SHOGUN Sumo Boost

£37.95 – £219.95 incl. Vat

Select options

SHOGUN Sumo Boost is a heavyweight bio-stimulant without equal. Standing proud as the champion of all yield boosters it triggers rapid gains in yield and quality by initiating a powerful and targeted flowering response. Plant efficiency is maximised to devastating effect, whilst quality, aroma and taste are improved via enhanced essential oil production.

Buddhas Tree Advanced Meta Boost

£40.50 – £144.00 incl. Vat

Select options

Buddhas Tree Advanced Meta-BOOST Stimulates and fuels a metabolic increase in the plant by providing the correct type of energy sources to the plants cells to energise their activity. As we know plants grow and develop by splitting and reproducing their cells. This takes a lot of energy. The plant expends energy converting elements in the nutrient into a form of energy that it can use at a cellular level. Advanced Meta-BOOST provides the plant cells with the best and most usable type of fuel so that the plant doesn't waste energy converting and producing its own. It also allows the plant`s own saved energy to be given over to other areas of its growth such as production of oils, resins , terpenes and sugars giving increases in taste and smell qualities. Meta- BOOST allows your plant to utilise nutrients more completely and efficiently and in turn this stimulates an increase in nutrient uptake having a positive impact on yield and overall quality. Advanced Meta - BOOST is a rich seaweed derived plant bio stimulant that contains naturally occurring levels of various plant growth stimulators including Auxins , Cytokinins and Amino Acids. Auxins are a class of plant hormones that have a primary role in the coordination of many growth and behavioural processes in the plant's life cycle and are essential for plant body development.Cytokinins (CK) are a class of plant growth substances that promote cell division in plant roots and shoots. They are involved primarily in cell growth and organisation, but also affect bud growth, and control the leaf ageing process. Amino acids are required by plants throughout all their growing stages. They have an important nutritional function during the production of important substances within your plants. They are the starting points that the plant uses to produce vitamins, chlorophyll, enzymes, and proteins. Amino acids also act as chelating molecules of essential nutrients for normal development of the plant.

Systemair ‘Carbo Air 100’ High Quality Carbon Filters

£397.99 – £459.99 incl. Vat

Select options

CarboAir 100 has been developed to filter very high concentrations of VOCs from larger grow rooms.

CarboAir 100 has a huge 100mm bed of virgin activated carbon and a 1 metre body. This, coupled to our industry leading steel mesh is the most effective filter in the industry. These filters are monsters, designed for the most demanding environments. if you need to clean very large volumes of air or large amounts of unwanted smells, this is the filter for you.

Removes even the strongest odours
Handmade in Europe
Comes with a machine washable pre-filter
18 month guarantee

VIRGIN ACTIVATED GRANULAR CARBON The virgin carbon is activated at temperatures above 1000°C in a humid environment. The process opens the pores of the carbon to give it incredibly high absorption properties of organic particles and other airborne pollutants. The carbon is produced to very high standards in Europe, unlike Chinese filters which often contain cheaper blends and risk water contamination during shipping. Being produced in the EU enables better quality control.The carbon is produced to EN12915 which means it is pure enough to be used in food and drink applications. The size and depth of our filter has been specially designed to provide the correct contact between the contaminated air and carbon.The carbon is double sieved to remove any dust particles which would restrict air flow. Each CarboAir filter is guarantee to a minimum of 18 months because the carbon is pure.All filters are batch tested at source to make sure it passes our quality requirements. FILTER HOUSING The filter mesh is 55.5% open for the best air flow through the filter. Carboair filters have better flow rates, enabling them to utilise a thicker carbon bed compared to competitors. The top flange and bottom flange are preformed and made of the same strong galvanised steel. The carbon is machine packed as tightly as possible into the housing without crushing the carbon granules. The carbon is placed into the casing and put on tremor plates that have precise frequency to vibrate the carbon into a tightly packed uniform filter. A high density foam collar is placed onto the carbon bed before a top plate is added on top of the foam collar. This is then machine compressed, reducing the foam collar to less than 5mm thick. This unique process ensures the carbon will not move or settle. A top flange is fitted, this compresses the carbon further. The whole process is carried out by hand and visually inspected during each stage. The carbon filters are then packed directly into bags and boxed in the factory ready for shipping guaranteeing you receive the best quality filter every time.It has an industrial galvanised steel filter casing. Using the highest quality materials enabled it to use the finest mesh.

CANNABOOST Accelerator

CANNABOOST Accelerator boosts the metabolism of your plants. This is important, because the uptake of nutrients depends greatly on the plant's health and metabolism rate. CANNABOOST is specially developed for short cycle plant varieties. The advantages of growing with CANNABOOST Accelerator include: Better Yield CANNABOOST stimulates the development of new flowers. Because of this the fruits can become heavier than normal. Since the ripening of the fruits also proceeds more gradually, it results in a more uniform harvest. Something very special about CANNABOOST is that it’s not just a guarantee for higher yields but the taste is also guaranteed to be better. Something extra for the CANNA grower! Suitable for use with all growing mediums and substrates CANNABOOST is a universal flowering stimulator, which is to say that it can be used with any growing system and in combination with any feeding with no exceptions. As well as adding CANNABOOST to the substrate it can also be used as a leaf spray (foliar feeding). The advantage of this is that the plant can absorb the flowering stimulator directly through its leaves. Even higher yields in combination with PK 13/14 CANNABOOST isn’t a nutrient, but an additive that increases the plant’s photosynthesis (one of the reactions that make up a plant's metabolism). This increase ensures that the fruits are formed faster. The availability of nutrients is very important for achieving optimum results with CANNABOOST. The availability of all nutrients is guaranteed with CANNA feeding. Even better results can be achieved using the trusted CANNA feeding in combination with CANNA PK 13/14. This is because PK 13/14 provides the plant with extra flowering elements while CANNABOOST ensures that there’s the energy to be able to use these elements. Better ripening and strengthened immune system CANNABOOST contains flowering stimulators that ensure powerful ripening. It also contains natural flowering regulators that help develop fruit more uniformly and finish flowering more strongly. Thanks to the improved energy regulation the plant also has sufficient energy to resist diseases. If there is no energy at the correct place diseases will often strike, just at the moment when it is disastrous for the harvest. Fuller, more powerful taste With CANNABOOST you are guaranteed both a higher yield and an exceptional taste. A good harvest isn’t just expressed in terms of weight these days. Quality is starting to play a more important role and this also means taste is becoming more important. Increasing the speed of photosynthesis greatly increases the sugar production in the fruits. This makes the taste sweeter and the natural flavours in the fruits will be produced in higher concentrations. The stronger smell of the essential oils in the fruits speaks volumes. Most boosters are just additional nutrients. True boosters like CANNABOOST however really boost the metabolism of a plant and makes it more healthy. CANNABOOST is 'the new boost generation'.
