you dont have to ph the water if you buy good water. and i would buy a small hps from home depot lowes or Ebay. 75-150 watts will do you good if you are just trying to get your feet wet and not drown. if you have questions just ask. im always down to help out.
natural water doesnt come from your tap, unless you have well water or catch rain you dont have natural water.
dude, do you really think the water out of the tap is natural? cant you taste the chlorine and fluoride and all the other shit the treat it with so that it doesn't poison people? dont you notice the difference in taste in tap water and bottled water? if you dont have a ph around 7 for a soil grow the plants will not grow properly... that is one of the first steps in getting a hermie plant, you want to keep the plant stress free. plus if the ph goes too high or too low you run the chance of just killing your plants. atleast let the water sit so the chemicals will evaporate, p.h. your water to the proper level and add a couple of lights and see what happens... if there is no change in a week or so... i don't mean to sound too harsh but come on... there are a crap load of how to's on this site and one of the first things they tell u is PH your water they say that for a reason
security light, i always buy lights for growing but my buddy uses the security lights on the outside of his grow and they work really well. this will only cover 1-2 medium sized plants
keep looking i was there and at home depot like 2 weeks ago and looked at them, forget what they sold for though. they have them. it would be better honestly to buy a 150 hps from a grow shop on ebay. it will work out the best for you.
yeah man that light from home depot is a piece! i wouldnt pay $10 for that! it would be idea if you could send it to like your best friend/ brother sisters house that doesnt grow.
It is not a scam and everyone that has bought one has been completely happy with it. All you need is a cord as you mentioned and it will plug into any 120 volt outlet in the house. I'll post pictures below, that should help with any other questions you have.
