How long on average does it take to get roots in a decent bubble cloner?
I have 2 built and running at the moment
- 4.7 gals tap water(water is ph8.2 and 100ppm .7conv from tap)
- plenty of air, 2x 12" airstones in each cloner with its own 400 litre per hour pump, loads of bubbles
- 2 drops superthrive
- few drops ph down (phosphorus based) to bring ph to about 5.8-6.3
- aquarium heaters in each keeping water @ 73-75F
- air temps @ 73-75F, humidity@ 50-65%
- tips of stem are submerged about 1/2 inch and I let it drop to about 1/2inch below them so bubbles are popping and keeping stem wet at all times
- cloner was light proof afaik, i spent hours making sure it was by filling any pinhole light leaks.
- cloner and all equipment were cleaned with light bleach and rinsed a lot before use, so it was clean and the blade i used for taking clones was cleaned with iso-alcohol also.
- I only top up the cloner with plain water and ph to required level
When I took the clones and cut from mother plant with a very sharp blade (did the angled cut for more surface area), i scraped the top layer at the bottom of stem (as many guides state to do), dipped in rooting gel and straight into cloner. about 10% of them drooped for a few hours and then were fine.
I have cloned the strain before in root riot cubes in a propagator and they roots started showing in about 9days (same mother plant as current batch). But it has been 4 days now and no sign of rooting at all (i know its early days though). Leaves are perky/ no yellowing/ no drooping
However I tried before in a bubble cloner with the same strain and within 2 weeks there were no roots and only about 40% of plants had the lumps on the stem where roots form (i didnt have an aquarium heater at the time and water temps were real low, so i put it down to that). Some people say they get roots in like 4-6 days, some say up to 3 weeks. why do mine seem to take ages (or not happen at all)? What are some other factors that can affect it? The clones seem to stay healthy and no sign of mold/blackening/air embolisms etc, its as if the clones are thriving but without roots. Anyone any suggestions (+rep given)?
