Well one thing for sure, it will not be hermie because they are clones, I think, if by hermies u mean males. I've grown them for about a month in vegetation mode and they're about 1 foot tall. So I've switched to flowering mode (12/12 light cycle) at exactly one month into veggie and so far they're looking ok. How much yield can I expect from each plant if they're grown under 400W MH light? Oh and all this was done without a PH meter, maybe next crop I will get one since you all agree it's extremely important. Sorry I am still a newbie and this is my first grow so any advice is appreciated! Thanks all for your inputs!

Just in case, my setup is as follows:
2x400W MH using one ballast (works like a charm =p)
Exhaust fan only
20-20-20 Nutes using at 1/3 strenght (no nutes for flowering as of yet, can I continue with this nute throughout the plant's life cycle?)
All this in a 3x2x8ft closet which is double stacked. 4ft for each compartment=1 light per compartment.
tekneeqs Reviewed by tekneeqs on . Is PH checker really necessary? Just a simple question. Can I still grow a good crop without a PH meter even if my PH is not optimal? I guess what I'm really wondering is, would the PH level alone render a crop cropless? Or can I still grow but just not the bomb shit? Thanks! Rating: 5
