The Pre-Planting procedure is essential in order to prevent problems and difficulties during the growing period.

  1. First Stage – While placing Pelemix’s growbags on top of the gutter, it is important to make sure that the side of the logo is the upper side.
  2. Second Stage – Make sure that the pressed material is in the middle of the plastic bag and that the plastic edges are pointed upward.

The distance between growbags should be according to the planting program. In any case the distance between two pressed slabs should be no less then 2 cm (about two fingers).

3. Third Stage

Every 20 cm (or less) there should be individual arrow dripper. The recommended flow rate is 1 Liter/hour or less. When the coir is pressed it is impossible to tack the arrow dripper, therefore it is important to insert all of it into the plastic bag

The holes in the plastic can be done with a sharp object like a screwdriver.

4. Forth Stage

The quantity of water that is needed for a growbag to expand is about 70% of its final volume. For example, the quantity needed to expand 18 liters growbag (100x15x12) is about 12 liters.

5. Fifth Stage

During the expansion, it is very important to apply a calcium nitrate treatment. To every expanded cubic meter [1000 liters] of coir, 3 kg of calcium nitrate must be applied.

For example: 55 growbags of 18 liters each comprise a cubic meter of expanded coir. The easiest way to apply the calcium nitrate is with the water

used for expansion. For example the quantities for 55 growbags of 18 liters are: 660 liters of water and 3 kg of calcium nitrate.

It is recommended to apply this treatment in a few irrigation cycles. After the full treatment (after completion of the few irrigation cycles) is given the material should be suspended for 48 hours.

6. Sixth Stage

After 48 hours, drainage holes must be made. The holes must be made on both sides of the growbag, on the corner between the side and the bottom of the grow bag (On the edge of the growbag). Each hole must be 6-8 cm long. In total there should be at least four draining holes.

7. Seventh Stage

The growbags must be washed by clean tap water. The washing will reduce the E.C. level of the drainage water to the level of the tap water. This procedure may take time and water, but is crucial for the growth of the plant.

8. Eight Stage

During or after washing, planting holes should be made and the arrow drippers should be reinserted into the growbag.

9. Ninth Stage

After washing is finished, the growbags must be irrigated for 4 days with a complete Fertigation formula.

When the 9 stages are successfully completed the growbag is ready for planting.
