How And When To Transplant Cannabis Seedlings
The seedling phase is essential in the life cycle of cannabis. The cultivation process starts with seedlings, and transplanting plays a crucial role. A mistake in this stage could lead to losing the crop. This guide will assist you in transplanting seedlings correctly and growing outstanding cannabis.
The Importance of Caring for Cannabis Seedlings
After germination or cutting, your cannabis seed or sprout requires a place to root. During the seedling stage, the main objective is to develop a healthy root zone. If seedlings struggle, they might never fully recover, and they may not reach their full potential. In the worst-case scenario, the seedlings could die off, ending the grow prematurely.
The Optimal Conditions for Seedlings
Cannabis seedlings demand delicate care. Transplanting cannabis seedlings like babies, and support them if needed with soft gardening tools.
An 18-6 light schedule is ideal, and white light from sources like CFL, MH, or LED is preferred. If you have a sunny windowsill, that can work as well. They should however be moved under a more powerful light if they are starting to stretch.
High humidity (around 70% RH) and temperatures in the 20–24°C range create a perfect habitat for seedlings. Tools like a propagator, thermo-hygrometer, and spray bottle of water can help maintain these conditions.
Stretchy or floppy seedlings may indicate that the grow lamp is too far from the canopy. A cool white 250W CFL can be placed 15cm above seedlings without damaging them.
What’s the Best Starter Substrate?
Keep the medium wet but not waterlogged. An effective wet-dry cycle is essential. Resist overwatering, and mist plants if unsure. Touch the medium to gauge its dryness and maintain high RH.
Starting in one medium and switching to another can be risky. It’s best to keep it consistent. Avoid starting seedlings in soil and then transplanting them into a DWC bucket.
Cubes, Cups, and Small Containers
Choose the right container based on your growing style. Rockwool cubes are suitable for hydroponic growers, but not for soil growers. Oxygen-rich mediums that drain well are ideal for soil and/or coco growers. Many growers use cups or small plastic pots, and improvisation with proper drainage can work too.
When to Transplant Seedlings
Transplant your seedlings just before they outgrow their current container. Don’t delay, as rootbound plants may take time to recover or be permanently stunted. Typically, 7–10 days are enough for seedlings to outgrow small starter pots. Waiting too long is slow the growth of your cannabis plants.
How to Transplant Seedlings
Transplanting methods vary based on the container type. Dry soil is best for transplanting. Turn the plant upside down, and gently slide it into the larger container. Replace any lost topsoil, and add a little water. This method ensures stress-free transplanting. However after transplanting it is a good idea to water your plants to get things in the new pots mixed up well and to help get the new roots going in the new soil.
Potting Up vs Beginning with Big Pots
You can sow cannabis seeds directly into a large container if it’s up to 11l, but this can limit the potential of your plants. Transplanting is essential for optimal growth and shouldn’t be avoided, even by beginners.
Mastering the art of transplanting seedlings is crucial if you aim to grow robust marijuana plants. Follow these guidelines, and you will be on your way to growing great ganja.
How to Successfully Avoid Transplant Shock in Your Cannabis Plants
Understanding when to transplant cannabis plants can often feel like a guessing game. However, there are clear signals that your plants might need more room for root expansion. Here’s how you can identify a rootbound cannabis plant:
Soil Dries Out Rapidly
If you notice that your potting medium is drying out just a day or two post-watering, it’s a red flag. Rapid drying indicates that your plant is consuming water at a pace that the current container can’t sustain.
Unexplained Root Issues
When a cannabis plant is confined to a small container or becomes rootbound, it starts showing issues at the root level. Signs like droopiness, unexpected leaf symptoms, or nutrient deficiencies such as spotting or yellow leaves emerge. If all other factors are stable and you’re still facing these problems, it’s high time to consider a transplant.
Significant Growth or Extended Time in Same Pot
If you’re maintaining a mother plant for an extended period or if your cannabis plant has doubled in size while in the same pot, these are strong indicators that a transplant is needed to prevent becoming rootbound.
Plant Stability Concerns
A top-heavy cannabis plant that looms much wider and taller than its container is prone to tipping over. Transplanting into a larger pot offers the stability the plant desperately needs.
Sometimes, it’s visually apparent that a plant has outgrown its container. Photos showcasing oversized plants serve as clear examples of those in urgent need of a transplant.
By staying vigilant for these symptoms, you can proactively manage your cannabis plant’s root health, avoiding the restrictive and growth-stunting condition known as being rootbound.
Identify the Optimal Time for Transplanting
To set your plants up for a smooth transition, you need to determine the best time for the transplant. Aim to move your cannabis plants when their roots have sufficiently filled the container—enough to hold the soil together but before they start wrapping around the edges. Transplanting at this stage prevents the plants from becoming rootbound, which can hinder their growth.
Pre-Transplant Watering is Essential
A day or two before the transplant, water your plants. Moist soil sticks together well, aiding in an easier, less disruptive move. The key is to keep the soil moist but not drenched to facilitate a smooth slide out of the current container.
The Risk of Transferring Too Late
It’s a rule of thumb in cannabis cultivation: it’s far better to transplant a little too early than too late. Overgrown roots may complicate the transplant process and increase the likelihood of shock.
Timing Before the Flowering Stage
Ensure your cannabis plants are in their final pot at least a week or two before transitioning them to the flowering stage. Transplanting during the flowering or budding stage is ill-advised as the stress can compromise your yield.
Employ Sea-Kelp Extract for Quick Recovery
If your plants show symptoms of transplant shock—like leaf drooping or slowed growth—a sea-kelp extract can be your saving grace. This natural remedy is often available as a liquid fertilizer and can expedite your plants’ recovery.
Consider Direct Planting for the Risk-Averse
If the idea of transplanting makes you anxious, there’s an alternative: plant your seeds or clones directly into the final container. This method avoids transplant stress entirely, although you must exercise caution to prevent overwatering in the early stages. Adding perlite can enhance soil aeration and water drainage.
Seamless Cannabis Plant Transplanting
Transplanting is a critical step in your cannabis cultivation journey, and doing it correctly can spell the difference between a thriving garden and one rife with problems. Here are refined tips to guarantee a smooth, stress-free transplant.
Hydrate Before the Big Move
Quench your plants’ thirst 24 to 48 hours before transplanting. This ensures the soil is moist enough to hold together, yet not too wet, enabling an effortless slide out of the container.
Prepare Your New Home Base
Before initiating the transplant, pre-fill your new pot with potting soil, stopping two inches from the rim. This extra space aids in efficient watering later on, preventing runoff.
Pre-Moisten Your Destination Soil
It’s essential to hydrate the soil in the new pot prior to transplanting. Dry soil can be poor at absorbing water, making it difficult for the new roots to acclimate.
Create a Welcoming Hole
With the new soil prepared, carve out a hole in the center approximately the size of the plant’s current container. This hole will be your plant’s new home.
Loosen the Rootball with Care
To safely free your plant, use a butter knife to slide along the container edges. This action gently detaches the rootball. When lifting the plant, avoid holding it by the stem. Instead, employ a flat hand to grasp the top and invert the pot, allowing the rootball to fall gently into your waiting hand.
Nestle Your Plant in its New Home
Place the rootball into the hole you’ve previously prepared. If the soil level appears uneven, add more soil to create a flat surface.
Immediate Watering is Key
After situating your plant, press down the soil gently around the roots to establish good soil contact. Follow this up by watering the plant right away to solidify its new position.
By implementing these meticulously curated tips, you can accomplish a stress-free transplant, setting your cannabis plants on the path to robust growth and high yields.
