i have 5 seeds germinating,and just had a few questions
1.how long do they need to be to plant or recomended length ?
2.can i put the germinated seed in a rockwool cube even though its not gonna stand out of the cube ?
3.what should my light cycle be on the timer the plants are just 14days old 2 day ?
Thanx 4 Any Info !

You can plant the seed as soon as the taproot sprouts.

i wait like to the shells break then plants i use soil like it better and 18/6 i use not to use nut for 3-4 to there get bigger a least 2-3 weeks

ok, my question for this thread is this.
on average, how long dose it take for the seeds to sprout? mine have been in for a week and i am not seeing nothing?

i built a bubbleponic machine can a seed be placed in there to ?

Using the paper towel method and putting 2 dark plates on top of each other, mine sprouted in 3 days, started in 2 days. And my seeds are like a year old. Hope this helps.

Id also get a heating mat...not a heating pad that u'd pt on your back but a mat like aquarium reptile heat pad. this helps the warmth and humidity and helps the seeds break open.

how r u gonna come in my thread and ask questions ?WTF !
