600 Watt mh light 24/7 ???

Tis us again. We were wondering if our clones would grow faster under 600 watt mh light on 24 hours? Right now they are on 18/6 and are doing good, but we'd like to get them going a little faster if possible.

You get the best results with an even climate. It requires some experience to create the optimum conditions. The hemp cuttings form their roots best at a temperature of 25 to 26 degrees Celsius, and a relative air humidity of 70-75%.

I'm sorry. I wasn't very explanitory in my question. Our clones are several weeks old now and our biggest is a Big Wreck that is 10 inches and the others are about 5 inches. The others aren't going very fast and we're wondering if we put the 600 watt mh on 24/7 rather than the 18/6 it is now, if that would help them grow any faster? Also, what temp should the room be? It gets kind of cold at night. Thank you

the temp should be roughly around 80 degrees and it will not make your plant grow any faster putting it on 247 rather than 18/6 because im not definate but i think plants cannot take in any more than 18 hours of light a day anyway so would just be a waste of electricity. although if you have the money to waste it wont do the plant any harm havin it on 247. happy growing!

they will grow faster under 24 hours....thats 6 more hours of light, however i find that if everything else is right in your garden....mainly ph and nutes then the plants grow fast as all hell and you can save a ton on power by only doing 18/6 but then again if its shear speed your looking for go with 24
