DWC and coco.. i know in dwc to keep the RR well above the waterline so it doens't cause stalk rot.. at least from what i read.
P.S. thanks guys
These "hydro" (no medium) style cloners are great for transition into r/dwc (obviously
) and coco. With coco you fill the pot/solo cup some, then hold the root mass at the top of the coco, and fill/dump in around it, basically.
And yea, definitely leave a space between the plug (if any, if not, then the stem) and the waterline, even between the plug/stem and the bottom of the netpot lid. The roots above water generally are/become "air roots".
BTW... and sorry diggs, not trying to hijack. but since we are all here
One thing i dont' get about aero is i see guys running like 30min on/off or other long times.. wouldn't like 1 min on 15 off do the same thing? inside the bucket is like 99% humidity and i doubt roots would get near dry even in 3 hours let alone 15 mins.. why the long spray time?
I think it's really about temps (or energy usage if that would be a concern to someone). If running pump 24/7 doesn't cause temps to get too high, you'd probably never think twice about anything. I think the intervals became a method for controlling the temps of the water/tote/etc. Different durations of on/off will result in different max temps, and once you got it dialed in (consistent temp with little variation of heating and cooling) that's probably the on/off interval you'd stay at.
Just my thoughts on it.
I've even
heard that the water droplets running down the cuttings stems stimulate root growth but I haven't read anything scientific in that regard. Interesting that's all.
edit: Maybe an "ideal" level of moisture on the actual stem is beneficial to "drawing out" the roots, and so having an off time dialed in to dry them out
just enough helps with that. Not sure, just thinking out loud.
