How and When to Plant Marijuana
Many people aren’t really sure when to plant their crop. When’s the perfect time of year to germinate your seeds so that everything runs as smoothly as possible? Well, this depends on what medium you’re growing in, the accessories and things you have at your disposal etc. You can grow the perfect crop at any time of year depending on how you’re doing it and what you have. Today we’re going to show you techniques so that you can get the absolute most out of your plants regardless of what time of year it is.
How and When to Plant Marijuana Outdoors
If you’re looking for normal marijuana plants (2m 500mg +/-)
When spring arrives we all know that it’s time to start germinating your marijuana seeds for your outdoor crop. It’s the most important crop of the year as it’s where you can get the most production of the entire year. Old school growers like to plant their seeds for the first full moon of March.
The reasoning behind this is so that while your seeds are germinating they’ll also have light at night time and they won’t stretch up too much in their first days of life. Sometimes it’s a bit too cold at that time though, and of course you can’t plant at the same time everywhere, we’re talking from a Spaniard’s point of view here. If you live somewhere with a very cold climate your plants will take much longer to grow and they’ll get stressed out from cold or wind, which will create weaker plants that are more susceptible to infestations and fungi.
The best thing to do in this case is to wait another month or two; a germinated seed in a decent climate from April onwards will actually be bigger and better grown than one planted in March in the same place.
Taking care of plants for such a long time is quite a lot of work for the grower, you need to keep an eye on infestations, fungi, nutrition, transplants, pruning, tutoring… The whole process takes about six months of constant work. If you’re looking for a decent product and yield, you’ll need:
- Fertilizers for growth and flowering. You can use your preferred fertilizers, organic hummus, guano for growth, a booster for the flowers and a base fertilizer for flowering should be enough to get a productive and flavorful plant. If you use chemicals then you’ll need a complete range from a specific brand that’ll give your plants the minerals they need to make the most out of the flowers. Of course, chemical products reduce flavor but increase yield, whereas natural products intensify the flavor but make for a lower yield.
- Insecticides for insects like white flies, mites or thrips. Preventive insecticides are recommended to avoid any scares.
- An anti-fungi product that works well against oidium. Propolix or other chemical products work well, but you’ll need to use it from the start.
- Bacillus Thuringiensis; this is used for caterpillars and other worms. Use it as soon as flowering begins, which is when these pests start to appear. Around May/june.
- Stakes or wires to keep the branches up during the flowering period.
If you’re looking for small plants (1m 250g +/-)
If you’re looking for some small to medium sized plants, both compact and strong, then you’ll need to wait till around the middle of March to germinate your seeds. Your plants will have about a month to grow before the light period changes, and they’ll grow with more sun than other plants, making for strong and compact specimens. So, when they begin to flower they will be more compact, around 1m tall. You’ll need the same products as for large plants, as well as patience although less due to the fact that they take a lot less time, around three and a half months. This style is much easier for beginner growers, although you’ll still need to take care of them.
If you want gigantic plants (3m 1kg+)
To get these kinds of plants you’ll need to apply yourself to the job more than the other two types. You’ll need to grow plants with a decent size so that they can grow amazing 2m long branches in all directions with buds as thick as your fist that you’ll need to hold up with a SCRoG mesh so they don’t break.
If you’re looking to grow a plant of this size before June then you’ll need to grow it for at least six months so the plant has more surfaces to flower on, which should take another three months. You’ll get much better results if you plant straight into the ground rather than pots.
To be able to grow it for so long you’ll need to do so in a greenhouse. You’ll need to buy or make your own plastic greenhouse. In a greenhouse your plants can avoid the cold during the winter as well as receive enough light to grow properly. You’ll need to germinate your seeds in December. You should germinate them inside so that they don’t die off at the start and they can get a nice warm germination.
Then, you’ll need to make a hole around 50x50x50cm and fill it with new substrate so the plant has a decent medium to grow in. Once your plant has germinated and it’s a few centimeters tall you can officially move it to the greenhouse. You’ll need to install a light above the plant that should turn on for 10 minutes every four hours or twice a night so that it still grows during the winter. The light doesn’t have to be super powerful, the only reason we do this is to annoy the plant and keep it growing. Once the plant reaches around 40cm, you’ll need to start pruning it starting with the main calyx. Two or three weeks later, prune again on the higher branches, two weeks later another one… until after a couple of months you have a big ball of leaves full of mini-calyxes which will later grow into long branches.
More or less around February you’re going to need to place four stakes around your plant in a 1mx1m formation, with the plant right in the middle, and then place a SCRoG mesh over it to separate the branches as much as possible and as wide as possible. Once March arrives you’ll need to take the light away and let it get used to natural light and the growth period lighting (these dates are for Spain). Once you notice the good weather starting again, sometime near April, remove the greenhouse and let your plant breath fresh air. Your plant will be a meter tall, when everyone is is still germinating at this stage, which a whole lot of branches and prepared to grow for another three months. Once June/July arrives, your plant will be absolutely huge. Just before it flowers you can place another mesh so the branches can put up better with the weight of the buds. You’ll need to keep an eye out for infestations and fungi due to the size of the plant and how hard it can be to inspect all of it. It’ll need good nutrients due to how long it’s going to grow, and you’ll need to water it properly. You can get the entire years’ worth of gear in just one plant. Happy growing!

Growing Cannabis Outdoors In The UK: Month-By-Month Guide 
Don’t let the heavy rain and seasonal humidity put you off. It’s perfectly possible to raise a healthy and vibrant crop of cannabis plants outdoors in the UK. Follow our in-depth guide below to find out how.
A complete month-by-month guide to growing cannabis outdoors in the UK.
Growing outdoors comes with a unique set of challenges per location. Everything needs to be considered, from local pest species to the best strain for the job. Simply follow the growing guide below to boost your chances of a successful outdoor harvest in the UK.
GROWING CANNABIS OUTDOORS IN THE UK IN 2021
Growing cannabis outdoors in the UK usually involves (at least) one consistent weather condition: rain! Your plants will rarely go thirsty or wilt from the heat. The UK experiences a temperate climate defined by cool, wet winters and warm, wet summers. The country rarely experiences extreme weather events, although flooding and droughts do occur from time to time. The UK sees an average of 133 days of rain and around 1,350 hours of sun per year. This fine balance of rain and sun gives plants plenty of the key resources to develop properly.
The UK features four climate segments:
• South-east: This region experiences cold, biting winters along with warm, dry, and pleasant summers. Continental winds keep things relatively dry in general. South-east UK encompasses London, Brighton, Cambridge, and Norwich.
• South-west: This area of the country sees mild and very rainy winters contrasted by warm and wet summers. Tropical winds from the south extend the growing season. Includes Cornwall, Devon, Bristol, and Cardiff.
• North-west: The north-west experiences mild winters and cool summers. Maritime winds bring a whole load of rain all year round. This region covers Northern Ireland, northern Wales, and western Scotland.
• North-east: Arctic winds from the north bring cold winters, cool summers, steady rain, and a shorter growing season. Includes Newcastle, York, Edinburgh, and Aberdeen.
IS WEED LEGAL IN THE UK?
Unfortunately, the United Kingdom is lagging behind more progressive European nations when it comes to cannabis legislation. The government categorises cannabis as a class B substance, meaning mere possession can lead to a maximum 5-year prison sentence, an unlimited fine, or both. Growing and supplying cannabis can lead to the more extreme punishments of up to 14 years in prison, an unlimited fine, or both.
Despite the draconian nature of UK cannabis laws, things are improving. CBD products are widely available over the counter in stores, so long as they possess no more than 0.2% THC. The government also allowed doctors to start prescribing cannabis products to patients in 2018. In 2019, the NHS received the all-clear to start prescribing cannabis-based products for Lennox–Gastaut syndrome and Dravet syndrome.
The UK has a long way to go to match the more relaxed approaches of certain American states and European nations.
A GUIDE ON GROWING CANNABIS OUTDOORS IN THE UK
Below, we’ll generalise and focus on the south-east, south-west, north-east, and north-west, while touching on specific locations along the way. It’ll help if you do a little more research on your specific area just to make sure you have all the bases covered.
• Day length March 1st: 10h 57m
• AVG temperature: 3–10°C
March marks the official start of spring. However, things are still pretty chilly in most of the country. But this doesn’t mean growers can’t get a head start indoors. Start germinating your seeds and placing emerging seedlings under LED lights or on a sunny windowsill.
Start weeding your beds and dressing them with high-quality compost. Layer them with straw or wood chip mulch to trap moisture and prevent weeds from returning. If you’re growing in containers, dress them with good compost, too. Start cleaning out and preparing your polytunnel or greenhouse, if you’re lucky enough to have one. Scrub down any algae from the glass panels, brush out debris, and get it ready to host your cannabis plants in the coming weeks.
Certain microclimates around the UK allow lucky growers to plant outside during March. Cultivators in the Scilly Isles, Anglesey and Dungeness usually see the last frost around late February.. Pay close attention to the forecast and decide whether the risk might pay off. Make sure to keep a backup crop growing indoors just in case.
• Day length April 1st: 12h 59m
• AVG temperature: 5–13°C
April brings a significant improvement in weather and sunlight. Bluebells, wild garlic, and other aromatic spring flowers lead the charge of emerging plant life. Although April brings a nice, warm heat, frost still poses a significant risk. Growers in most regions will need to keep their plants indoors under lights and on windowsills for a couple more weeks to be safe. However, cultivators with greenhouses or polytunnels will be able to safely move their plants to these structures during April.
Only water your seedlings when the top inch of soil dries out, being careful not to overwater. Head out into the garden and keep the “bad weeds” under control. You’ll be able to sow hardy companion plants during April, such as peppermint, yarrow, coriander, and marigold. These plants will start flowering in the coming months, helping to distract pest insects and attract beneficial ones. Take a stroll around your beds, look out for weeds, and remove them by hand if you stumble across any.
