Taking Care of Your Plants While Vegging

For today’s piece about vegging cannabis, we will assume that you have planted your seeds or cuttings already. After the process of propagation, small and fresh baby plants have now started to grow. You might have used a special growth medium or a plastic dome to grow them initially. Now you have brand new marijuana plants to take care of. It is time to find their spot in your grow room and start improving their health, strength, and shape.

Growing indoor gives you the opportunity to build just the right conditions for your plants. The growth phase is the heart and soul of your plant’s health - just follow our ideas and tips from this article. We have covered light, air, and water in a hydroponic system before and I recommend you to check out these resources for best practices for your cannabis plant


The vegging stage starts once the plants have developed enough of a root system to take in water without a humidity dome that was used for seeds or cuttings before. Give your plants 5 to 10 days of transition. Slowly start increasing lighting and air flow.

Pro Tip 1

In the vegetative stage, you will want about 18 hours of light for your plants. Use full spectrum lights. More Light = Faster Growth. Keep the humidity at 45% to 65% with temperatures between 72 and 85 degrees. Keep fresh air moving within your room using your exhaust and oscillating fans . You will want to use a nutrient solution with high nitrogen and potassium and medium to high phosphorus.

Give your plants some time for a strong vegetative phase. Grow it up to 18’’ inches tall, with at least 3 to 6 leaf branches, before switching to flowering phase.

Keep in mind how big you need your plants to grow. When using the same space, having a lot of plants will mean less time until the room is filled in buds. A smaller number of plants means the need for them to grow bigger and taller until the space is completely filled.

Different cannabis strains lead to very different shapes and sizes of plants. The balance between filling your space as much as possible and giving your plants as much room as possible might take some experimentation and learnings on your side. While a Sativa might grow another 150% after transitioning to the flowering stage, Indica will only grow about 25% more.

Your plants will grow a lot more if they are missing light - they will stretch as much as possible and get very tall while they try to reach the sun. There will be many blank spaces between the nodes and branches which will negatively affect your yield. A stronger ventilation might keep them smaller and bushier.

In the vegetative stage, you are setting the standards for your cannabis plant and your yield.

How to Take Care of Your Cannabis Plant

First things first: if your plant is in good condition, the factor that will limit or support your plant’s growth the most will be light. Don’t let them search for light while sitting in a dark spot. Also, don’t let your plants get burnt by the lamps if they're too tall.

The goal of vegging canabis is to grow a strong and healthy plant. We will want the buds to be exposed to the light because this will get them to grow much more once transitioning to the flowering phase.

These are the tricks that will let you grow a perfect plant for your commercial production:

  • size of pots and net pots
  • cutting your plant
  • removing leaves
  • supercropping


The size of your plants will be determined by their roots. The amount of roots will be determined by the pots or net pots you are using. Give the roots room to grow and the plant will grow as well. If you are only using your plant for a few months, a small pot will be okay. Some hobby growers keep their plants for years. As a result, they will need a much bigger pot. In soil, you will have to water your plants a lot when growing in a small container. In a deep water system, this won't be a concern.


Cut the stem right above it’s second set of leaves from the top. Now your plant will focus on two colas and grow a strong Y-shape. Give your plant some time to rest after the topping because the procedure will slow down growth. But after a few weeks you could do the same process again.

FIM-ing (Pinching)

This technique is called FIM for "F*ck I Missed" it because it is based on the cutting of topping. Only instead of cutting the stem right above the leaves, you pinch off the newest leaves or cut off the newest tips. This way, the plant will grow four new coals. There will be a lot less slowing down of the growth process with pinching.

Removing Leaves (Defoliation)

Removing leaves in the vegetative phase will slow down the growth process of your plant. Only remove leaves from a healthy plant. It will let you control the shape and growth speed of your plant. Use this technique to create a smaller plant that exposes its buds to the grow lights.

Super Cropping (Bending / Low Stress Training)

These steps create a lot less stress for your marijuana plants because they are only tied down or bended. There is no cutting involved. Through bending, you can make your plant grow a horizontal rows of buds. Bend over branches that are taller than the rest. You can try tying them down or use weights. Super cropping is essentially a technique where you bend your plant until the bent point is slightly damaged.

Vegging Cannabis: Growing the Perfect Shape

In this phase, you are looking to grow your small and new brands into healthy and big plants. For commercial production, it is best to grow your plants into a horizontal sea of buds that than can be beautifully exposed to light in the flowering stage and will create the best yield for you. Vegging cannabis is really a preparation for flowering stage. It sets the standards for your yield because now you are going to make the changes and tweaks that will later accelerate your yield in the flowering stage.
