Re: CajunCelt's Multi Strain - Darkstar - Chiesel - Kush - Red Purps - THC Bomb & Mor
My recommended distance for this light & these strains is 20". Any lower, I was burning leaves & coverage loss began to be noticeable on the edges of the tent.
That said, this is not enough light for a full 4'x4' tent in my 2 grows of experience with it.
I grow & train to have flower canopies, not plant canopies, so I use every square inch, equally, of a grow space.
That said, the middle of the tent has HID-like growth, but as you move to the edges, the growth is noticeably smaller. The optimal footprint of this light is rectangular, not square, and it is not 4' x 4'. More like 3'-6" x 2'-6".
A single of these would be good for a single big plant or 2 in a big (4x4) space, but not a scrog-like grow.
My 600w HPS did a similar job. The differences I see at this point are:
The HPS bud is bigger, but not much & not as much lower (useable) growth.
I would need 2 smaller lights (or 1 more of these) to get the most of my grow space.
The HID setup uses more, is louder, & the plants are less lush/healthy as the growth under the LED setups.
Conclusion: I'm sticking with LED, but need another light for my specific usual space, 4'x4' & 5'x5' tents, to get the max out of the space.
The growing cycles under LED are superior than HID. It's a friendlier environment & makes HPS/MH seem like a desert.
The lack of fans & noise making shit sold me week 1.
The last week or 2 when the flowers are finishing is another phase where LED excels. The trich growth is pretty crazy.
Oh man, the lack of heat is kinda new. Actually takes some getting used to. I miss huddling up in the grow space during winter for warmth. But not really. Lol.
