Barrier by Top Crop is an additive used alongside your growth and flowering nutrients. Increase your plants’ strength by increasing chlorophyll content, which in turn improves the photosynthetic process and makes for more rigid trunks and branches that will easily be able to hold up hefty buds.

This product is 100% dissolvable in water and compatible with all kinds of automatic watering systems. It can be used in any growing medium to keep your plants healthy and strong.

You can apply it via spraying, diluting the mix and spraying your plants’ leaves along the top and the bottom in order to get an almost immediate effect. Insect infestations will find it much harder to get past your plants’ new protective cell wall. Outdoors it’ll cause unwanted pests to move on to other plants.

It increases the thickness of your plants’ cell walls, helping them to deal with hotter temperatures and insect infestations. Get stronger, healthier plants that have an intensely efficient photosynthetic process, which helps nutrient transportation. It also increases the amount of CO2 that your plants can absorb. Grow stronger, more robust plants with a thick skin that can withstand almost anything!

Dosage and how to use Barrier by Top Crop:

  • 0.5ml per liter of water.
  • You can use it during the growth period and at the start of the flowering period to reinforce your plant. Use it again a month into flowering, when they start thickening up.


  • Potassium silicate
  • 3.92% potassium
  • 7.8% silicon
