starting weed seeds in rockwool

germinate them what ever method you prefer to use,

you dont use a humidity dome for starting seeds and second rockwool cubes will not dry out. they retain allot of water, and with

once split i transfer to cup with holes in bottom covered with a baggie and rubber band for a little greenhouse effect once soil break i remove plastic once again all heating pad .. i normally use heating pad until first transplant at 3 or 4 weeks old

germinate them them move them to the rock wool cubes

another ethod that ive HEARD works is just to put in a shotglass over night, see what happens ins the seed absorbs the moisture until it pops. thats what ya want..

Fill the container/bowl with water from your tap. You may also choose to use water filtered through a britta or reverse osmosis (R/O) water, I’ve had success with all 3 of them so whichever you have on hand will work fine.

To accomplish this, use either Ph down chemicals, or lime juice (as it’s acidic). Add these to the water in small increments (VERY SMALL), and test the water to see where the Ph is. Continue doing this until you have a Ph of 5.5-6.

Important: Do not let the PH of the water go below 5. A Ph this low will damage the fibers of the Rockwool Cube

Now, if you can, place them in a tray with a dome on it. This will help create a little humidity in there which seedlings like. This is not mandatory, but it helps. Whichever you choose, take your cubes and put them in a cool dark place, and leave them alone. The temperature should be roughly 68 degrees F, though my house stays at about 72 and they do fine there. I usually place them above my refrigerator and just leave them for a day or two. My lettuce seedlings sprouted with a quickness the last time I tried, and by the 3rdday they had grown so tall that I had to take the plastic dome off of my container because they were bumping up against the ceiling.

Get a bowl or some other container that is big enough to fill with water and have room left for your Rockwool cubes. Your average salad bowl will work fine for 3 Rockwool cubes, if you are planning on doing more than you will need a larger container.

Most Rockwool cubes come with holes in them, if yours did not, than create a hole in one side that is approximately a quarter inch (0.75 cm) deep.

Before you pop your seeds into the cubes, you’ll need to adjust the cubes’ pH to make them less alkaline. This step also gives you a chance to infuse nutrients into your cubes to give your seedlings the best start to life possible.

Rockwool cubes provide a haven for seeds during germination. By keeping them sufficiently saturated, they provide the three key demands required for successful germination: darkness, moisture, and warmth.

Once you’ve chosen your preferred technique, use the steps below to kick off the vegetative stage:

Seeds (Soil)

Upon mimicking a volcano, the factory machinery then needs to mimic the wind. The lava enters a spinning machine that whips it into thin strands of stone wool. The addition of some binding solution oil helps to hold the strands together. Another machine layers several sheets of wool on top of each other, then a conveyor belt passes them through a series of rollers that compress the wool into a dense mat and improve its structure.

There are many benefits to growing cannabis with Rockwool, especially when doing so hydroponically.

Great for germination

However, healthy soil doesn’t just contain organic substances. Vital minerals and elements required by plants are inert by nature. Some of these are locked away inside of Rockwool and will eventually end up inside your cannabis plants, where they’ll enable and support key physiological functions.
