I plan on having a 16 plant sea of green in a 4X4 (one plant per square foot), using some kind of hydro (flood and drain) in some kind of medium.
Now my question is, even though all the books say 400 watt HPS is OK for a 4X4, will it be enough for 16 plants?
Would it be OK to suppliment it with some CFLS or do you think it's neccessary I get a 600w?
id go with the 600 only because for the extra 200watts it puts out almost twice the lumens as the 400
if you are really going to do SOG then reduce the size of pot to 15 cm or 6 inches 3.5 liters each,
The lamp is fine for 1 square meter in sog ,,you have 1.5 meters square, with only 16 plants, i imagine you want to grow your crop a little bigger than in sog, there fore the penetration of a 600 watter would be much better,,
the 600 hps unit , is the most efficient of all the lamps when comparing lumens to power output!there for always better a 600 than a 400.
whowever i have two meters square that share three 400 lamps and another two square meters under one 600 each, although it is cheaper to run two 600's the three four hundreds give a better light dispersal over that area. of course the more light you have the better!, unfortunately this cost has to balance with the value of the crop! and the electricity bills have to be,,,,,,"reasonable" so as not to attract too much attention from the electricity supplier!.
by maintaining the crops under two feet high when finnished ensures good light penetration and the need for more powerfull and costly lamps to run, combine this with 36 plants per meter square, and you have 350 to 400 grams under a 400 watt hps, no probs, each plant only has to produce ten grams of dry bud to make 360 grams! the idea is to maintain the plants on one cola![bud] again the room needed for a ten gram plant is minimal, and if you guard the plant tank from the light, the roots will grow out of the bottom of the pots into an inch of sollution that should be left in the plant tank always!, when removing the plants for cultivation the roots form a blancket over the bottom of the tank!
good luck with your grow
welcome to the world of endless possibilities,,,,,,hydroponics!
Thanks for the tip Mistyg!
I thought my bed seemed a little big for SoG, I think I'll just have 20 plants in a square meter.
I might not have the money for a full hydro set up at the moment, so I'll probably just use good old organic soil and my watering can.
If you think a 400 watter can cover 4x4 you must be keepin that light LOW as hell. mine gets close to 4x4 but it doesn't pump the plants enough, bigger is better. whatever you get, go with a grolux bulb by sylvy.
Peace.
I HAVE A 4X4 ROOM WITH 3 600 AIR TUUBES 4 TOWERS 4 SITES PER TOWER 20 PLANTS LOOK AT THESE PICS 19 DAYS INTO FLOWERING GOING NUTS
Damn! That's some mad science shit you got going on there. never seen so much bud in such a small space. I guess you don't even need a reflector for your lights seeing as you have plants growing all around the lights.
That's def one of the coolest set ups I've ever seen.
THANK YOU THIS I THE FIRST GO ARUND WITH THIS SETUP AND ILL NEVER GROW ANY DIFF AGAIN HOPEING FOR 3+LBS THESE PICS I TOOK YESTERDAY 19 DAYS INTO FLOWER
Go with the 600. My area is 4.5X4.5 and have grown with a 400, a 600, 400+600 and 600+600. Now i always use the 2X600 and get huge yields.
you cant beat 600Quote:

:stoned: 1 600w at 24hour cycle thats about 3.5 amps. I have 3 6oow thats about 11 amps ab out $250 more a mounth for all the power i draw for my entire room
my room ic 4x4x9 i have 3 600w in a cool tube ventings fine but im always tieing back once or twice a day so they dont burn.What do you think aboutQuote:

need input please
thanks J
P.S I NEED 3 FOR THE HIGHT
always go for the big 6
90,000 lu +
youll be impressed
closet mate
switching to 400's will cost 1000's of lu's
cannot see the benifits myself
apart from the fact the the amount of light your plants recive may not be the limiting factor to size of the yeild now youve gone all supernova style
thats a fukin boss setup you got youself there
keep up the good work
Question, how much would a single a) 400 w HPS bulb b) 600 w HPS buld cost per month if my rate is 0.15 a kilowatt hour @ 18/6?
dont worry about leccy mate
a 600w hps in a perfect enviroment should return 300-600g off top quality sensi buds every 12-14 weeks
10-20oz @ £100-£160 per oz
= no problem finding 50p for the meter
crack on mate
love buddy
follow my advice
be skint and try to smoke 2 oz a week :rasta:
THANKS I SPENT ALOT OF T&M ON ITQuote:
