caddy i may had misunderstood the pulse/ignitor honestly. im not an electrician and never gave much thought to how a bulb actually starts up. i think where most people may get confused is that on mine my ballast actually must pulse as it does when firing up it, pulses 4 or 5 times and then the bulb ignites on my set up. but to be honest with you,my ballast is old school i guess, and the setup was originaly made for aquaria bulbs, whether that makes a difference.
I do also know that my does not pulse, when the ballast fires up, the light instanlty comes on and then fires up over a small period of time so in my i guess i had ingnitor and pulse backwards. thanks for clearing that up.
anyhow, i clone in a small closet seperately, but ive never used a hood for cloning. alot of people do and they say that high humidity levels are good as well. I have never had seen a need to. To be honest, i did try a dome once, my very first time and my very first batch was a total loss lol. i found the water and glass method for me was the most simple like i said.Cutting, water in glass, plcaced in indirect light for a couple few days and bam.
