root riot seed germination

germinating seeds in root riot cubes

Hey guys, since my roommate fucked up my last few seeds from my first seed order, I want to make sure that my newest pretties have their best chance at survival.

I have root riot cubes that I use for clones, so I figured I would just use those since they work so well for cuttings. What I’ve done, is put the seeds in the cubes, and then I put the cubes into an ice tray with holes drilled in the bottom. I then set the tray in a 1 gallon bucket, and poured a mix of 1 part h2o2 and 5 parts h2o, so that the cubes can soak it up. Then I just put it under the light:

The main thing I’m wondering, is what to do with the light. Its on a 16/8 veg photoperiod under the t5’s. Should I cover the bucket with a towel? Or will they be fine under the light?

Lemme know if I’m doing anything wrong here. I’m running blue dream (hso) cotton candy (delicious seeds) purple wreck (reservation privada) and desert diesel (hso)

Thanks for the replies guys. I use the peroxide BC it dissolves into water and oxygen, which is good for the roots. I read several places to do it with clones so I figured it would probably work for a seed as well.

I was wondering about covering it, my light just went off but I’ll cover it up before it turns back on. I’m really looking forward to these strains.

I’d like to see you working with a heat mat and humidity dome. I went from stuggling with the germing process to germing like a pro.

Those cubes are going to dry out without a dome and even with that t5 light you have it’s going to be tough to get the root zones to the proper temps without a heat mat unless it’s very warm where you live.

Heat mats and humidity domes are worth every penny. You can get both for about the cost of 2 seeds and you’ll avoid major headaches since germing can be a bitch without them IMO.

^^^ there ya go. only thing I’d advise is I’m not too keen on leaving seedlings in high humidity (this is from years of experience). they are less prone to wilting, damping off and whatever else if you give them fresh air as soon as practical. so yeah dome them until they pop, but be prepared to moisten the Rapid rooters 2x a day (IME if you wet them to the point they stay moist for longer than 24hrs then they are too wet, but that’s not a absolute, RH being about 50%), basically be prepared to check and moisten your seeds at least once in the a.m and once in the evening

I’ve also been placing a 23W “:daylight” CFL about 1″ from the seedling (using one of those clip on worklights w/reflector) . some advise against too much light bui the last 5-6 seeds I’ve popped have responded well: nice strong short and dark green. I see a LOT of seedling pics here and IMO they are too stretchy/spindly

How to Germinate Cannabis Seeds

Aug 23, 2018 · 3 min read

Cannabis, like all life, is fragile at inception. Sow cannabis seeds ¼–½” deep, pointy-end up, in a starter cube or well-aerated soil. Seeds germinate best at room temperature, with moderate humidity and a 1:1 ratio of air to water in the grow medium. Optimize environmental conditions to ensure robust germination and vigorous growth. Stable conditions and attentiveness are key to nurturing young plants.

Seedlings will emerge after a few day s and reach toward light. The seed casing opens like a clamshell hinged at the pointy tip. This reveals a tender white radicle — a small root tip that plunges downward while the seed casing is thrust up toward the light. Emergent seedlings unfurl to greet the sun and push away the seed casing. All of this happens in the course of a week using stored energy from inside the seed.

Don’t stress — sprouting marijuana seeds is easy! Take your time, smoke a joint, grab a beer and turn on your sound system. We recommend the Workingman’s Dead for this garden project. And remember — no root, no fruit!

Creating a Fertile Environment

Root Riot or Rapid Rooter cubes are a favorite for germination because they make it easy to keep the grow medium irrigated for success. Germinating seeds are very sensitive to excessively wet or dry conditions. Tender young plants will wither in arid conditions or become moldy in a swampy environment. Keep germinating seeds out of direct light until they have emerged from the grow medium.

Seeds germinate best in cozy conditions. The ideal germination space is consistently 72°-75°F, 45% humidity, away from direct light and excessive drafts. The top of the fridge in the kitchen is often a good enough spot. Just don’t forget about them!

Soak Cubes Before Use

Cubes should be soaked in a bucket of water for a few hours before use to ensure that they are evenly hydrated. If a pH meter is available, adjust all water to 6.0 with a horticultural grade acid or base.

Organize Cubes In A Starter Tray

Place cubes in a propagation tray such as the Mondi Mini-Greenhouse Propagation Dome; however, don’t use the humidity dome. It is meant for cloning and it will cause mold and moisture stress if used for seedlings. Make sure to label each seed in the tray!

Insert Seeds Into Cube

Plant seeds in the prefabricated hole in the cube, or flip it upside down and make your own hole. Insert the rounded end of the seed downward and insert to a depth of ¼–½”, approximately to where you can no longer see the seed. A pair of tweezers is useful for this step.

Water Cubes Daily

Water cubes once a day with plain water, or more often if the germination room is dry or drafty. Check on the cubes several times a day and be mindful of cube color. Wet cubes are dark brown; dry cubes are light tan. Do not fertilize yet.

Seedlings will usually emerge from the cube in 24–72 hours, sometimes longer. At that point, they should be transplanted and placed 12” under cool spectrum fluorescent lighting. Germinated seeds usually shed their seed casing as they first emerge from the cube; however, sometimes the seed casing will get stuck and appear to trap and prevent the emergence of the first set of leaves. The seedling will almost always shed the seed casing eventually, even if it takes a week. Attempting to remove the casing manually may physically damage the tender seedling.
