PRO-XL has formulated a unique growth fertilizer for optimal growing with CO2. After years of testing, PRO-X managed to produce the ideal Nutrients composition for growing with CO2. As the plant grows harder when adding CO2, it is extremely important that you use the proper growth nutrition.

Pro XL Growth Nutrients is suited for use on all types of mediums.

Use: A 250 ml and 250 ml of B per 100 liters.

A & B concentrate Never mix pure (without water)!

Sturdy knife for a SpinPro cutting machine. Much stronger than the standard cutting wire

PK 13-14 is a bio-mineral fertilizer that provides for extra phosphorus and potassium during the flowering phase of the plant. This results in denser, harder and heavier fruits. PK 13-14 ensures a high yield.

Ozone safely alters the molecular structure of offensive micro-organisms, to eliminate odor.

Uvonair is a high output Corona Discharge generator that produces more ozone than any others known at this time. It is adjustable to match the ozone demand load for odor control as well as provide energy conservation in low demand periods.

Striving for perfection is a near impossible task. Nevertheless by creating her new grow booster Grow Sensation No Mercy have realised a relevant step forward. In the different stages of their growth cycle plants require different nutrients. The problem to be solved is that it's impossible to mix many of those nutrients into a standard grow nutrition. No Mercy sought out the assistance of one of the most respected nutritional companies in search off a grow booster that does contain all of those nutrients. And she has succeeded... even more than we anticipated!

We were pleasantly surprised to find out how much a good grow booster could add. No Mercy Grow Sensation is a must for every serious and smart gardener!

Use:
Dosage: 50 ml to 100 l during the first 4 weeks. Add Grow Sensation to the water and adjust EC with your regular nutrient. Then adjust pH to 5.9-6.1. In hydropnic systems pH values should be a little lower. Because No Mercy Grow Sensation is a natural product, the composition can vary slightly depending on batch and season.
 

Two bio-mineral nutrients for the flowering stage. All micronutrients in the mineral part are chelated. The iron is a Fe-EDDHA chelate which enables the plant to use the iron in a wide range of pH values. The biological part contains more than 30 micronutrients, carbon hydrates, amino acids en a vegetable hormone which stimulates chlorophyll production.

Nutrients needed in relatively large quantities are called macronutrients and those needed in relatively small quantities are called micronutrients.Sweet Jane combines main nutrients with biological stimulants

Sweet Jane 1 for the first half of the flowering stage ( NPK 7-7-7 )
Sweet Jane 2 for the second half of the flowering stage ( NPK 2-4-9 )

( So it is not a 2-component nutrient nor a Grow and Flower nutrient. )

The maximum advised dosage for Sweet Jane 1 and 2 is 5 milliliter on 1 liter tap water for mature plants. Use half the dosage for for plants smaller than 30 centimeter. Use the nutrition with every watering.

A standard diagram does not take into account the many differences in substrates . Also the volume of soil influences the additionally required nutrients. Given sufficient good organic soil, you can grow without nutrition at all. Instead the following guidelines will help you to determine the right concentration.

With increased temperatures you must use less nutrients to prevent leaf burn.
If for some reason the plant slows down you must decrease the amount of nutriments.
More soil, means less nutriments.
If you start in rich soil you should water the plants without nutrients at all for at least the first two weeks. The usage of a leaf fertilizer is recommended in the first 10 days to ensure that all micronutrients are available to the seedling.

During the development, different ratios of nutrients are required by the plant. The first weeks the plant will still grow while the flower production is low. This changes during maturation.

Especially when growing on soil we run the risk of giving to much of one the elements N,P or K. Nutrients not used by the plant will remain in the soil. After time the EC (or TDS) value gets to high and salts build up in the soil. This is a disadvantage for the plant because it affects the ability to take up water. Also a large concentration of minerals in the substrate is harmful to the micro-life. This I why the right dosage of nutrients is important to prevent excess salt buildup. You need some foresight especially on soil because it is impossible to flush the nutrients without drowning the roots.

Roots take in water easily when the concentration of nutrients is low, a low EC value. The ion concentration in the plant cells remains higher than the surrounding substrate causing osmotic pressure. Water is pulled into the plant by this osmotic pressure. If the ion concentration surrounding the roots is higher ( high EC) than inside the plant cell, the plant has to make adaptations to be able to take in water. At this point the production looks fine, but the ability to take in water is largely reduced. Raising the EC any further will slow down the plants development.

In short: Feed it , don't store it.
