The steps to do it correctly are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cut the rockwool<\/strong> using 3.8 cm blocks for small cuttings and 10 cm blocks for larger plants.<\/li>\n\n\n\n<li><strong>Moisten<\/strong> the rockwool blocks with water at a good pH (ideally between 5.5 and 6.0) to ensure they are completely damp.<\/li>\n\n\n\n<li><strong>Prepare the cuttings<\/strong> by cutting just below the node, always ensuring that the tools have been sterilized before use.<\/li>\n\n\n\n<li><strong>Use rooting hormones<\/strong> by dipping the cut tip of the cutting into the rooting hormone.<\/li>\n\n\n\n<li><strong>Place each cutting<\/strong> into the rockwool blocks and into a tray, ensuring it is firm but not too compacted. It can be placed in a propagator to maintain high humidity.<\/li>\n\n\n\n<li><strong>Maintain a good temperature<\/strong> and proper ventilation during rooting. For this, the temperature should be around 27 \u00b0C.<\/li>\n\n\n\n<li>When <strong>visible and strong roots are achieved<\/strong>, they should be transplanted to larger blocks or a quality hydroponic system.<\/li>\n<\/ul>\n\n\n\n<p>Maintaining proper hygiene is crucial throughout the process to avoid problems like algae or excessive lime buildup, which could alter the pH of the medium.<\/p>\n\n\n\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Most_common_problems_when_using_Jiffy_and_rockwool_trays\"><\/span><strong>Most common problems when using Jiffy and rockwool trays<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Although Jiffy and rockwool trays are <strong>effective methods for rooting cuttings<\/strong>, some common problems may arise during the process, such as the following:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Wetting_the_Jiffy_pellets_or_rockwool\"><\/span><strong>Wetting the Jiffy pellets or rockwool<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><strong>When<\/strong> you spray the cuttings directly over the medium, it can get too wet. You can <strong>cut the tray into double rows of 5 to get 15 pieces of 10 cuttings<\/strong>. Spraying the cuttings upside down before returning them to the propagator ensures the medium does not get wet, accelerating rooting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Excess_humidity\"><\/span><strong>Excess humidity<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><strong>Excess humidity<\/strong> in the medium can cause the stems to rot.

Algae usually grow in environments with high pH, and adjusting it can prevent their appearance.<\/p>\n\n\n\n<p>If you keep these tips on <strong>how to use Jiffy pellets and rockwool<\/strong> in mind, you can obtain quality results easily.<\/p>\n\n\n\n<p><\/p>\n<div style='text-align:center' class='yasr-auto-insert-visitor'><\/div>","protected":false},"excerpt":{"rendered":"<p>Are you wondering how to use Jiffy pellets and rockwool correctly?
