Need some advice...

o'k got some very good soil, my plant is 4 week's old and i am wondering if it's a smart thing to change the soil?? if it is possible how would i go about changing it?? is it a good thing to have th root's naked for new soil??

well since it is doing good in the soil you are currently using why dont you just stick to that type? if your plant is 4 weeks old the best thing to do is to transplant to a bigger pot if you havent already done so! good luck dude!

Why would you change the soil? After a month or two...your plant has turned even the best soil into pretty lifeless crap. Just feed the plant nutrients now.

SAve your new soil for your next grow.

no don't change the soil, no need to.
