Twan Bouten: “We have been using BVB TopClean for two years now. Using this covering agent realy saves us money. It also saves us a lot of extra work, because it prevents spilling the substrate when we move the pots. This way our tray fields, carts and trucks stay clean. It's great not to have to worry about weeds (mainly willow). With BVB TopClean on the pots we hardly have any problems with that anymore.” Picture: Rick Tissen, crop manager

Instructions for use

  1. Apply a layer of BVB TopClean of at least 1.5 cm to each pot.
  2. The top layer will become one solid layer after a number of times watering the plants. As a result, no material is spilled and the tray field and means of transport remain clean.
  3. BVB TopClean can easily be applied with any common dosing machine.
  4. The covering agent occupies approximately 10% of the pot volume. For that reason, a possible adjustment of the amount of fertilizer must be taken into account.
  5. The use of BVB TopClean reduces the evaporation in the substrate. Keep this in mind when setting the irrigation frequency.
