However, simple preventative measures are advisable rather than finding yourself playing botanist come alchemist at 3 am mixing potions of home brewed fungicide to exterminate microbial nasties.
We’ve got good news and bad news when it comes to effectively purging your cannabis garden of Pythium. The good news is Pythium can be treated and eradicated, the bad news is it’s going to cost and it’s always a high a price to pay to defeat an embedded enemy.
As a root zone parasite, Pythium can often go undetected by the cannabis grower until it’s spread throughout the garden and planning on staying.
Battling a Pythium plague is a war of attrition and even if you eventually prevail the damage caused by Pythium is permanent so the grow will invariably be delayed to allow time for the cannabis plants to regain their vitality and marijuana yields are certain to be impacted negatively.
Hydroponics growers must ensure the water in the reservoir is highly oxygenated, not only to ensure optimal nutrient uptake but also because Pythium perishes in a well aerated medium. Aeroponics cultivators are probably grinning and well they should!
Detecting Pythium in the weed garden can be a real head-scratcher. Outdoor growers and indoor out of the bag soil cultivators are not immune to the blight of root fungus either. In fact, Pythium is even more difficult to readily identify in non-hydro grow ops.
By this time Pythium has already been damaging the plant’s roots for quite a while before the above ground symptoms of unhealthy plants grabs visual attention and raises the alarm.
Healthy root zone development can also be encouraged by supplementing your feeding regime with beneficial bacteria and fungi. These days the 21st-century cannabis cultivator is spoiled for choice when it comes to friendly fungi additives.
Getting your precious little beans off to the perfect start is the first step towards that final lush cannabis harvest. Germination really is an all or nothing affair so we recommend our Royal Queen Seeds Starter Kit, it’s got everything you need to get your grow on including a propagator, rooting medium and of course a choice high quality feminised seeds.
Pythium is a fungus that loves to munch and pollute a cannabis plants root zone. Follow our advice and be prepared to combat root rot in your marijuana crop.
One way we increased the amount of dissolved oxygen available to the roots (to help fight the root rot) was to lower the temperature of the grow room and therefore the reservoir, because water can naturally hold more oxygen at cooler temps.
2.) Deliver more oxygen to roots
In this article, I will share how we were able to remedy a case of cannabis root rot in a hydroponic setup. Root rot is often thought of as being “incurable” and I’ve heard of several cases where growers throw away their cannabis plants that are hit by root rot. I know lots of growers who have tried hydroponic growing, and gave up after running into root rot for the first time.
One of the things I’ve learned is that every grow has it’s own unique challenges. Every time you run into a problem, the best thing to do is learn from your mistakes and use that information to do even better in your next grow.
3 days later – New healthy roots began to grow out of old brown ones
One of our plants was affected only slightly (her roots had slight patches of brown, but she didn’t really show any signs of stress above ground). However, the other plant in the tent was struck much worse. She had recently been transplanted into a bigger container, and we suspect that moving her to a new reservoir may have stressed her out slightly, leaving her less resistant to root rot than her sister who wasn’t moved at all.
In the reservoirs, we could see the plant roots showing signs of root rot.
When the heat rises, the water in the hydroponic reservoir physically cannot “hold onto” as much dissolved oxygen, and the plant roots can more easily become starved for oxygen.
Root rot is a condition that affects the roots of many plants including cannabis, most commonly in hydroponic setups when the plant is not getting enough oxygen to the roots.
