Help newbie with question about clonning!!

Hey evry1 i have just potted (in clay pebbles) some clones that are about 4inches tall with good roots i have them hydro feeding and with light 24hr days. Just wondering wat the ideal water ph, temp and how long i should keep them like this before i change light times 2 18h on 6 off?.....basically i am worried i am gonna ruin my clones wich come from a friend with very good plants. any info would b great. thankyou.

for a hydro PH between 5.5-5.9 is perfect temp between 75-85f lights on and 75-78f lights off is good


when you feel like they got a good root system and there growing a bit slowly switch the lighting 24h then 23h on 1h off etc slowly till you get to 18-6


ive never grown hydro im on my first grow with soil but ive read alot about hydro systems all so

before you take my advice wait for someone with a hydro system to come in here give you some really solid advice

thanks uk cobra u obviousley no more than i do about it so hydroponics so any info is a great help thankyou.....1 more thing if u dont mind me picking your brains with a hydro kit i keep it running 24/7 dont i as the water drains away n pumps back in and the plants take wat they want as i flows through or will i b overfeeding them water?
