Lights for 4x8 - 2 or 3 lights?

[Lilmink]

Looking at HLG Diablo , 650R , 600R. These are 600-650w lights. Will two be enough? I am aiming for 50w/sqft, two 600r would only be 37.5. Is this the right line of thinking ? Any other lights I should be looking at in this price range?

I think 2 would be enough. I have a DIY version of the 650R that they no longer sell. In organic soil, I can easily fry the plants if I don't slowly ramp up the power and feed them heavily.

Have you used LEDs before? What's your growing style? The transition is probably easier if you are not growing organic and can more easily control nutrients from day to day.

Depends on your grow style and environment.

Typically to take advantage of 50w you need everything dialed in perfectly and CO2. Do you have that, or just starting out?

 

[Shaded_One]

50w per square foot of high quality LED is a scary thought when that number was originally being thrown around that was when LEDs were not nearly as bonkers as they are now

My only recommendation would be to go with something bar style vs quantum board

 

[Lilmink]

I have a decent amount of experience. Room is 8x10x8, I have an 4x8 tray , 18 plants in 2 gallon pots Coco coir, drain to waste. Plan to veg 1-2 weeks.

I have the equipment for CO2 but I don't plan on using it for this run. The room is temperature controlled with AC and a dehumidifier.

What is HLG quality that offers a bar style light ?

 

[Moe.Red]

What is your budget?

I like the Raging Kush 2.0 for many reasons.

Lots of folks here run the Spider Farmer SE7000s

There are quite a few options.

 

[Shaded_One]

The raging kush that @Moe.Red runs would work as well but much more on the higher end of the "top of the line" spectrum

 

[Moe.Red]

Nice list man. We should sticky that somewhere.

Shane and the testing he does over @ MIGRO really is some of the most beneficial data to LED consumers out there!

No real budget.. would like to pay for good quality now so I don't have to upgrade

Two 1000w hid tubes dialed down to 600w. 175 each

Or 2 of those 720w spider farmers. 675 each.

Hid or led. . choose wisely lol

I never used hid. Always grown with LED wouldn't go backwards

Crazy that that is the price difference now

I'm only on my 3rd grow so don't take this as disrespect but 2 weeks veg? You're going to spend 2.5 months flowering why don't you veg longer? Just curious is all

With 18 plants in the space. It will take up similar surface area as if I were to veg 6 plants for a couple of months.

The more plants you have the shorter your veg time can be. Its like me running 1 in a 4x4 and having to veg for 1.5 weeks, vs me running 4 and having to veg for 3 weeks. Hes running 18 so yea. Ive seen grow rooms where each plant was basically just one big bud 2 foot up at the top. The more plants you veg the lower your time can be, unless you just want to cut it all out. I havnt had to defoliate any when running 1 plant in a 4x4, but when I ran 4 plants in it, I cut damn near half of it out. So I get it to a point

 

[Lilmink]

Once you have some mother's and you can root clones in 7 days you don't necessarily want to wait for your plants to veg.

Wonder why he does not list the professional level lights

Migro does have very thorough testing videos. If you're really keen watch a few vids. But you might have to watch at 2.0 speed. Dudes super stoned

Yeah I did 17 coco 1 gallon plants last grow .. They didnt grow too tall. Maybe 2.5-3ft max. Strain dependent obviously. You must have some reachers huh? I maxed out horizontal space but had a ton of vertical room left.

edit: it was 13 diff strains so many diff heights

 

[2Bad]

I wandered a bit off topic. What I should of just asked is ...does vertical not matter? Im genuinely asking for myself because I was thinking of vegging longer
