How Rhizo Blast Works

Healthy roots are the driving force behind healthy crops. Rhizo Blast gives root systems everything they need by utilising a list of ingredients that have been selected for their growth stimulating properties. It contains a large dose of chlorella-based micro algae that's been selectively bred to maximise levels of nutrition. This algae has been treated to ensure that the outer walls of the cells are lysed (exploded), making the nutrients inside even more available than usual. The seaweed found in Rhizo Blast contains an excellent source of nutrients and trace elements, not to mention an array of powerful bio-stimulants.

Using Rhizo Blast will have a massive impact on the development of your plants right the way through, but particularly during the vegetative stages. By increasing the pace of root development, you can decrease the time it takes to get your plants ready for flowering, improving turnaround times. Rhizo Blast also helps to reduce stretching by shortening the length of internodes (the gaps between areas of growth). Plants with shorter internodes make better use of space, making your grow room more efficient.

How To Use

How to Use Rhizo Blast

Rhizo Blast can be used as soon as cuttings start to show roots. Stop using it after the third week of the flowering cycle. Add it your nutrient tank at a rate of 0.5ml per litre. See the attached feed chart for more information.

Unlike some other root boosters out there, Rhizo Blast won't cause anaerobic bacteria issues when the resulting nutrient solution is aerated with an airstone. Note that it will raise EC levels slightly, so factor this in when administering nutrients. You can also use Silver Bullet or H202 alongside it without reducing any of its potency.

As with all nutrients, boosters and additives, never mix them together in their concentrated form (i.e. straight out of the bottle). Always add each nutrient, booster or additive to your reservoir or feed water in turn, giving the solution a good stir to mix it in before adding the next one.
