Tetra 9 from Agrobeta is a very complete organic supplement, which contains macronutrients, micronutrients, amino acids, humic acids, fulvic acids, vitamins, carbohydrates, and other compounds that promote, facilitate, and stimulate the process involved in the change to the flowering phase for marijuana plants.

How is Agrobeta's Tetra 9 used in cannabis cultivation?

It only takes 3 applications of this product to take advantage of its benefits, so its quality / price ratio is very interesting. In indoor cultivation, the first application must be given 10 days before changing the photoperiod to flowering, at a rate of 1.5 ml / l. The second time the dose must be increased to 3 ml / l and it is given on the same day as we change the light cycle to 12/12. And the third and last dose is repeated and must be done 10 days after the second.

In outdoor crops we cannot control the photoperiod, so we have to rely on the signs that are perceived in the plants when they are changing phase. Outdoors, the growing cycle is lengthened compared to indoors, so we can space the margin between each application more than 10 days. Indica varieties start to flower before sativas, so you cannot set a specific date to give the first application of Tetra 9. But don't worry, it can be done as follows:

Once it enters officially summer in your country, pay attention because the fastest strains will soon begin to stretch their structure, widening the distance between nodes to place the buds there. At that time you can give the first one with a dose of 1.5 ml for each liter of water. The moment you see the first pre-flowers begin to appear, you can give the second application, this time at a rate of 3 ml / l , and 10 or 15 days after the second, the third must be given, also at 3 ml / l.
