Rockwool

I soak my rockwool plugs, shake lightly to remove excess water, then move them into a Ziploc container, sealed. Don't add any more water for days or weeks. As long as the lid stays on you keep all the moisture in. Granted, when you air it out some moisture escapes, but its negligible. Not until the seedlings start to poke the bottom of the lid do I take it off. Then leave them in the container under a light and spray once or twice a day to keep them moist until you want to move them to their permanent home. I found bathroom Dixie cups work perfectly for keep the roots together, and easy to rip away when transplanting. Has worked almost 100% for me that way.

 

can you place rock wool cubes straight into soil or is it just for doing dwc?? 

 

pretty certain you can put them in soil. Don't see why not.

 

What system are you using the rockwool in? Many systems you can do without rockwool altogether when starting with seeds. I can't stand rockwool for the same reason you are having trouble.

If you soak the rockwool until its completely saturated and then suck out a ml or so with a pipette or syringe it will be about right but they dry out fast

 

i just got 3 seeds online should i start of germing then rockwool or just put them in the rock wool or just stright in the soil

 

If you're growing in soil yeah just push them straight in there about half inch to an inch deep and lightly dampen the soil

 

without germing? if so thanks.

 

They will germinate perfectly well in the soil, it's the best place for them. keep the soil lightly damp, not wet

 

alright thank you and would a 300 watt led work to grow 3 autos from seed to harvest im sorry for asking it all on this topic 

 

I bought a salad spinner for my rockwool cubes.
 
For the 1" & 4" cubes I use I soak them in warm water to loosen dust & lime once than I ph' them than salad spin them once but I dont spin them dry; Just to make the process quicker and less stressful for the rockwool. Roots form in damp rockwool just dont keep them underwater.
 
I gotta do that right now for my clones that are just now losing water out the dome after 3 days(rIght after this post). 11 Blue cheese clones that all rooted. I root them further in a large 4" cube under drip in black buckets for roots than throw them in Rdwc. Its a lot of work compared to soil. 

 

i sprout my seeds directly in my hydroton. never use rockwool, just personal preference

 

never

 

not all LEDs are the same but if it's a quality unit then probably.

When I germinate seeds I place them in a folded lightly dampened piece of kitchen paper. I put the seed in the crease, and place the whole thing in a zip lock bag and stand it up. The seed germinates and sends a tap root down along the crease. This gives me a long straight seedling.

Once the seedling is about 4" long (stem + root) I place straight in to clay balls and have the level of the water submerging the tap root. It's then treated as normal and growth is very fast compared to mucking about with rockwool at the start

 

Here's a photo of one of my seedlings right before I place in the clay balls ...
