shit i just irrazed this message and now writing it again fuck .understand
about the reflector now
if the grow space is 6' x 4' get a 600 watt HPS and save your self 50 watts and
the labour of getting an even spread ( a 600 will sit nicely in that space ) ,if
you still want to get a 400 get a light mover that rotates so you can spin the
400 + the 250 and get an even spread .personally i would go for the 600
myself lest electricity and labour .... which is nice lol.
now i no and obviously you do that the normal grow lamps and ballasts that
are found in hydroponic shops are the same ones (nere enough) in the
electrical supplier shops, the only difference is the bulb
the bulb in hydro top set ups are normally "agro bulbs " that are just for
plant growth in fact there are about 5 to choose from in the electricity
suppliers the standard is normally the son-t basic bulb now the flowering
frequency is 2700 kelvin the basic son t is about 1900 buy there are bulbs in
between the 2, i found one that was 2500k and throught that it would surfice,
i asked a local hydroshop ,the guy i get on with about the kelvin range ,he
said that the basic hydroponic grow lights are 1900 kelvin , which is crap but
they grow plant fine ........ the thing i found out is this
its not about the kelvin its the .....light output,,,,,,,, so fuck the expensive
grow bulbs and buy cheap ones that are close to the kelvin of 2700 but it
doesnt need to be perfect!
stick with HPSs dont do flos unless your vegging
hope that answers your questions
peace
