General
What is the easiest growing method for beginners?
If there was just one, the rest wouldn’t exist. Generally, it begins with a pot, an inert growing medium and a watering can or self-watering system. The best way to start growing indoors is to buy a good grow guide and get an idea of what appeals to you. Equally, your local hydroponics shop will be staffed by people eager to get you growing successfully.
What is a substrate?
Essentially, it is any medium (or media in plural) in which plants grow. Soil, coir, peat, perlite, and rockwool are the most commonly used substrates or growing media.
Do you make a finishing product?
Yes! Dragon Force is an amazing finishing product. We recommend you use it on its own, rather than alongside any other products.
My PK Warrior has a very distinctive aroma; is this normal?
Yes, this is perfectly normal for PK Warrior. Sulphates naturally off-gas and build up under the bottle lid. If you leave the lid off, they’ll eventually dissipate.
Can I use H₂O₂ (hydrogen peroxide) with your products?
It’s fine to use alongside all our products, apart from Zenzym.
Can I use Terra Grow on my lawn? I’m repairing some patches.
You can indeed use Terra Grow on your lawn, but if you have patches then it would be best to reseed them first.
What is the shelf life of SHOGUN products?
Unopened and kept in warm, temperate conditions all of our products can last for several years.
I want to try some products; can you please send some samples?
Our 250ml bottles offer growers the chance to try out our products individually, or give our multipacks a go for the chance to see the full range in action. We partner with large scale commercial operations in some cases; so please email us if you’re interested in a partnership.
PH + EC
What is the importance of pH measuring?
Measuring pH is essential as it affects the availability of nutrients to plants. We recommend a pH between 5.5 and 6.5.
Why do I have to pH test my plant’s water?
pH levels can change dramatically due to a number of factors, including the quality of the water you’re using. Testing the runoff water can give you an insight into any problems your plants might be having in taking up nutrients.
Why do I need to maintain pH levels, particularly when adding nutrients like silicon and calcium?
High concentrations of silicon will precipitate out of a solution at low pH. Calcium is the opposite, precipitating at a pH above 7. It’s important to find and maintain a balance. Diluting your nutrients in 1L of water before adding them to the tank helps to prevent precipitation from occurring.
Does PK Warrior balance pH?
PK Warrior does not balance pH. With the nature of the formulation, it will increase pH marginally and may or may not need adjustment thereafter (depending on the water supply). Once all liquids are diluted with water, the final step is to check the conductivity and pH and adjust where necessary.
I'm using PK Warrior and I'm finding the pH level in the reservoir drops over the course of about 36 hours from 6.1 to 5.5. Is this normal?
It’s perfectly normal for this to happen. When you add PK Warrior, the potassium requirement increases relative to the other nutrients. The uptake of potassium can cause some pH reduction, but this will slow down as you move into week six.
What is EC?
EC is a measure of electrical conductivity. Low EC indicates a low level of available nutrients and vice versa.
What is the highest safe EC for a foliar spray?
The EC of Geisha Foliar is 4.0, which is perfectly safe if applied correctly.
What should the EC be for a CalMag foliar spray?
At 10ml/L the EC should be 2.4 (24CF).
In soft water with a background of 0 CF.
At 15ml/L the EC should be 3.6 (36CF).
What’s the difference between the CalMag and Geisha Foliar sprays?
CalMag is a nutrient based application that supplies calcium and magnesium, improving nutrient uptake and translocation. Geisha Foliar enhances and initiates flowering receptors, increasing the production of flowers.
They are two very different products that can be used in conjunction for maximum effect, although it’s better to alternate their application rather than applying them both at the same time.
Your feedcharts say to drop the EC level in week five of flowering, but most other charts say to drop it in week six; why is that?
Our feedcharts recommend dropping it at this stage because it’s the point when vegetative development stops. The demand for nutrients is higher when the plants are developing stalks and foliage but reduces when vegetative development comes to a finish. It is only a guide though and some plants have longer flowering periods. What is important is that when the vegetative stage stops, you need to reduce your nutrient levels.
