18 hrs a day is fine and 3-4 feet is fine until you see signs that they've established themselves.The new clones should be on 18 hours of light a day right? How much water should they be getting, how many times a day? What temp should i be aiming to keep the room at? what temp should i be want the res water to be? How far should the clones be from the 1000w light? i was thinking like 3-4 feet?
Nutrient strength? It's RATIOS of each! DO you own a EC/PPM/PH meter? If so, concern yourself with EC/PPM and NOT 25% strength, 50% strength and so on UNLESS the directions say " If you follow these guidelines and mix at our recommended levels you'll end up with Blah, Blah EC/PPM.So just follow the recipe on the bottle but at 25% strength until i see new growth? then move up to 50% and slowly up to 100%?
What do you mean by well ph'd water? like 6.0? and what is H202? sorry if those are dumb questions...
