mixing strains

Or you could just put all the seeds in Rapid Rooters now, and hope for the best as far as the slow-sprouting ones. Letting the unsprouted seeds stay in the paper towels longer improves the germination rate in my experience, but it’s simpler (easier) to move them all at once. Alternatively, you could place your sprouted seeds directly in the final growing medium (coco or soil).

I think these help them get started, but I’ve grown many successful plants by just putting the germinated seed directly in its final home. Gently place the germinated seed inside, root down. Place the seed close to the surface so it doesn’t have far to go. If you have a root that is curved or bent, don’t try to straighten it out. Open the Rapid Rooter and lay the germinated seed down gently. When you slowly close the Rapid Rooter, the bent parts of the root will end up in the “crack” of the Rapid Rooter that you cut to split it open from the side. Most seedling plugs will go back into place easily, and you’ll barely be able to tell it’s been opened.

I love Rapid Rooters because the texture of them causes the seeds to stay in place and not “fall down” further into the hole once you’ve got the Rapid Rooter closed. While that’s happening, set up your soil, coco or hydroponic tub if you haven’t already. It will still be a few days until your seedlings arrive, but you want to make sure to have everything ready before the seedlings need to be planted. If in soil or coco, water your container right after putting your sprouted seed in the Rapid Rooter. This will give it some time to dry out before you install your seedling, so your new roots will have the perfect wet-but-not-too-wet environment in a few days! Remember, seedling roots love a good mix of air and water. You won’t be watering this thoroughly again for a while to avoid overwatering a young seedling, so by watering thoroughly now, you know there will be some amount of water throughout the whole growing medium. 5.) Water the seedling in the Rapid Rooter until you see a root out bottom, 1-2 days. Make sure to always keep the Rapid Rooter moist but not soaking wet and give plain, pH’ed water. Since your seed has already sprouted and been in placed into the right growing position, it’ll often pop its head out within just 12-24 hours! Sometimes you see just the leaves, but often you actually see the seedling push the shell above ground. Like a butterfly coming out of a cocoon, the seedlings gain strength during the process of pushing off the shell. If you manually remove the shell for the seedling too early, you may feel like you’re helping, but sometimes the leaves have trouble opening afterwards. This is because there’s a “film” that can get stuck on the leaves, which would typically come off with the shell but may get stuck to the leaves if the shell comes off early. Plant leaves still usually “break free” from the film eventually but it just goes to show that sometimes the best thing you can do for your seedlings is have patience and leave them alone. Shells usually falls off naturally as the seedling grows. That being said, if you have a seedling that’s stuck in a shell for multiple days, sometimes you may need to go in and help. But try to let the seedlings break free from the shells themselves, if possible. Don’t use a dome on seedlings unless it’s very dry where you live. If you do use a dome, consider keeping a vent open and watching the humidity. A young seedling doesn’t require as high humidity as clones (which are what the domes are designed for), and seedlings tend to get “wet feet” and stop growing as fast in constantly wet conditions. Water your seeding in the Rapid Rooters until you see a root coming out the bottom. During this time, give seedlings bright, but not too bright light. A fluorescent (CFL) bulb kept several inches away works well! I’ve left mine on the kitchen table next to a sunny window, and that’s also worked fine for me as long as it doesn’t get too hot. You should see a root come out the bottom in just a day or two!

After you see your first root, it’s time to… 6.) Put Seedling in its New Container! Dig a hole half the size of the Rapid Rooter, and place your seedling directly inside. You can bury the Rapid Rooter all the way, but having it stick up into the air gives the seedling roots a little extra oxygen while they’re small.

Example of cannabis seedlings growing in coco coir, about to get seedling-strength nutrient water! If these seedlings were in soil, I would be giving just plain, pH’ed water for the first few weeks. Give 1 cup in a bigger than 3-gallon container, especially if it still feels wet from when you watered before. Give 2 cups water in a smaller container or drier medium. The reason you would give more in a smaller container (which seems sort of a paradox) is because the moist medium will dry much faster in a smaller container, while a big container will hold onto the water for longer.
