    Identifying and Treating Grow Room Pests

    It's likely that however well you run your grow room, at some point, you'll have to deal with grow room pests. Pest sprays and insecticides can be worth looking into for severe infestations, but in many cases, it’s possible to use a natural biological control (predators) to get rid of your pests and return your plants to health. 

    The first step to treating your grow room pests is to identify which pest is plaguing your plants. In our experience, the most common pests are Red Spider Mite, Thrips, Sciarid Fly (Fungus Gnats) and Aphids. We’ve put together a guide on how to identify the various pests you may come into contact with, and how to treat them.

    How Do I Know if I Have Red Spider Mite? 

    Spider Mites are really small insects which grow to around 1mm in size. Spider Mites thrive in warm environments with low-to-medium humidity, and have a short reproductive cycle. From egg to adult takes about 14 days at 21°C, and less than a week at 30°C.

    Using a magnifying loupe will help you to see them a little clearer. With a smart phone, you can see this with our Phone Scope.

    The first signs of a spider mite infection is leaf damage, a fine pale mottling on the upper leaf surface. The u

    How to Dechlorinate Your Water 

    When you’re watering your plants, it may be tempting to reach for the kitchen or garden tap and use straight unfiltered tap water. Unfortunately, the various elements in tap water will interfere with your plants’ absorption of nutrients and supplements, and stunt your potential growth and yield. Using fresh tap water on your soil or growing media will kill a number of microbes in the root zone, primarily throughout the top ⅓ of your pot and your surface area.

    The most common problem you’ll encounter with tap water is the chlorine present. Plants are able to absorb chlorine, but they only need very minimal quantities, and you shouldn’t ever need to add any. Watering or irrigating with tap water will over chlorinate your plants. Over chlorination will result in reduced growth and yields. On average, tap water in the UK has a 0.5mg/l of chlorine. Water companies attempt to meet this standard, but it can vary slightly either way, up to around 1mg/l.

    In addition to chlorine, tap water also contains chloramines. Chloramines can be even more damaging to your plantlife than chlorine. Chloramines are typically used as water sanitizers, and contain chemical compounds of chlorine and ammonia.

    What Are Your Options?

    Allow Your Chlorine to Evaporate Naturally

    While it may not be the quickest or most exact method, if you leave your water (either in a bucket or a tub) uncovered and in a well ventilated area, the chlorine will evaporate over time. The time needed for this method to be effective will be entirely dependent on the size of your receptacle and the amoun
