Clone Dome R.H.?

I've been having some problems with my last couple batches of clones. I'm not gettin as many to root as I'd like too or what I was getting last summer. I think my main problem is the humidity as its only 35%. I have a 72 plug dome & I was using a reg heating pad but it would shut off at a certain temp so I got a heat mat from the hydro store & its not gettin as warm. I'm misting the plants & dome walls 2 times a day. Is there a way to increase the humidity in the dome? Thanx.

With the dome on your humidity inside the dome should be very near 100% unless you have cut vent holes or it has vents open. Personally, I don't like to use the dome more than 24 hours, as I tend to lose clones if I leave the dome on too long. 24 hours, then I remove it and mist them several times a day, I get 100% success.

Thanx for the reply but that doesn't really help me. I know the humidity is supposed to be 90%-100% and the dome is on 24 hours a day except for the 2 times I take it off to mist. Do u have any ideas to increase the humidity? Thanx.

Buy a new humidty meter . In a closed off dome on a heat pad misting twice a day it should be 80 + Rh in there
.A trick for your heat pad that shuts off . Put it on a 15/15 timer on for 30 off for 15 works great . Are you filling your tray with some water? It should form water vapor on the dome from the heat pad alone .

Thanx alot King. I didn't even think about using a timer. I know my temp/RH meter works cuz I use it in my grow room. I didn't measure the RH when I used the reg heating pad but there was a lot of condensation on the dome from the humidity. It was staying on for about 2 - 2.5 hours before shutting off which sux when im sleepin or at work. Thanx again for the input, I appreciate it.

If there's condensation inside the dome, but your hygrometer is still reading in the 30's, something isn't right, common sense should tell you that.

condensation cant happen without 90-100% humidity...your meter doesnt work.

He did say he didn't check it with the heat pad that formed the condensation .

That's true, I didn't see that.

Waaaazzzzzup rick! Go back to ur old heating pad&use a timer. Justa thought?
