![]() If you’re using a DWC cloner and achieve extensive callous growth, change the water to mineral nutrient alone and eliminate the hormone product. Over-callousing would indicate the need to lower hormone dosage for that particular strain. Then set your cycle time to that which achieves the ideal temperatures. If you achieve extensive callusing, but roots lag, cycle your pump 15 min ON/45-60 min OFF for 24 – 48 hours or until 2 – 3 mm of roots form. We suggest 75 ☏ – 85 ☏ (24 - 29 ☌)Ĭallus or Callous is non-specific plant tissue that can become many different cell types depending on environmental factors or plant growth regulators. Through extensive testing we have found faster rooting at warmer temperatures with diminishing returns above 87 ☏ (30 ☌). ![]() Do not use hormones without mineral nutrients, the results are NOT the same.Ĭycle timing is primarily used for temperature management. It is important you include a mineral nutrient in concert with hormone products for maximum performance. We have worked mostly with Hormex Liquid Concentrate at 3 – 6 mL/gal. We have found efficiency in water soluble hormones such as Hormex Liquid Concentrate, Rhizopon AA, and KLN Rooting Concentrate. Each ensure adequate exposure times and eliminate the workload. Gels and powders wash off and are time-consuming to apply. We suspect there may be a bacteria or fungi for aeroponics, but have yet to demonstrate strains of interest for long-term effectiveness.Īuxins improve rooting time and root volume. Avoid products which will inoculate or feed bacteria and fungi such as amino acids, protein hydrolysates, sugars, carbohydrates, or ‘teas’. We recommend nutrients intended for water culture. We currently recommend 4 – 8 bulb T5 fixtures 4” from the canopy with mixed blue and red spectrum bulbs.Īdding 1/4 -1/2 strength bloom nutrients (200–600 ppm or EC: 0.4–1.2) to the cloner improves rooting both in speed and volume. This is particularly important when taking multiple clones per collar. We ramped up lighting to 4 bulb T5 flourescent fixtures at 4” from our cloners’ canopies and achieved significant improvements in cloning rates, speed, AND root mass. Over time we noticed shaded clones rooted slowest or failed. This is not the case with hydroponics cloning. This was because plugs couldn't hydrate the cuts enough to prevent wilting. People often place a single T5 1 – 2 feet above the cloner canopy. The common suggestion has been minimal lighting. Leaves will help generate the carbohydrates needed for prolific rooting. Below we discuss how to maintain mother plants for effective cloning. We recommend trimming leaves to avoid shading other clones OR if your source plants are over-fed nutrients with dark green leaves. You may remove the fan leaves to avoid shading other clones but this is not necessary with aeroponics, DWC or bubbleponic cloning.Ĭutting fan leaves has traditionally been intended to decrease transpiration, but that’s not a concern in aeroponics. The more nodes left untrimmed from your cutting, the more endogenous (natural) auxins will be produced and sent to the basal (bottom) end of cuttings. Alternatively, if your ambient temperature is 75 ☏ and your cloner is at 77 ☏, your IR reading will be relatively precise.Įvery shoot apex produces auxins (rooting hormones). For example, if your ambient temperature is 75 ☏ and your cloner is at 85 ☏ (29 ☌), you IR reading may be 83 ☏ (28 ☌). We have found external IR readings to be within 0 – 2 degrees below the actual internal temperature and this range depends on the ambient room temperature. This is fast while preventing contamination of your cloner. Use an IR Thermometer or permanently placed temperature meter to quickly measure water temperatures. ![]() We believe this temperature recommendation may increase as techniques improve for effective water treatment. With DWC the goal is the best temps for both oxygenation AND root growth. Before attempting higher temps, get sterile! Deep Water Culture (DWC) is different than aeroponics. However, this also speeds growth of bacteria and fungi. In cloning, warmer temperature speed cell divisions with diminishing returns at 87 ☏ (30 ☌). As always, I keep efficiency and scaled production in mind! This article is about those methods that produce clones covered with roots from collars to cut.and with no loss of growth potential or yellowing above the collars. This article is about methods for producing the unbelievable clones you see PermaClone customers rep'ing on Social Media! In my article the The 3 Main Reasons Cloners Fail I cover those issues that cause cloning failure and help you gain predictable results.
