The adjustable vent allows you to manage humidity levels during the rooting phase and gradually introduce ambient airflow as cuttings establish, reducing transplant shock and improving strike rates compared to uncontrolled propagation environments.\u003c\/p\u003e\n\n\u003ch3\u003eHow Humidity Affects Cutting Success Rates\u003c\/h3\u003e\n\n\u003cp\u003eUnrooted cuttings cannot draw water through their stems  -  they have no root system yet. They lose moisture through their leaves at the same rate as a rooted plant, which means without high ambient humidity around the foliage, the cutting wilts and dies before roots form. A humidity dome maintains relative humidity above 85 to 95 percent around the cutting, drastically reducing transpiration and keeping the cutting turgid while roots develop over the following 7 to 14 days.\u003c\/p\u003e\n\n\u003cp\u003eThe adjustable vent on the Large Humidity Crib allows gradual humidity reduction in the final days before transplant, acclimatising cuttings to lower ambient humidity before they are moved into the main grow space. This step is often skipped with simple dome lids that have no vent control, leading to wilting when cuttings are exposed to grow room conditions directly.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Works With\u003c\/h3\u003e\n\n\u003cp\u003eThe Large Humidity Crib is sized to fit the \u003ca href=\"\/products\/nef-tub-solid-23l-black-hydroponic\"\u003eNEF Solid 23L\u003c\/a\u003e and \u003ca href=\"\/products\/nef-tub-solid-45l-black-hydroponic\"\u003eNEF Solid 45L\u003c\/a\u003e tubs. Fill the tub base with your preferred propagation medium  -  rockwool cubes, rapid rooters, or jiffy plugs  -  insert your cuttings, and place the Humidity Crib over the top. For the most effective setup, use a low-wattage propagation light above the dome and a heat mat below the tub to maintain a 22 to 26 degree Celsius root zone temperature.

When the grated insert is sitting inside the solid tub, the dome still fits over the top of the assembly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it work with Clonex or similar rooting gels?\u003c\/strong\u003e Yes. The Humidity Crib is compatible with any propagation method  -  Clonex rooting gel, IBA powder, or plain stem cuttings in a moist medium. The dome creates the humid environment; your choice of rooting hormone is separate.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between the Large Humidity Crib and a standard propagation dome?\u003c\/strong\u003e Standard propagation domes sit on flat trays and are sized for seedling trays. The Large Humidity Crib is sized for NEF tubs, giving you a larger propagation volume in a format that works with the existing NEF tub system. The adjustable vent also provides more control than many basic domes.\u003c\/p\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e NEF 23L and 45L solid tubs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e Adjustable vent for humidity control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Cuttings, clones, seedling propagation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible tubs:\u003c\/strong\u003e NEF Tub Solid 23L Black, NEF Tub Solid 45L Black\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NEF","offers":[{"title":"Default Title","offer_id":43331771760703,"sku":"TNEFLHC","price":29.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/6898\/8479\/files\/large-propagator-lid_soft_Hyalite_hydroponics.jpg?v=1780399305","url":"https:\/\/apexgrow.com.au\/products\/large-humidity-crib-propagation-dome-hydroponic","provider":"Apex Grow","version":"1.0","type":"link"}
