I've got more control over my humidity to try and solve my cloning issues and want your advice. I've been lucky if half of my cuttings make it. Read a lot of suggestions and often see people saying to take the humidity dome off after only 1-3 days. I took my dome off this time and they're in about 60% humidity but a few of them are showing problems bending over at the top like their heading to death's door, lol, you know what I mean?
Some more info. Cuttings were semi hard woody lowers off reveg's, I know that increases difficulty. I cut em, razor scraped and dipped in clonex and root powder. Put them in seedling tray dome with Riot plugs. Added tap and put dome on for 6 days. Was too hot first 6 day so I switched lights to one 20W led bulb 10" above, and makeshift covered with a white pillow case between light and cuttings to dull the light but allow airflow. Temps 79F, rH 63%. Changed water after 6 days.
My primary question is- has anyone determined the perfect rH for rooting? I haven't seen that % posted anywhere. Should I go higher? In prior attempts I've seen the 100% humidity result in mold/damping and dying, but I've actually had more luck leaving the dome on with vents closed at 98 - 100%, as long as they don't get mold. It never takes mine less than 3 weeks this way. I've also lost some that had good roots after transitioning to soil. So again, isn't there any evidence on the best rH% for rooting?
