We’re going to show you how to properly transplant your young cannabis plants, with some valuable tips that’ll make this process a success.
When do you transplant a cannabis plant and what kind of pot should you use?
Your first real transplant will take place one week to 10 days after planting. This is when you’re faced with a decision, are you moving your seedlings to their final home or an intermediate pot?
An intermediate pot gives you more chances to perfect cycling your plants wet to dry with your feeding and watering. You become used to how much your plants drink, and how much a dry versus a thirsty pot weighs. We highly recommend this route for beginners.
Transplanting from seedling straight to the final pot is recommended once you have some experience, or if the pot you’re finishing up in is pretty small (in the one to three gallon range).
Tip: Plant into a dry medium and water after. It reduces potential waste and dry soil is much easier to clean up – any leftover dry soil can go straight back to the bag.
Preparation is key
When preparing your pots, never pack your soil. You want the first watering to be able to move around and fully saturate rather than find a path of least resistance. When planting, the aim is to seat a new plant without spaces or gaps in the medium. Successive waterings compact the soil naturally. This will make watering easier and produce a better root structure.
Make sure to leave room for watering. Never fill soil up to the rim, or you’ll find yourself pouring a little, then waiting or constantly spilling nutrient solution onto the floor.
What about moving cannabis seedlings straight to their final home?
If you are moving seedlings to their final home, I have a good tip to make sure they shoot roots everywhere, rather than stunt out. For the first few waterings, including the initial watering, saturate the media to only 50%, concentrating on a column down the center. Slowly water all around the seedling, keeping about half the distance from the rim to the plant. Plants will immediately shoot roots down as far as they can.
Tip: Never let the media dry completely. The first few times you remoisten, apply only 50%. Once you see roots protruding from the bottom, you can start the wet to dry cycling as detailed in the feeding and watering video.
How do you feed your cannabis after transplanting?
Your soil must now be charged with food, either by using a nutrified soil or adding nutrients regularly. Stick to your feeding plan. If you transplanted to a nutrified soil, you might not need additional nutes for a few weeks. The use of super soil, on the other hand, means you won’t need to supplement at all.
Follow the feeding plan you chose and you should be okay, but always observe your plants. At this stage, purple stems and yellow leaves commonly indicate lack of nutrients or the inability of the plants to uptake nutrients because the pH is off.
A few weeks after the initial transplant is when you want to increase the nutes. This is when you can push them and get them to produce what large-scale commercial agriculture calls greenhouse tip. The slight tip burn lets you know that the plant is full of nitrogen, and you’ve reached the maximum level.
When and how do I move my cannabis plant from an intermediate to a final pot?
Typically, it should be within two to three weeks, but this also depends on the light source, strain and overall health of the plants. Physically, they would have already doubled or tripled in size and have developed substantial roots and foliage at this stage.
Make sure the root ball is relatively dry before transplant. A wet root ball would fall apart under its own weight. If you are transplanting into a pot three or four times the size of your intermediate pot, the first watering should follow the same half-saturation pattern we spoke of earlier – a nice central column of water for the first couple of waterings and then cycle wet to dry. This will give you an amazing root structure and a strong, vigorous plant.
Is there anything I should avoid after transplanting?
Avoid flipping your plant for at least a week after transplant. Let your plant move into all the fresh soil and settle in its new home. It will thank you for it later on.
