Definition of 'BUD ROT'
Also Known As:
Bud rot also known as Grey Mold and Botrytis Cinerea can spell disaster for a grower and his crop. Bud rot can affect both indoor and outdoor grows but is most common in a grow space that has high levels of humidity. It can initially be hard to spot grey mold and by the time you do you have a full blown infestation. Bud rot can also affect cannabis that is curing or drying. Bud Rot affects marijuana when the humidity is high and the temps are low. In particular it affects buds in the last 50% of the flowering phase. Bud rot can be largely prevented by making sure to keep humidity low and having high air flow while your plants are budding. Also keep the humidity as low as possible for the strain. Water your plants when the lights are on and the room has heated, also avoid getting water on the buds by watering the soil medium itself, do this by watering in small amounts so the water is absorbed quickly. It is best to water 2 times with a few hours between each water, than to do one big water all at once.Identifying Bud Rot:
Bud rot starts out in the densest buds and turns then to mush from the inside out. The bud becomes brown looking on the inside and the outside of the bud is still green, it can also have a white or grey film over it, this is the mold itself. Also it will often smell moldy as the spores are produced by the budrot.
Removing and Treating Bud Rot:
Do not try to save the bud it is on, it is to easy to spread the fungus spores to the rest of your grow. To remove bud rot you need to place a plastic bag over the infected bud and then close the bag and seal it,then cut of the infected bud. Make sure to keep the bag closed and then throw it away. DO Not let the mold spores out into your home or grow space, the nasty little buggers will then easily infect more plants in your grow. If you need to save as much marijuana as possible find a place far away from your grow spot and then use scissors you disinfect before each cut in 3-5% h2o2 solution, trim of the unaffected part of the bud, make sure to dispose of the infected part and then wash your hands in a 3-5% hydrogen peroxide solution, this will kill the mold spores. Also wash all equipment you used to remove the infected buds eg scissors. Also you need to make sure you have low humidity in your grow, make it as low as your strain will tolerate, plus make sure to have good air circulation, put in extra fans if you can. You can also get air purifiers which use ultra violet to kill air born mold spores, this has helped a lot of growers, we recommend every grow to have these in their grow it is a great way of preventing issues. Also do not foliar spray as this will help it grow and spread.
