Best way to use rapid rooters

I had poor germination with my first try of rapid rooters. After a week of no sprouting, I cut them open and each seed had cracked open and a tiny (1 mm) white root was showing. A couple days later they were exactly the same, with no further growth. Not sure if the problem is heat, too much moisture, planting too deep in the rapid rooter, etc.

I had each rooter sitting in a cm of water, in an icecube tray. The tray was in a room that was 76 degrees F. I probably pushed the seed to deep into the rooter; each was about a cm deep, not visible from the top. I watered them each day from the top, so that the rooters were saturated with water. I realize I did something wrong. too wet? At this point I have taken each seed, with the tiny root showing, and put them into soil. but I’m not optimistic given that it has been over a week and there is little sign of activity. Any advice would be appreciated- I have a few more seeds, and I’m trying to decide whether to try the rapid rooters again or go to a different method. I have a growth in another room that started in happy frog potting soil, but I only had 2/5 germinate in that group.

Using rapid rooter for marijuana seeds after germ

Cannabis germination is the process of getting your seeds to sprout, and you know sprouting has occurred when a little white tendril pops out of the seed.

A great method to germinate seeds is to simply take a damp paper towel and insert the seeds, fold the paper towel and put it in a zip lock baggy then keep it in a dark place for 3-5 days until the white tendril is about 1-2 inches long.

Marijuana seeds need the following to get the best germination rates:

Moisture – Keep things moist but not soaking (you can soak hard seeds for up to 24-32 hours, but do not leave seeds soaking in water for longer than that).

Peace – Seeds need to be left alone while you’re waiting for the taproot to show up.

Warmth – Keep things warm to get the best germination rates, but not too hot! Think springtime. Seeds can definitely germinate in cooler temps, but germination tends to take longer when it’s cool.

Gentle – Be careful when checking seeds, and treat them gently when you have to move them. Avoid touching their white root if possible; the taproot is very fragile and easily snaps off!

Plant Root Down – When planting germinated seeds, point the white root downwards into the growing medium to prevent the seedling from having to reorient itself.

Plant Knuckle Deep – When planting germinated seeds, they don’t have to be placed too far under in the growing medium, about a half inch to an inch (1.3 cm – 2.5 cm) down from the surface of the medium should be enough.

Rapid Rooting – HOWTO

Rapid Rooters (Highly Recommended For All Setups)

Rapid Rooters are easy to work with – you just stick your cannabis seed in the Rapid Rooter (pointy side down), keep your seed warm and slightly moist, and let the Rapid Rooter do its magic.

Sprouts emerge and roots appear in just a few days.

Rapid Rooter starter cubes are suitable for all growing methods, including hydroponics, coco coir and soil. They work for every setup and come from General Hydroponics, a trusted company (the same one used by NASA) which is known for the quality and consistency of its products.

I highly recommend using Rapid Rooters over any other starter plugs. They are less prone to problems and work great with any growing medium (including hydroponic systems).

Cons of Rapid Rooters

Can only get 50+ at a time (General Hydroponics currently does not offer fewer plugs per package)

After opening the package, you only have a week or two before they dry out, so if you’re only germinating one or two seeds, you’ll end up having to throw many of the Rapid Rooters away.

There are a few different options for Rapid Rooters, which can be confusing if you’re not sure what you want.

How To Use Rapid Rooters Plugs To Germinate Cannabis Seeds

If you’re looking for the ultimate way to germinate your cannabis seeds then look no further! I traditionally used the paper towel method which I’ve had great success with, but if you’re looking for a 3rd party product to give you the best germination rate possible, then I’d suggest you take a look at Rapid Rooter Plugs by General Hydroponics. They’re extremely easy to use, have a very high germination success rate, and can be used in quite a few different scenarios. In this guide you’ll learn how to use Rapid Rooters plugs to germinate your cannabis seeds before your grow.

How To Use Rapid Rooter Plugs to Germinate Your Seeds:

After you’ve opened the rapid rooters package, you’ll need to soak each of the plugs in distilled water to begin the process. I generally soak them for around 12 hours, but I’ve had success with shorter than that as well. After you’ve soaked your plugs, you can go ahead and place them into your grow tray.

Plant Your Seeds In The Plug:

Now that you’ve gotten the plugs soaked and set up in your growing tray, you can begin to plant your seeds into the hole in the center of your plug. I generally put around 2-3 seeds into each plug. By pairing up seeds, you actually give them a better chance of germination. From here I generally take a pinch of soil off the bottom of the plug and actually cover up the hole where I inserted the seed to ensure a dark environment for germination. This added darkness will help increase your germination ratio.

As seeds begin to germinate and grow, they should be able to push off that added cap and expose themselves to light. If you see any signs of the seeds not being able to find sunlight, then you can help them out and remove the added soil.

Fill Your Grow Tray With Water And Cover:

After you’ve planted your seeds, you can fill your grow tray with about a quarter inch of water and cover the entire tray to help keep a bunch of this moisture inside the tray. I’ve used Saran Wrap in the past with good success. From here, if you have low-intensity lighting, this will improve your germination rate by adding a little additional light as well as heat.

How To Know When Your Seedlings Are Done:

As the seeds germinate and turn into seedlings, you’ll need to know when they’re ready to be transplanted and the real growing can begin. Every day you’ll have to take a peak at the plugs and look for signs of the seeds roots to grow and break through the plug, this will generally mean that it’s ready for a bigger home.

When you begin noticing significant roots growing through, it’s time to transplant to a bigger environment!

Final Thoughts On Rapid Rooter Plugs:

Overall Rapid Rooter Plugs have served me well. I’d definitely start off by looking at our Germination Guide just so you understand the general process of germination, but you really can’t go wrong with these plugs! They make everything extremely easy and they will have a pretty high germination rate, which is definitely a plus since cannabis seeds aren’t cheap.
