Buyer’s Guide and FAQ

Bloom booster is not a basic fertilizer, more like an addiction that is focused on the development of sustained and healthy flowering. They contain phosphorus and potassium as the core ingredients.
There are 3 different forms of bloom boosters.

They may be liquid, powdered, or granulated. The granular plant food is added in the first stages of growth, so the plant receives needed nutritions in the process. The advantage of such fertilizers is that you sprinkle it just once in 3-4 months or even once during seeding.

The usage of liquid and powdered boosters is different. You need to mix a certain amount of chemicals with water and pour it according to instructions or desired effect. I mean that you may add the mixture every other day and stop nurturing when the leaves start to change color to the darker shade.

3 types of booster exist — pre-flowering, flowering, and final-flowering stages of
weed booster.

  • The first type is for usage when the first bugs are just growing. You may use the Jack’s Classic Blossom Booster or the Maxicrop Soluble Powder.
  • The second stage requires frequent watering during the growing period. Pour plants with the BioThrive Plant Food or the Element Flower Fuel.
  • At the final stage, you can double the number of flowers with the Grow More Hawaiian Bud or Tiger Bloom from the FoxFarm Liquid Nutrient Trio.

Also, you should distinguish organic and chemical nutrients. The organic nutrients come from vegetable and animal waste such as seaweed extract, glacial rock dust, feather flour, etc. The prominent feature of such natural fertilizer is that it keeps soil healthy and can be used repeatedly for decades on the same ground.
Other benefits:

  • the balanced nurturing;
  • protection from burning as a result of overfeeding;
  • improvements in the quality of soil;
  • prevention from the nutrient run-off.

Meanwhile, the insects and even bigger pests love to eat plant food. Besides attracting unwanted animals, there is a list of organic fertilizer related problems:

  • slow absorption;
  • dependent on the temperatures;
  • costly.

On the contrary, the chemical nutrients are laboratory created. As a rule, the nitrogen produced by Haber-Bosch. Potassium and phosphate come from minerals. Together they form a defined NPK formula.
The benefits of chemical fertilizer are:

  • the strict formula gets the target;
  • fast result;
  • widespread usage;
  • affordability.

Despite the effectiveness of the chemicals, such plant food may ruin the soil and make it unusable for the next season. Alongside exhaustion of the ground there are such disadvantages:

  • can burn the plant if you overfeed it;
  • not friendly to the environment.

If you ask me, the best bloom booster for cannabis should be chosen with consideration of the soil composition, amount of light, humidity measures, sort of the plant, and all other external factors. Before choosing the plant food, try to predict how much time you will spend on fertilizing and what results you want to achieve. It will help you to make the right decision.
