Seedsman’s Halloween Promotion
Before we go any further, thought you should know our 2022 Halloween Promotion is now live. Not only are we offering incredible specials on world-famous cannabis seed banks, we’re also giving away 2x Freakshow Seeds with every order!
Anyway, where were we…
Spooky season is upon us, and if you’ve timed your grow right then, you could be enjoying a nice baggie full of Purple Ghost Candy on Halloween night.
However, as every cultivator knows, things don’t always go to plan, and plants are sometimes struck down by miniature ghouls or other malevolent forces. Fortunately, the curse can often be broken by tweaking a few basic parameters… unless your grow room is haunted.

Seeds Not Germinating
Cannabis seeds failing to sprout can put the wind up even the most seasoned grower. Luckily, there’s no need to fear if you’ve sourced high-quality seeds from a top seed bank, as poor genetics are the number one reason for seeds not germinating.
Trying to grow a bunch of mystery seeds you found lurking in a baggie is therefore, unlikely to yield many plants. On the other hand, the seeds in the Seedsman catalogue are all proven to have excellent germination rates.
Of course, even the best seeds still require proper handling to fulfil their potential. Contamination with certain bacteria or fungi can inactivate some seeds, which is why they should never be touched with bare hands. Too much or too little water can also block germination, as can excessive cold or heat.
Plants Not Flowering
Photoperiod cannabis strains need a certain amount of darkness to switch from veg to flowering. As a general rule, changing to a 12-hour photoperiod should initiate the flowering stage, so don’t be afraid of the dark and make sure you cut the lights in your grow room.
In most cases, a failure to bloom is caused by cannabis plants not receiving enough hours of darkness, although other factors are sometimes to blame. For instance, cannabis needs nutrients like phosphorous and potassium to produce flowers, while nitrogen is more important during the vegetative stage. Providing plants with the wrong nutrients at the wrong time can impact their ability to move smoothly from one phase to the next.
Most terrifying of all, though… you might have MALE plants!
Nothing looks as sad as a cannabis plant with drooping leaves. Often the slump is the result of either overwatering or underwatering, so it’s important you give your plants the right amount to drink.
Overwatered plants can become starved of oxygen as their roots get waterlogged, while underwatered plants dry out and lose their perky vitality. Fixing the problem is easy enough as long as you don’t let it carry on for too long, and plants often recover fairly quickly once they are given the correct amount of water.
An ethereal coating of spider-like webs not only looks spooky, it could spell disaster for your cannabis plants if it isn’t dealt with quickly. The unmistakable calling card of the dreaded spider mite, these webs mean you’ve been visited by one of the most common – and annoying – villains in the cannabis pest roster.
Despite being tiny, these voracious bugs are prolific reproducers, so it’s essential to exorcise the little demons before they get a chance to establish themselves properly. Like vampires, they feed on plants by sucking the nutrients out of the leaves but can be defeated by a simple change in atmospheric conditions.
Lovers of warm, stagnant air, spider mites can’t stand a cool breeze, so increasing airflow and lowering the temperature are your best defences against the little creepy crawlies. Predator bugs like ladybirds and natural pesticides like neem oil can usually take out a fair few mites too. However, you will have to prune any affected leaves and may even lose entire plants if you act too late.
Ghostly white patches appearing without warning on cannabis plants can be enough to make the hairs on the back of most growers’ necks stand on end. This unmistakable apparition can be none other than powdery mildew, a fungal infection that drains the life force from anything it lands on.
The spores flourish in humid conditions but can’t settle unless the air is still. A dehumidifier and a fan are more effective than holy water at keeping this evil spectre away.
If it’s too late and you’ve already fallen into the mildew’s grasp, however, then your best bet is probably to spray your plants with milk or potassium bicarbonate dissolved in water. Sadly, infected leaves will have to be discarded, and some plants may be lost if they have too much powdery mildew on them.
Sinsemilla is every grower’s goal, which means pollination must be avoided at all costs. Once fertilization occurs, plants start diverting more energy into producing seeds and less into making cannabinoids or terpenes. Just one sneaky male is all it takes to completely wreck an entire crop, so it’s essential not to allow any pollen monsters into your grow space.
Plants usually display their sex shortly before flowering, when females develop pistils while males grow pollen sacks – often referred to as ‘bananas’. Unless you’re planning on breeding your plants, you’ll want to remove any males before they can release their pollen and fertilize your females. Alternatively, you could stick to feminized seeds and never worry about males and their evil intentions again.
There’s nothing worse than weed that’s full of seeds, so if you’re looking to play a particularly nasty trick on someone this Halloween, why not sneak a male plant into their grow room and let havoc ensue?
Speaking of sex, some plants actually go both ways if conditions aren’t right. Hermaphroditism occurs when a plant is so stressed out by its environment that it thinks the only way it can survive is to grow male and female organs so it can pollinate itself.
Growers should always be on the lookout for unexpected bananas that may pop up on a female plant. Plants that become hermaphrodites should immediately be removed from the growing area to prevent the possibility of pollination.
Fortunately, hermaphroditism is rare when conditions are maintained within the optimal range, so the best way to avoid this terrifying outcome is to ensure your plants have a hospitable environment. By regulating temperature, lighting, humidity, soil pH and nutrient supply, the possibility of disaster can easily be averted.
Now there are two words that fill all growers with horror. Bud rot can ravage an entire crop and destroy months of work if it’s not spotted and dealt with immediately.
First appearing as a white fuzz before developing into black spots, bud rot is a fungus that rapidly spreads from flower to flower. The good news, however, is that spores can’t settle unless the temperature is low, the humidity is high, and the air is stagnant. Taking measures to ensure decent airflow while also supplying heating and controlling humidity levels is, therefore, all it takes to prevent this nasty pathogen from striking.
However, if any plants show signs of bud rot, get them out of your growing space pronto so that the fungus can’t spread to other plants.
Insufficient lighting, nutrients, or water can all stunt plant growth and result in low cannabis yields. Equally, soil pH that is too high or too low can cause nutrient lockout, preventing plants from accessing the nutes you feed them and hindering their development.
Growth can also be curtailed by stress, which often results when plants are subject to shock. For example, heat shock or temperature shock may occur if grow lights are placed too close to a plant’s leaves, while excessive pruning can also create considerable stress.
While it’s true that light stress techniques can encourage plants to produce more THC, CBD and other cannabinoids, overdoing it can have the opposite effect and leave you with a frighteningly small quantity of bud.
Imagine caring for your plants for months before delicately harvesting and patiently drying your bud, only to find it tastes rank. It’s a scary thought, but that’s what happens if you fail to cure your weed properly.
Curing helps to remove excess sugars and chlorophyll while also allowing the terpene profile to mature, resulting in a more desirable aroma and flavour. Some impatient growers try to skip this vital step – which usually takes about four to eight weeks – but are often left horrified by the taste when they spark up.
