Welcome to the forum 1st
Its a gr8 place to learn and share & full of cool helpful people .
I grew outdoors most seasons of my life and have just switched to indoors , I started under a 600w HPS and harvested 21oz from 1.2 x 1.2 x 2.0 in a 4 month grow at the start of the year ,
This grow ( summer ) had a few more issues with heat ect so the HPS was a no go ,
After tons of research and talking on here and around the net i decided LED was the way forward ,
After even more research and talking on here and around the net i quickly found ALL the led under £600 were never going to match the 600watt hps ,
In the end i went for a migro 400 , Its expensive @£850 but lasts 8 years @ 18/6 , Its fully dimable down to 10% and gives you the option of using just 1 COB right up to ALL 4,
Now ive only had this light a few weeks and am currently just into my 1st flower under it ,
So far i can say is ...
Its efficient And produces less heat than other lights & out preforms them on PAR
Its saves me electric due to less power used hps 600w vs 430ish
creates more usable light than HPS
Less hotspots than HPS
Can customize angle and position of each and every cob for more accurate light
Clearly i cant comment on Grams per watt yet , But according to several different online sources the migro 400 competes with the budmaster and spectrumking but costs £400-£600 less and there is lots of online evidence of 1.5 grams per watt under migro - budmaster - spectrumking
My temps went from 33+ to 24 the day i swapped the lights over ,
You cant even compare HPS vs LED For efficiency its unfair on the HPS lol , I read the other day upto 70% of all the power in a HPS is heat
Thats my 2p worth anyway lol
