Germinated in a clean 100% cotton washcloth. I NEVER use paper towels. You never know what additives are in them.
As soon as the seed caps split, I put them in small 1" rockwool cubes. There was one "buckethead" but a pair of tweezers fixed that.
Rockwool cubes were put in a generic dome and checked daily until I saw roots penetrating the rockwool.
I actually germinated 6 seeds. All 6 worked and I kept 2 in the dome just in case. Didn't need them.
Once roots were breaking through the rockwool, they went into the buckets. I'm using black 5 gallon buckets with 6" net tops.
Put about a 1" to 2" layer of hydro ton on the bottom, sat the cube in the center and covered the rest with more hydro ton to cover and stabilize. (Rinse your hydro ton)
Exactly 4 gallons of water just barely submerged the bottom of the net which allowed the hydro ton to wick up just enough solution to hydrate the roots.
I have to point out that I'm using ROUND air stones. They are 4 inches in diameter, 3/4" thick, and perfectly disperse the bubbles in a round 5 gallon bucket.
I would look to get that room a bit warmer for sure, You will end up with some very nice dense caked buds off these ladies with these temps for sure! only problem will be somewhat losing out on size, If we get a bit warmer in there we can get the best of both worlds. Keep up the great work friend
Looks good man. Your lights on temps are a little low. 72 at this stage of development will cause slower growth and smaller bud site formations. The first 4 to 6 weeks high 70s to low 80s will help make much larger buds. after that lower temps of 77 and 10 degrees less at night will help form them up nice and dense and you will get much more resin production. Keep up the good work ! Also look into getting a PAR meter and a thermal gun to read your plant tops and get the maximum potential from your equipment.
