A Guide to Transitioning Clones Outdoors

Know the Law in Your Area

As the laws around industrial CBD hemp change, your first step is to take the time to fully understand the legal aspects of growing, storing, transporting, selling, or consuming CBD products in your area.

Starting Indoors, Growing Outdoors

Although starting your cannabis clones indoors and then moving them outdoors takes a little planning and some extra work, many growers think it is well worth it.

They suggest that cultivating outdoor hemp plants can result in:

  • taller plants with a higher yield
  • a product that has a unique flavor and scent
  • a lower cost of production

To ensure that your plants make a healthy transition from indoors to outdoors, there are a number of best practices to follow.

Growing Season

As you plan your outdoor growing season, there is key information you must take into account, including:

  • When you will have daily temperatures that will not dip below 55 degrees F for sustained periods of time: You don’t want to transition your plants outside early and expose them to too much time below 55 degrees that could stunt their growth or even kill them.
  • How many hours of daylight per day you will typically have during your growing season: This is important information to help you plan the cycle of light exposure while you are starting your clones indoors.

Indoor / Outdoor Photoperiods

Many indoor growers give their cannabis plants an 18 hour photoperiod every day (18/6 cycle). However, growers starting plants indoors then moving outdoors often use a cycle with a shorter period of daylight.

This shorter period is matched to the natural light exposure the hemp clones will get once they are moved outdoors.

For example, if your growing season starts with 14 hours of light per day, give your cannabis plants 14 hours of light a day when they are indoors.


The ideal soil for outdoor cannabis plants is:

  • Well-drained
  • Rich with organic matter
  • Slightly acidic

A month or more before they plant, many growers dig large holes for their plants and mix in compost and other organic matter.

Proper pH

You want a pH in the 5.8 to 6.3 range (ideally 6.3) for:

  • The growing medium used to start your clones indoors
  • The soil that you will be using for your cannabis plants outdoors
  • The water you are using to hydrate your plants


Although you don’t want to overfeed your plants, to be healthy, they need nutrients such as:

  • Calcium
  • Iron
  • Magnesium
  • Nitrogen
  • Phosphorus
  • Potassium
  • Sulphur
  • Zinc

A good cannabis plant fertilizer is typically sufficient, but you might need to strategically supplement to avoid nutrient deficiencies that can lower your yield. Learn more about: Diagnosing & Treating Cannabis Plant Deficiencies

Hardening Off

Plants moving from indoors to outdoors need to be hardened off — a process of gradually introducing plants to sunshine and cool nights by moving them outdoors for a portion of the day, for a number of days, before transplanting.

  • Because natural sunlight contains a broader spectrum of light than most indoor grow-lights, start your plants in partial sun to limit the amount of full sun they get before they are hardened.
  • Start them in shade or partial shade for a few days and then, over time, progressively move them to get more direct sun.
  • Start leaving the plants outdoors for a limited time, progressively leaving them outside for a longer period of time each day until they are acclimatized and ready to be outdoors full time.
  • Make sure your plants are properly hydrated.
  • Inspect for diseases and pests. The leaves are more vulnerable before they harden off.
  • Monitor the container when the plants are hardening off, direct sunlight can overheat the container and soil — and thus “cook” the roots.
  • Start your plants with an hour or two outside the first day. The next day bring them out for an hour or two more than the first day. Keep doing this until the leaves toughen up (about 10 days).
