Micro Growing: Growing a Small Weed Plant

Cannabis varieties Growing

Every expert cannabis grower started somewhere, and if you’re just setting out on your journey towards reaping the rewards of a bumper crop of sweet, sweet bud, cultivating a small but perfectly formed weed plant is an excellent first step.

In fact, even more experienced weed producers love to get in on the Micro Growing action, as it gives them a chance to try out new varieties. Cleverly, some growers even use their home Micro Growing setups as a valuable source of strains to use in crossbreeding experiments.

Growing a small weed plant: Advantages and disadvantages 

It really is a no-brainer. So with that in mind, here is our guide to the ins and outs of Micro Weed Growing.


In addition to the sense of achievement you’ll enjoy once you’ve established a flourishing weed plant in your home, some many benefits of Micro Growing include:

  • Does not require much space.
  • Hones your weed growing skills.
  • Looks great in your home.
  • Cheaper and more rewarding than buying commercial weed.


Aside from the obvious limitations in the size department, the main drawbacks of growing a small weed plant in your home are:

  • Your plant will require regular attention.
  • Smaller yields than full sized plants.
  • Might test the patience of novice growers waiting for their first harvest.
  • Additional equipment required to maximize yield/THC content.

How to Grow a Small Weed Plant

If you already grow your own weed, you’ll know that these incredible plants require a great deal of care and attention in order to enable them to reach their full potential. However, for the benefit of newcomers and as a recap for everyone else, the basics you’ll need are:

  • A nutrient-rich growing environment.
  • Lighting which mimics the natural daylight cycle.
  • Enough warmth to simulate the type of climate in which cannabis plants thrive.
  • A regular and balanced watering and feeding schedule.

For the purposes of this article, we’ll assume that you will only have access to basic hydroponics and UV lights. Fortunately, this does not mean that your small weed plant won’t be able to produce a highly enjoyable crop. It just might not be quite as potent as the stuff you’re used to finding at your favorite local dispensary or coffee shop.

In order to emulate the techniques used in a commercial weed growing setting in a domestic context without expensive equipment, simply follow the steps below:

  1. Pot your plant in a specialist weed going compost.
  2. Remember to feed and water your plant regularly and incorporate this into your daily routine.
  3. If you do not have a UV light, choose the location of your plant in your home carefully so that it gets plenty of natural light.
  4. If you have got access to a basic UV light, maximize its effectiveness by keeping your plant in a container such as an old fish tank or a large storage box lined with reflective material (e.g. tinfoil or white paper).
  5. Place your plant close to a heat source such as a radiator, or even in your kitchen near the oven.

Other than that, all you need to do is make sure that you prune your plant carefully in order to keep it within your size requirements. While doing this, remember to take care not to limit your final yield, and use your judgement to ensure that you harvest your bud at the correct time.

Top 3 Best Strains for Micro Growing

We’re assuming that you won’t have access to the sophisticated lighting equipment necessary to trigger the flowering phase as required by regular or ‘photoperiod’ varieties. As such, for reasons of practicality and convenience we recommend that you stick with autoflowering cannabis seeds.

Furthermore, we suggest choosing a strong strain to offset some loss of potency which is an inevitable consequence of growing a weed without the aid of professional standard equipment, not to mention the fact that you may only be growing one plant. The good news is that there is a whole host of superb weed strains on the market today which will fulfill these criteria handsomely.

While which particular strain is right for you will largely depend on your own preferences, a few of our favorites include:

1. Northern Lights Autoflower

Needing no introduction, Northern Lights has been delighting weed lovers the world over since the early 80s when it was first created in Seattle, Washington. The strain was then further refined by expert weed breeders in the Netherlands. In the decades since it has triumphed in pretty much every major contest the Cannabis community has to offer, including the coveted first prize at the High Times Cannabis Cup.

It was inevitable that this iconic weed strain would be at top of the list when weed breeders were developing new varieties which could be grown with relative ease, and sure enough the Autoflower version does not disappoint. Blessed with the same attributes which made Northern Lights famous in the first place, this mellow yet euphoric bud is a pleasure to smoke. With a sweet flavor and fragrant aroma, it makes a solid choice for any Micro Growing project.

2. Critical Autoflower

Developed relatively recently, Critical is beginning to become a firm favorite among weed lovers who appreciate something a little different but don’t want to compromise on the quality of their smoke. Being derived from a surprisingly robust plant, the Autoflower version shares the original strain’s mellow yet highly enjoyable effects, not to mention its distinctive sweet fragrance.

In common with all Autoflower weed varieties, this version does not require precise lighting techniques to trigger the flowering phase. Indoor yields are highly respectable at up to 450 grams per m2, and that all-important THC content can reach the dizzy heights of 20%, making Critical Autoflower a compelling option for weed lovers with refined tastes.

3. Girl Scout Cookies Autoflower

An Indica-dominant variety which was created by crossing the US favorite Girl Scout Cookies with a Ruderalis strain, Girl Scout Cookies Auto boasts an impressive THC content of 22%. Additionally, the finely balanced blend of genetics present in this highly advanced strain means that it also succeeds in replicating most of the generous yields offered by the original variety.

This equates to yields of around 250 to 400 grams per m2 when grown indoors, making it a superb choice for use as a Micro Growing plant. Expect to be ready to harvest your crop in a little over 12 weeks. Once you’ve had a chance to dry out your autoflower buds, you’ll be able to enjoy the delicious chocolate and caramel flavor notes that give this characterful weed variety its name.
