp for fish as well.
The sponge is cut in half or buy 2 and the seeds will be placed in between the 2 sponges. The sponge unlike paper towels, allows air to the seed and keeps water away from them. The seeds are subjected to moisture between the sponges but not water. The sponges should be saturated but not dripping.
The sponges go in the sandwhich tupperware box and the top placed on it and then it is place floating in the 76 degree water. In short order, the sponges and the moistrue in the sponges are also at 76 and thats where the seeds are at.
The consitent
temperature, water and air will quickly germinate any viable seed placed in it. With this method, 90% of indica seeds will germinate and pop within 18 hrs and all will have popped within 24. Long
flowering equatorial sativa's which are very hard and moisture resistant can take up to 72 hrs but most will pop within 48.
This little contraption is the most important device i own. I can buy single seeds and pop them all day long."
