everyone "knows" this, everyone parrots it.
Ive only ever growed with 3 x 600w HPS, so i know it too.
I want to understand the technology, not pass judgement on it
IF this is true then why are the 3w LEDs considered better than the 1W LEDs that are better again than the smaller again LEDs?
Theres a law somewhere that states that the light intensity halves over a distance of X. So at distance of X it is half of what was produced, at 2x its a 1/4 and at 3x...
Fascinating. So all the science points LED, and yet people scream how much they suck. Doesnt add up.
I can only put it down to starting with such low lumen output (per LED) means that the light weakens to something useless too quickly (aka no penetration).
But if the actual LEDs themselves...
isnt the problem that most grow lights are 1w or 3w LEDs and lack penetration?
isnt that a 80w LED and as a outdoor floodlight it should have mass penetration?
thats my question. (well that and why people question LEDs if they are twice as electricity effective)
im in australia and i have bought cheap T5 LEDs from them with no worries (cost me $25) and works fine
The striplight i bought is a 8w T5 (thats 8w real electricity used) and puts out 550-620 lumens @ 5500-6000k spectrum. They can be gang wired in a line easily with a supplied adaptor...
Ok so the simpleton tries again :
LED : 90w : 436 light units : 4.84 light/w
HPS : 280w : 700 light units : 2.5 light/w
when you look at the amount of money that is involved (either selling or for self) a few hundred dollars isnt that much. As you said :
when you consider that you buy a...
I found some LED flood lights that advertise 2 x 80w LEDS.
From what i understand the biggest LED currently runs at 3w.
It also advertises a 160 w light and has a power draw of 160w unlike most other that state thet are say 450w but really draw 150w (or whatever)
Its a flood light which implies...
Im a bit of a simpleton, but from the first post i read :
the LED with 120w (90w) produced 436 units of light.
the HPS with 250w produced 507 units of light.
my basic maths came up with :
LED : 120w (90w) : 436 light units : 3.63 light/w (4.84 light/w)
HPS : 250w : 507 light units : 2.028...
74.4 oz total / 3 lights = 24.8 oz or 701.84 g per light
1.17 gpw
64 oz total / 2 lights = 32 oz or 905.6 g per light
1.51 gpw
The shit seriously out performed the critical mass
i just gave up.
i can get them from the USA : http://www.ebay.com.au/itm/Black-red...item35b56bce74
and i can get them from Europe : http://www.sanniesshop.com/root-pouch.html or http://www.nirvanashop.com/en/853-root-pouch-5-pack.html
and i thought about convincing my local hydro shop to buy a...
querkle got in the list of top 10 strongest strains of all time list in some high times mag apparently
that shit lays people out, people who have smoked for years.
bump an old thread!
if i was to do the "bucket with holes inside another bucket" air pruning method, what would happen if i just left it in there and didnt take it out. sometimes its hard to get to plants in the back when theres retic hose everywhere.
also the option of "bucket with holes"...
hey guys!
im interested in smart pots, or something similar.
im in australia, cant seem to find them
i came across oregon breathers, seem similar, on ebay, but they cost a fortune sent from the USA ...
