Review: Phenomenal Terpene Enhancer, Flower Density Increaser, and Definitely Signals Plants to Bulk up a - As a quick aside to Daniel Thomas’ review below, nitrogen is definitely not useless in flower. Less is used, but there’s a reason that leaves yellow towards harvest time and that’s because the flowers are bulking and ripening and need the nitrogen, a mobile nutrient, much more than the plants. Not to mention they need nitrogen during stretch and certain cultivars also like to have more nitrogen during flower. It’s a myth that it’s completely useless during flower. Most bloom nutrients have some nitrogen. PK or bloom boosters don’t tend to, but that’s why they’re not called NPK boosters. Anyways, this is a phenomenal product. Kicks Terpinators ass. I haven’t used that stuff in a long time. It definitely also helps to dense up your flowers during the bulking and ripening, and definitely helps to break down Mono-terps into Sesquiterpenes. Although this also happens during the cure. I still use molasses and some other carbohydrates as well as this. I think that the variety is good for the microbes and thus good for the plants. Especially when growing organically, which most True products are, the plant is drawing different microbes into the rhizosphere at different points, and so I think the variety helps to ensure there’s plenty of what the plants will need at any given point. While I use living organic soil which can use water only, I still use a few additives, Signal and Terpenez included. As well as a few other True products. And I use Canopy as my main foliar during Veg, rotated with IPM foliar sprays and some other nutrient foliars. I use teas three times a grow. Once halfway through Veg I use a Veg tea, then at 2 weeks into flower and again at 6 weeks I use bloom teas. I also continue to add microbes weekly, and carbs with every other watering, mixing it up. But I definitely use Signal at 2 ml/gallon from halfway through flowering on. I also use True’s Organic Cal-Mag since almost everyone has a Magnesium deficiency and doesn’t realize it. And extra Calcium can’t hurt. Lastly, I bought my True bottles about a year ago and contacted the company since the bottle says to use within a year. They said that as long as it’s stored in a cool, dark place, they should last 3 years or more. He said that the nutrient mixes are pretty stable. Just thought that would help some people out. Happy growing!
Review: The purpleness! - Awesome product to bring out the colors in your plant! It says right on the bottle that this product enhances the genetics IF the plant has them, and 💯 right on the money! My picture is same strain, 2 phenos. Signal was used in both plants as recommended and the results are stunning! Cannot wait to try this on Berry Bomb! As far as increasing density goes, I honestly have a hard time telling if this actually worked or not. I make no claim to be the biggest bud grower, and I did not grow a control plant. I grew 4 plants, same strain, giving 2 honey chome and 2 signal. I will have to update later with taste results after the Signal plants cure up a bit. Until then, I gave a basic rating.. the smells are strong, but not sweet like I get with honey chome. Could just be the strain though. My recommendation; know your plant before you use this product! Clone her a few times to see if purple expresses itself in the plant, then enter a grow competition!

I may not be the best to review this because I never used anything else to compare it to but from my perspective it is causing more bud growth and is not hurting the plant in anyway. I'm watering with it once a week and using it in a sprat bottle for the leaves about every other day.
