Cannabis Clones, Seedlings, Seeds. Which Is Best?
Contents
For as long as people have cultivated cannabis, one debate has never gone away: Is it better to grow from seed or use cannabis clones? In recent years, a third option has become more common in both hobby and commercial grows, buying established seedlings.
If you were hoping for a quick and simple answer, then sorry to disappoint you! The truth is, there isn’t one best method. In this article, we’ll take a closer look at the pros and cons of each of these three starting points.
Growing from Cannabis Seeds
Growing from seed is the traditional method and remains extremely popular, especially with home growers and breeders. Discover our seed catalog.
Pros of Growing from Seed:
1. Strong Root Development
Seed-grown plants develop a natural taproot, which anchors the plant and supports stronger root systems overall. Clones do not produce a true taproot. Having a taproot contributes to the health of a developing plant in terms of:
- Encouraging more effective nutrient uptake.
- Proving greater drought resistance.
- Increased long-term vigor of the plant.
2. Clean Genetic Start
Starting from seed reduces the risk of importing hidden problems into your grow space. When seeds come from a reputable breeder, they are generally free from pests, viruses, and systemic diseases. This is increasingly important as pathogens such as hop latent viroid (HLVd) have become widespread in clone markets.
3. Genetic Stability & Transparency
With feminized or autoflowering seeds from an established breeder, you’re starting with stable, defined genetics rather than relying on the history of a mother plant you may know little about. The breeder (seed company) will provide accurate information about the strain in relation to expected flowering time, typical growth structure, flavors/terpenes and cannabinoid profile.
4. Ideal for Pheno Hunting & Breeding
Seeds offer genetic variation. This is essential if you want to:
- Select standout phenotypes.
- Breed new cultivars and experiment with genetic traits.
Cons of Growing from Seed
- Slightly longer grow time (extra 1–2 weeks in early stages).
- Some variability between plants (unless working with highly stabilised lines).
- Requires germination skill and early-stage care to take the plant from germination to seedling stage and beyond.
Growing Cannabis from Seedlings
Seedlings are young plants that have already germinated and established early roots. They sit between seeds and clones in terms of maturity. They are certainly a convenience option – especially in countries where clones and seedlings are legally sold. Discover our seedlings catalog (available to customers in Austria and Germany)
Pros of Buying Seedlings
1. Saves Time
Growing from seedlings is inevitably quicker than growing from seeds. You skip the germination phase and fragile early stage where the plant is establishing its taproot and jump straight into the seedling stage.
2. Early Uniformity
Seedlings come already sprouted and established and may already show healthy structure and vigor, however this is dependent on the source. Getting seedlings from a reputable supplier (ideally one which offers seedlings grown in lab-style conditions) is key.
3. Beginner Friendly and Less Risk
Ideal for new growers who feel nervous about the germination success, seedlings remove much of the early-stage risk.
Cons of Seedlings
- They need gentle care while getting established and are still vulnerable to transplant shock when re-potting.
- Possible introduction of pests if sourced from an unreliable supplier.
- Less genetic control than seeds unless sourced directly from a breeder.
Growing from Cannabis Clones
Clones are cuttings taken from a “mother plant,” meaning they are genetically identical to the original plant. Commercial growers frequently prefer clones because they deliver consistency. Discover our clone catalog (available for customers in Germany and Austria).
Pros of Growing from Clones
1. Guaranteed Genetic Identity
A clone is an exact copy of the mother plant. If the mother is proven, you know exactly what you’re getting with a clone in terms of:
- Same cannabinoid profile
- Same flowering time
- Same growth structure
2. Faster Start
Clones are already biologically mature so they are ready to put into the veg stage immediately and reach harvest slightly faster than seed-grown plants
3. Uniform Canopy Management
For growers running multiple plants the predictability and uniformity of clones is a big advantage. Growers will have consistency in height and flowering times and yields, making crops grown from clones more efficient and easy to manage.
Cons of Growing from Clones
1. Disease & Pathogen Risk
Planting infected clone stock is an aspect of clones which has caused big headaches for some commercial growers growing at scale. Clones infected with pests or diseases – often not visible – at the time of purchase can lead to serious losses down the line.
Clones can carry fungal spores, root aphids, spider mites and Hop latent viroid (HLVd). The best way of avoiding inflected clone stock is to buy from a reputable source (i.e. clones grown in lab conditions by reputable suppliers).
2. No Taproot
Clones develop fibrous roots but lack a natural taproot, which may slightly reduce root robustness compared to seed-grown plants.
3. Genetic Drift & Mother Plant Fatigue
If a mother plant is kept too long, genetic expression can degrade, plants can become less vigorous and mutations can occur. Clones are only as good as the mother they come from.
So Which Is Best?
The answer depends on your goals.
| If You Want… | Best Option |
| Maximum plant health from scratch | Seeds |
| Genetic exploration & breeding | Seeds |
| Convenience & faster start | Seedlings |
| Absolute uniformity | Clones |
| Commercial-scale consistency | Clones |
| Lowest disease risk | Seeds (from trusted source) |
To Summarize
Growing cannabis from seed, seedling, or clone isn’t about right or wrong, it’s about context and what’s the best fit for your cultivation needs and set up. Seeds offer independence, vigor, and full genetic potential, while seedlings offer convenience and ease. Clones offer consistency and commercial precision, but having a reliable source is crucial.
In today’s cultivation environment, where microbial and viral issues are more widely discussed than ever, starting material matters more than it did a decade ago. Don’t forget, every grower will have their own opinion about what is best, but every grow set up is totally unique. The best advice is to choose cannabis clones, seeds or seddlings based on your experience level, your environment, and your end goal.
