The very best way to get any grow started....
Seeds: using a UVA Bulb, yes a UVA BULSB. Take a small plastic container with a plastic grill of some sort that fits into container. Place grill so it has a slope resting at bottom. Place a water soaked paper towel, folded to fit over grill.
Now, if your smart, use a product at kelp4less.com, the Root enhancer there is above board.
Now, soak seeds for a day, keep in dark area.
Now, place seeds on higher side of grill. Top of container should not be sealed! Place seed mat underneath with a short gap between container and pad (so they will not fry.)
Immediately use UV light. The UVB Bulb should be in to 60-80watt at 385 nm area so you do not need to be so close, 40 watt might fry because it simply cannot get close enough!
Buy a bloody LUX meter for pete sake!
Now lower until you reach 1150LUX. Run for 15 minutes only! You see the magic number is 385, which is also.....PAR. Multiply PAR by 3.05 and you get 1150lux.
May have to open container when doing so, might get too hot...
Then they stay completely dark for another 23 hours and 45 minutes.
If using kelp4less, will pop in 24-48hrs! Second day, same thing 15 minutes. Keep at 79-81°, Place seed pad thermometer inside container, on grill.
You could continue on for days like that, they will continue growing.
After that, plant in 4" pots, not for plugs, they get too long!
Using a 315CMH at 4k lux with humidity at 75RH at 78-81° for pots
