A Newbie needs your help!

I am a new to all this. I just assembled my grow room using a 400 watt setup. I am using a hydrophonics system with a bubbler system. I bought my seeds from BC Depot, I am using Sweet Dreams (feminized), yes i did recieve them within a week of ordering them, order 12 and recieve 15!!! I am using rockwool with distilled water, I have nutrients on the way, should be here in a day. I have never tried to grow before and any suggestions would be so grateful.

read read read books online and also lots on youtube vidoes.Some advice will be crap so before you try anything new find a couple of people who tried it and if they all have good things to say then try it.ventilation is critical along with temp and humidity.get a good min/max thermometer/hygrometer.the have them at hydro stores or wallmart.(get the kind with the sensor)good luck post pics and more people will help.

I have a remote temp/humidity meter installed. My ph level as of now is a 5.6. I have three starter seeds I am trying to germinate. I have added some pictures of the grow room I recently completed, I have extra holes already drilled in case I need more ventilation and one for my air filter purifier when it arrives.

this website is the best stick to it. Man to tell you the truth grow a little of everything get a feel with nature. pay attention to how god works

once my ladies come up ive read that my light should be 12" above the plants, would you agree?
