is furnace making too dry?

i have clones like about 10 ft away from my furnace in rapid rooters.. they are in a humidome under a heatpad under a floro light.. its been about 12 days they havent rooted yet.. they were put in rooting gel and cut properly.. aside from the clones i have another ebb system that is on week1 clone/seedling gh nute schedule.. it feeds 4 times a day and once at night and that is under 5 t5 floro bulbs.. right now there are clones in there that started rooting from about 2 weeks ago and the roots are growing but the plants look like they are dead still lik eyellow leaves and dry .. the middle of them looks fresh though and alive.. like the smallest part of the top of the plant.. its just the leaves around it look dead still and the clones dont seem to be growing its been about a week in that system.. i was wondering if the furnace was causing both of these problems and i was also wondering if the systems i am using are right? my plan is to have teh clones root under the small floro in a humidome then put them in a week1 nute mix under t5 floro's that are about 6" above the tops.. after they are growing on week one im goin to either put them into blooming after about a week or put them back into veg.. is this gona work? what is the problem why the clones from teh last batch arent growing and the new ones dont seem to be rooting.. ive been kepin them moist and letting them get fresh air twice a day.. and the ones in the ebb and flow are just out and the roots seem to be growing but the plant isnt.. what do u think?

Well, what is your RH? Tuff to say its too low if you dont tell us what it is. You dont have a RH gauge ?

One sign you have low RH is if you walk across the carpet and get the piss shocked out of you when you touch something metal.

If your furnace is an older forced air without built in humidifier, I bet its drier than a popcorn fart in your house. Do you need an ice pick to dig stuff outa your nose in the mornings? Thats another sign you are drier than dust.

yeah all that stuff you said has been happening to me so i think its just too dry.. i moved the clones to a room out of the enviromnemt but the only problem with that is that they will have to adjust when i move them back after they have rooted..

just use a humidity dome.... and when they root u can revert them back to normal room humidity but simply opening it up a couple times a day.

def use a dome,or to increase your humidity you could put a bowl of water in the room with a fan blowing on it. Humidity sensor is like $6 at walmart.
