Seeds in rockwool...

So, I just happened to find a whole bunch of rock wool under my couch when I was cleaning. I soaked it in ph'd water over night. I have a bunch of bagseeds I soaked overnight too.

Do I just drop 'em down in the hole punched in the rock wool? Do I pinch the hole closed like I would for a clone?

How long can I keep seedlings in just rock wool before I transplant them?

Should I pour a bit of water in the bottom of the bin with my cubes in it?

After they grow and I pick out the keepers, I'm gonna move them to solo cups full of perilite and attempt a SOG style thing I guess.

THANKS!

I use the small rockwool or jiffy starter cubes. I would use spring water and soak the cubes. They already have a hole, to drop the seed into. I keep the cubes in small tupperware container(don't cover), in a dark cool spot. Check the cubes to keep them moist. Don't over water. I use a little teaspoon to add water. I'm a couple days they usually sprout. Then I put them on a south facing window sill. This gives them plenty of light and doesnt dry out the cubes like under a light. When the first set of leaves show, and the white roots start growing out of the bottom of the rockwool cube, you can plant in your medium of choice.
 
Here is what I have seen done with lots of success, IMHO the best way to ensure a good sprout. Germ the seeds in a wet paper towel, put it in a bag and set that in a warm spot (on top of a cable box works well). Seeds need constant warmth or they won't germ. After 12-36 hours the seed should have split and the sprout is sticking out. Carefully pick up seed with tweezers and place it in the wet rockwool with the sprout pointing down. Don't force it in, spread the hole a bit with the tweezers first then place the seed in as gently as possible. You can put a piece of RW on top of the hole if you want, I've seen it done both ways.

Then put the RW in your grow room with temps constant around 80 degrees for proper root growth. After a few days you will see the plant working it's way out. Give it light (not HID lights yet though) and keep it wet. Don't ever let it dry out. After the roots start working their way out of the sides of the RW it is ready for soil or hydro or whatever your setup (plant will already have a few sets of leaves at this point). Usually you don't need to feed at all until it's planted, but keep an eye on it. I know some people give light feedings at this stage. Hit me up if you have any more questions.

:-P Coooooool, thanks guys!

I'm stoked to try out some hempy growing since my last soil attempt got fucked up. Re-used unflushed soil and burnt the shit outta my $10 each seeds. :wall:

Bagseeding this grow, from the dirtiest grossest bud. I'm excited to see how it can turn out if properly treated haha. Maybe throw the guy I got it from some of the finished product so he knows what kinda potential hes got ;-):lol:

Yeah, shit like that happens. Just gotta remember this is trial and error. You will mess up a few times before you get a good system in place. Practicing with bagseed is a good idea but remember genetics on bagseed is usually not so good so your plant will be more succeptable to problems and hermie so pay close attention to light leaks when flowering (ask me how I know). But until you get a few grows under your belt to iron out the kinks, its a good way to go.

Unfortunately I do know what I'm doing for the most part, I was just being an idiot and trying to be cheap...lol. Like the return isn't already about 400x what you put into it. Doh.

Lesson learned :P

I might save some pollen and do some crossing of good females...maybe get my own thing goin' :]
