yea keep it simple .. and try to think logic .. its a plant .. weed .. you want to grow it inside .. what you need to do is to try to copy nature ..
it will need sun/light .. rain/water ... winds/fans .. and food/nutriens ..
you WILL also need a way to keep light out at night time (and I mean all lights) and also a way to keep odour in .. since they will stink .. realy bad ..
.. so a air/light seald room . with a ventilation and activ carbon filter is a must ..
then you can grow with no smell .. keep tempertures down and provide fresh air/co2 for your girls ..
about light .. many ways to go .. dont know anything about LED since they are new and costly .. and dont seems to be doing so great yet ..
guess they need more research ..
I use T5HO for Veg and a 600W HPS for flowering (more or less standard I belive)
about your "friends" light .. a bit expensiv I would say .. at fist glance ..
try to have a look at this site:
http://www.greners.com/i/grow-lights...-fixtures.html
dunno just found it randomly .. but even seems to have a sale ..
atlest show your "friend" it so you might be able to get his for less
but realy its a jungle out ther .. and ther are many ways to do this .. it also depense on your set up/space .. your $/wallet and how much effort you want to put in to this and what you expect ? and if you etc. go with a big MH/HPS you will also need a big ventilation aso ...
do some research .. but a nice set of fluorescent light is a good way to start out .. atlest for Veg. can do some more research/shopping wile they grow big under some nice T5HO lights .. I would strongly suggest you to go with T5HO (HO=high output) if you buy fluorescent and some of the right bulbs (6500K/2700K) stupid so safe pocket money and end up with sumthing that just dont do it for you ..
if 4 plants at the time is a goal for you (a lot of Ppl. who grow for them self do 2-8 .. I belive 4 is quite normal .. fit under a 4 foot T5HO lighting/HPS .. need 6-8 bulb fixtures if you want to go all the way .. 2 bulb can handle seedlings .. I have a 6 bulb and I use it for 4-6 weeks doing Veg .. then I veg a week with my HPS wile I go down in light time from 20 to 12 .. cut a hrs a day or so ..
agin .. many ways to do it .. if you have the money and space ..and maybe a AC if your live in a hot place ?
a nice tent with a 400/600W MH/HPS cool tube and a nice big ventilation/filter would be great Im sure ..
