Tips & Tricks 1. Growing with high EC (1.8-3.5) is possible,but check Ec level in growing medium during periods with high temp.(Ec can increase to much because of more watergifts). 2. Start after potting with low EC (0.5) So roots can easily grow into the growing medium and Bild up to 1.5-1.8 EC.
3. If grown outside pay extra attention on EC level in growing medium.
