    Uniform work protocol (recommended)<\/h2>\n
      \n
    1. Wetting:<\/strong> saturate the blocks evenly with tap water. Drain excess water.<\/li>\n
    2. pH & EC (pro-tip):<\/strong> optional water pH 5.5-6.0<\/strong>; built-in light EC usually eliminates the need for supplemental fertilization in Week 1<\/strong>.<\/li>\n
    3. Place:<\/strong> stab or sow in the 38 mm planting hole. Keep temperature\/VP-D and light intensity appropriate to the crop.<\/li>\n
    4. Manage moisture\/oxygen:<\/strong> keep blocks moist, but avoid persistent saturation; this keeps pores of air available for roots.<\/li>\n
    5. Scale up:<\/strong> transplant as soon as roots are visible – to larger blocks, pots or the final substrate\/cultivation system.<\/li>\n<\/ol>\n<\/section>\n
      \n

      Quality & performance<\/h2>\n
        \n
      • Better rooting:<\/strong> fine, branched roots colonize the block quickly.<\/li>\n
      • Stable microclimate:<\/strong> fiber matrix retains water while ventilating for strong starter growth.<\/li>\n
      • Safe and comfortable:<\/strong> pleasant to handle, no skin irritation<\/em> with normal use.<\/li>\n<\/ul>\n<\/section>\n
