Our Top Crop products can be used for growing both indoors and outdoors, as the results are just as positive for your plants in either case.

We don't recommend using our line of products for hydroponic plants, except when the product expressly indicates the contrary.

Our line features both products that are 100% organic and the necessary organomineral fertilisers, which are nearly obligatory for strengthening flowering and improving both size and density of the buds. Meaning it contains some organomineral compounds that are essential to proper plant development.

To know if you're using the right fertilisers, first we have to understand chelation. Chelation is a state in which plants can properly assimilate iron, copper, zinc or magnesium.

We recommend starting to use Top Crop on the plant in the following situations:

You can download our growth chart here.

The NPK index shows the amount of Nitrogen (N), Phosphorus (P) and Potassium (K) in the fertilisers. Growth fertilisers are richer in nitrogen and have less phosphorus and potassium because plants mostly need nitrogen in the growth phase. Bloom fertilisers, however, are richer in phosphorus and potassium because plants consume more of these two elements when flowering.

You can use our fertilisers all in one watering, by mixing them, just follow the doses on the product labels. If you have any hesitations, however, you can also apply them separately without any problems.

Put your finger into the substrate and see if it is dry. If it is, then water. If it is still damp, wait a bit more. Too much water can kill your plants. You should also check the pH of the water you use. Water with your fertilisers once a week and start with lower than the recommended doses to see how the plants react.

You can get great results from your fruit and vegetable plants with our products and well-aerated soil, applied weekly and in progressively higher concentrations.

  • Before germinating, keep your seeds in an appropriate spot (cool and dry).
  • Don't over invest in what you need for growing, especially if you're a beginner.
  • Growing inside requires devices that allow plants to grow as if they were outdoors (lighting, artificial ventilation, etc.).
  • Get the right layout for your grow tools.
  • Don't put lights too close to your plants.
  • Avoid excess dampness with proper ventilation.
  • Don't trust urban legends, rumours or "tricks". Trust the experts.
  • Don't over-do it with fertilisers or boosters.
  • Make sure animals and pets don't get into your grow area.
  • Periodically review your plants and grow devices.
  • Keep your grow area clean.

  • Think about the number of hours of direct sunlight.
  • Don't over-do the fertiliser.
  • Use the right size pot.
  • Don't use black pots outside.
  • Don't put your pots on surfaces that get very hot.
  • Respect the cycles when watering and avoid the sunniest times of day.
  • Check and balance the pH of the water.
  • Avoid light contamination.
  • Don't be impatient about the harvest.
  • Flush the roots before harvesting and don't fertilise for the last week.
  • Don't stress the plant (for example, moving it around or putting it somewhere with too much contact).
  • Don't use water that is too cold.
  • Don't transplant while the plant is blooming.
  • Don't transplant with damp soil.

  • Too much or too little water.
  • Over-fertilising.
  • Under-fertilising.
  • Poor environment (remember: fresh air, temperature 25-30º, optimal watering)
  • Harvesting too early.
  • Indiscretion.

Yes, flushing the roots is the most important thing you have to do before harvesting to get buds without undesirable flavours or any problems that might come up when you consume them.

We know this information doesn't have much basis in science but we decided to include it for those who are curious and because, despite its lack of rigour, many growers still find it interesting.

  • Waxing: Favours growth of foliage and roots. If you plant a few days before this phase, your seeds will sprout faster and more homogeneously.
  • Full moon: Little root growth and a lot of foliage growth. Not a good time for cuttings. Plants transplanted during this phase grow quickly and produce a lot of foliage.
  • Waning: Fast, vigorous root growth. Slow foliage growth. Perfect for transplanting.
  • New moon: Slow growth of roots and foliage. Perfect for resting, trimming, fertilising or staking.

If the plants aren't lacking in these minerals, it isn't a good idea to add calcium and magnesium to raise the EC. By applying these two compounds effectively, you can calibrate it but with that small difference. In theory, no serious harm will be done to the plants but it isn't recommendable.

There's no risk in combining these products. If you have any hesitations, however, you can also apply them separately without any problems. Plus, you can lower the pH if you need to.

The most suitable pH for the soil your plants are in is between 6.3 and 6.5.

To achieve this, add Top Crop fertiliser to the water and check the pH. If necessary, adjust until you reach the right level. To adjust the levels, you can use cider vinegar or citric acid to lower acidity as a home remedy. And to raise the acidity, Barrier is very helpful.

Top Crop products should be stored at room temperature in a dry place (low humidity) away from direct sunlight.

It is IMPORTANT to close the bottle tightly.

Here are the recommended doses and days: 2 ml/L of water. Apply as a spray on the leaves and through irrigation 10 days before flowering. Continue applying twice more every 10 days. Given its alkaline nature, don't mix it with products that have an acidic pH level to avoid undesired reactions.

When you prepare the substrate, mix Micro Vita with Complete Mix or Heavy Mix for a super-concentrated cocktail of power and vitality for your growing.

You can also use it while your plants are developing if you see they have root issues by adding it to your normal watering, stirring well.

Micro Vita can be used in two ways: Mixed into the substrate directly or in watering.

Mixed in soil: 2-5 grams per 10 litres of soil.

Watering: 2- grams per 10 litres of water.

When the roots are already coming out of the jiffy pots, you can use Micro Vita in the substrate to help the cuttings boost their rooting power.

To make sure the dosage is right while you're watering you have to stir constantly.

It helps you get the most from your plants, boosting the number of shoots and promoting flowering.

It isn't a problem as long as it wasn't in direct sunlight. However, it is important to follow the storage instructions to ensure the product retains all its properties.

You can use Barrier any week for auto-flowering plants, in the growth or flowering phase.

To add it through irrigation: 0.5 ml/L of water and pour around the roots. Treat once a week.

As a leaf spray: Dilute in warm water 0.25 ml/L. Spray on the leaves at the end of the light cycle. Repeat once a week to prevent pests.

After the first 14 days, for one week. Afterwards, during flowering, you can use it from six weeks.

Yes, you can use these until the end of flowering but we recommend not going overboard with preventative measures.

Dilute it to 1-2 ml / 1.5 L of water and use the mixture to water once a week. Plus, you can use Deeper Underground throughout the grow process for better absorption and stronger roots.

Yes, as it contains molasses, Top Candy has quite a strong odour.

We recommend using our products once a week and you can combine Top Bloom with other products. We also recommend watering with plain water, not just the waterings with fertiliser. For auto-flowering plants, pay attention to the weeks as a good indicator.

Both are used in the substrate, but in different phases. Nitroguano should be used in the growth phase, as it has extra nitrogen, and Superguano during flowering, as it is higher in phosphates.

First use Nitroguano and one week before the flowering phase begins you should switch to Superguano. If you go the organic route, we recommend you avoid organomineral fertilisation. If you choose to add other Top Crop fertilisers, however, you shouldn't have any problems as long as you adjust to the lowest recommended doses and respect the recommended frequency.

Big One is a flowering booster from plant extracts that helps you get bigger flowers and, therefore, more resins and essential oils. With Top Candy, you get greater weight and volume of flowers, but also notably better smell and flavour in your harvest.
