Green OK Humic Concentrate For Cucumbers | 750ml (MOQ:3) is a targeted solution for gardeners who are serious about achieving a premium cucumber harvest. It's not a replacement for base fertilization (like NPK or compost) but a powerful biostimulant that makes your existing fertilizer and soil work much more effectively. The MOQ of 3 makes it ideal for gardeners with multiple plants or those who plan to use it consistently throughout the season.
