Seedling question

Does anyone have any experience growing Greenhouse Seeds Super Lemon Haze?

Specifically how long should they take to sprout? I soaked them in water and planted in rapid rooters 6 days ago, still nothing.

I know sativas can take longer than indicas to pop but Im starting to worry they never will.

Yes I have
and it is best to wait another week but not all seeds are viable

Thanks for your input.

I have a lot and always standard 24-48 hrs

I always use rapid rooters and my seeds sprout within 3-4 days every time - and I never pre-soak.
10 for 10 last time.

So I broke open the rooters and found the seeds, they were very dark almost black and twice as large as when I put them in...

Does that indicate a specific issue?

I decided to try 2 more with the paper towel method.

Try drop seeds in cup of filtered water for few days. Once u see tap root plant in basic soil like fox farm ocean forest. Leave light on 24hrs until seeds sprout Keep spraying with mister water bottle to keep pots Moist not soaked.

Second attempt also failed, waited until their were lil taproots when in the paper towel, transferred them to cubes... Then nothing. This is driving me nuts. Could my heating mat be cooking them? Or are the cubes too moist for SLH? I am thinking of just putting them direct into coco after soaking them for 24 hours... Anyone who has grown SLH successfully, what method do you use?

Do you use a heat mat under the tray? Or humidity dome?

Never. I place the seeds in the rapid rooters and stick them in a drawer.
Seeds sprout fine at room temperature and humidity domes are for clones, not seeds.

What is your heating mat set to? How wet were the rooters and how long did you soak the seeds for? How wet was the paper towel?

Dont keep them too wet

I put mine on top of the cable tv box
You are probably drowning them if you get tap roots and fail

Oh it can be done. I've seen it first hand. Not mine but a friend that wouldn't listen to my advice.

I suppose if you saturated it and didn't squeeze out the excess, and kept it saturated - you could drown the seed.
But who is that stupid?

New growers.. Like the people who don't have any growing experience at all? You do know what section of the forum this is right?
