    ECOTHRIVE AND BIOBIZZ OPEN DAY

    Ecothrive and Biobizz Open Day

     

    To beat the inescapable January blues, we’re putting together an expert open day on 29th January 2020 with two companies we’re incredibly proud to stock. 

    We’ll be visited by Biobizz and Ecothrive on Wednesday 29th January, wherein reps from each company will be available to offer best-use advice on their full range of products, as well as extra information about what actually goes into the products you’re using on your plants. 

    You can expect free samples, expert knowledge from the people who actually make the products you’re using, and a chance to chat to other growers interested in organics and natural alternatives to some of the other additives and nutrients out there. 

    Both Biobizz and Ecothrive care massively about the ingredients, the benefits, and the science behind what they create and sell, and we hope the collaborative open day will be an excellent chance to learn a bit more about how these products can help your grow room to thrive. 

    If you’re not sure if the open day’s for you, here’s a little bit more about the two companies:

    BOTANICARE BRAND SPOTLIGHT

    Botanicare Brand Spotlight

    Botanicare is a leading brand of plant nutrients, additives and supplements, world-renowned for their commitment to the science of plant growth. 

    The original Botanicare product! Here's where it all began. Pure Blend Tea contains all the required components for maximizing both the flavours and the aromas of your plants. You'll find: vitamins, enzymes, amino acids, ultra-soluble humates, fulvic acid and carbohydrates packed inside to give your plants just what they need. The formula is completely water-soluble, and delivers excellent performance in soil and hydroponic gardens.

    Pure Blend Tea

    Meet your plants' metabolic demands through bloom with the Botanicare Sweet range, including Raw, Grape, Citrus and Berry. Sweet is intended to enhance and bring out the natural scents and sweet tastes of your plant, but will not alter or modify these in any way, only strengthen them. This is done by increasing the production of terpenes and essential oils. As with Pure Blend Tea, the Sweet range is water soluble and fine to use with hydroponic systems as well as soil.

    VPD - VAPOUR PRESSURE DEFICIT

    VPD - Vapour Pressure Deficit

    As implied by the word "deficit" we're talking about the difference between the theoretical pressure exerted by water vapour held in saturated air (100% RH at a given temperature) and the pressure exerted by the water vapour that is actually held in the air being measured at the same given temperature.

    In essence, it is the consequence of the imbalance between temperature and relative humidity.

    ⬇︎LOW Humidity + ⬆︎ HIGH Temperature = as air warms it expands and has the ability to hold more water

    ⬆︎HIGH Humidity + ⬇︎LOW Temperature = as air cools and contracts vapour concentrates and can fall or condense out of the air as water

    Temperature control and humidity maintenance are essential for the prevention of VPD. There are several ways to monitor your grow room and ensure these optimal levels (see table) are maintained.

    To learn more about humidity, check out our humidity blog -

    There are several products you can get to manage your humidity levels.

    WINTER WARM UP

    WINTER WARM UP

    As the temperatures drop, your plants will need extra warmth. Cold damage is not always easy to spot, and many growers may misdiagnose it as a disease or deficiency. The most common cause is temperatures falling overnight, inflicting mild cold injuries on sensitive plants.

    What happens

    As the lights in your room go off the temperature in you grow room can plummet, this is bad on many levels.

    1  The heat in you room drops significantly and quickly this shocks your plants and can stop them feeding losing yield.  Temperature of your grow room over night or when lights are off is also crucial for when lights go back on, humidity can increase due to the quick increase of temperatures and your plants don’t start feeding straight away as the root ball is so cold this loses you time and yield. 

    REMEMBER YOU DON’T WANT MORE THAN A  6°  TEMPERATURE SWING BETWEEN DAYTIME AND NIGHTTIME CYCLES

     

    2  humidity in your grow room will also shoot up.  If you are in flower when this happens it could give you problems with Botrytis also known as bud rot causing you to lose yield.   

     Plant deficiencies can be mistaken for cold temps, this is a night mare as you could end up spending money on products that you don’t need trying to fix a problem that could be fixed by buying the correct equipment

    Cold Damage Symptoms include:

    • Wilting
    • Leaf curling
    • Discolouration
    • Damaged spots

    HUMIDITY: THE WETTER THE BETTER?

    Humidity: the wetter the better?

    Humidity has a huge impact on plant growth, the guttation seen here as droplets on the tips of this leaf are a visible indication of an excessively high (night-time) humidity

    There are many aspects to the environment that you can play a part in controlling. Temperature is usually always the first on people’s minds, we can feel heat so naturally it becomes quite a significant factor to us humanoids. If you hadn’t already guessed from the title of this blog, the second parameter on the hypothetical list should be humidity. The amount of water in the air doesn’t really impact people very much (other than say give us a tickly cough or make us overly sweaty) but for a plant it is a completely different kettle of fish.

    Understanding your humidity means not just understanding humidity on its lonesome though. It is intricately linked to temperature and has multiple impacts on plant growth, so it takes a small amount of getting your head around to properly understand, but once you have the basics it will help you out leaps and bounds down the line.

    So, what is humidity

    Quite simply, it is the amount of water in the air. Strictly speaking, ‘Relative Humidity (RH)’ is what a grower measures though, and by relative we don’t mean uncle dickhead who turns up to ruin Christmas. The ‘relative’ bit is referring to temperature. The warmer the temperature of the air, the more water it can hold. What does this mean though? Well, imagine you had a sealed grow room that was 20°C, with a relative

    TEMPERATURE IN THE GROW ROOM: MAN’S NOT HOT!

    Temperature in the Grow Room: Man’s not hot!

    Us humans deal with hot temperatures differently to that of our plant friends

    Temperature is THE most important thing for your indoor grow room. Underestimate temperature issues or do not adequately control your temperature throughout your grow, and you will never achieve the record-breaking yield of your dreams. One or two extra degrees of heat during warm days, too cold a night time temperature, or even too great a swing in your day/night temperature difference all play a direct part in adding to your yield. Getting them right will see more of an addition to your yields than any bottle of nutrient can give you; quick maths.

    Understanding how temperature impacts your plants and understanding how you can steer your growth by controlling grow room temperatures will quickly set you on the path to becoming a hydroponic god. This blog is a quick insight into temperature and a few pointers about the sort of equipment you can use to control it all. So, without further ado, let’s get cracking!

    What temperature does

    There are two key things that temperature impacts a plant with; its metabolic rate and its cooling capacity, which are essentially at constant logger-heads.

    Your plant needs heat to maintain a healthy metabolism. Eve
