T-5 fluorescent tubes are fading away and being replaced by LED fixtures.<\/p>\n\n\n\n
Lighting: <\/strong>Clones need low levels of light to survive while they are striking roots. Fluorescent lamps, low levels of CFL, LED lighting and ambient or highly filtered sunlight are all clones need to carry on life processes until they grow a strong root system. Once they have developed a strong root system, clones can utilize more intense light. After transplant shock has passed, clones can process light necessary for vegetative growth.<\/p>\n\n\n\nSet light timer <\/strong>to 18-hour days and 6-hour nights<\/p>\n\n\n\nTemperature: <\/strong>Clones root best in a temperature range from 68-78\u00baF (20-25.5\u00baC). Warmer air temperatures may not speed rooting. Keep temperatures at the ideal 75\u00baF (24\u00baC) for best results. As with seedlings, increasing bottom heat 2-3\u00baF (1-1.5\u00baC) speeds root growth.<\/p>\n\n\n\nHumidity: <\/strong>High humidity (85-95%) is necessary for the first couple of days after cutting and sticking clones. Place clones in a humidity tent or humidity-controlled room. They can handle lower humidity (70-85%) after the first 3-4 days because they are more acclimated to the environment.<\/p>\n\n\n\nClones need a little air circulation and ventilation. Usually a humidity dome with at least two adjustable vents located on either side supplies enough natural airflow to be sufficient.<\/p>\n\n\n\n
Water: <\/strong>Give rooting clones distilled water or water with very low (<100 ppm) of dissolved solids and a pH between 6.0-7.0 for best results.<\/p>\n\n\n\nNutrients: <\/strong>Clones do not need any nutrients until after they are transplanted. Some growers start fertilizing with a very mild nutrient solution just before transplanting.<\/p>\n\n\n\nGrowing medium: <\/strong>Stick clones into Ellepots or Easyplugs or into preformed root cubes \u2013 Jiffy\u00ae, rockwool, etc. You can also use fine soil or soilless mix that holds a little more moisture and plenty of air. The substrate must have plenty of air for clones to grow a strong root system. Use cubes that have similar waterholding- ability as the growing medium clones will be transplanted into.<\/p>\n\n\n\n
