Hi, Shane here. Thanks for watching, Please hit the like button and subscribe here: www.youtube.com/@MIGROLIGHT?sub_confirmation=1 Buy my Grow Lights here: migrolight.com/ Follow us on: Instagram:instagram.com/migrolight/ Facebook: facebook.com/MIGROLIGHT/ TikTok: www.tiktok.com/@migrolight

im saving to buy the Aray 4 for my 2x4 even if there might be something better out there in the market just for the simple reason that Shane has been so transparent and honest with his reviews and for being an amazing person, i feel like the light value goes beyond the product itself.

Well done, Shane. You've got a knack for breaking these things down to simple terms and numbers so everyone can understand. Keep up the great work.

Hello from New Zealand, you channel provides some great knowledge, We appreciate the time you put into these Videos Thanks.

Now I understand why you tested your Migro Aray 2 lower than the other ones in your previous video. Thanks!

Excellent information Shane thanks for putting these video's together

congratulation on 100,000 subscribers xx

I find your tips and guides very informative, usefull and accurate I have watched a lot and refer my mates keep it up mate

I use the Grow300. I like to hang the light high as I can in my tent. And dim the light up or down using the PAR reader spotOn. I start about 200 with seedlings and adjust the par reading from there.

This is really good content. Scientific, concise and clear. Love it.

Thanks for sharing alot of people leave out this information 👍🏿

Nice work migro, as always.

I was just making a similar video. I'm gonna have to do another take and name drop you and this video to help share knowledge. The more you know the more you grow 😆

Everything I'm wondering about you got a video on it; great! I'm looking to overpower my lights just a tad for my size tent so I can have a bit more distance and reach excellent uniform numbers dimmed, and use two instead of one so I get corner to corner coverage as most LEDS do drop off significantly once you're out under the board and large boards usually have a big hot spot in the centre.

glad u had a sweet holiday with the family.... your wife is a treasured gal

you said lots of web sites like yours ..nah you got that little more quality and info then any other migro sets the par ...good stuff

just picked up a Viparspectra P4000 with your discount code. Cheers!

loving my aray pro, i also have the vipar 1500 in my veg room.

Led gardener is a really good guy I learnt alot building lights from him

Thanks!

Very informative 🌱thank you

I believe there need to be a conversation about ppfd 12 inches away from optimal distance. How well does the par hold up at greater distance. That effects canopy penetration.

thank you!

Thank you so much! Is there any possibility you have all your material saved? I'd want to download all of it and have it on a physical copy, you have the best material on the net at the moment.

What I find kinda funny, all those lights are dimmable and tonns of people are making a huge fuss about that function but yet, I NEVER FREAKIN EVER see that function being used in a test, just hight adjustments! WHY? For the XS1500 e.g. how about 14" hight and dimm it down a bit to get rid of that 1.2K hotspot? For the 3 provided charts 14" looks like the sweetspot, except for that hotspot. Why am I asking? I wouldn´t put more than ONE plant (ya know which one) underneath a single XS1500, 2x2 is just perfect for a single plant using low or very low stress method. Got two DarkDevils in a 80x80cm tent and there´s not enough space for two more and I´m using just low-stress, not very-low or even extrem-low stress like last time. And for my 80x80cm tent, I got four (4) Vipaspectra P600 inside that tiny tent with the lights hanging closer to the walls/corner for more uniform lightoutput. I looked at the single lamps for that tent, but I simply don´t like their lightspreading, at the sides and in the corners the numbers are WAY to low for my taste (350-400mol?), so screw that 100W less powerdraw, when those lamps easily have 200mol less than four P600 in total. If I positioned them correctly, I should have 800-900mol on the entire area.

I got the sp3000 from Mars hydro n I love this light

Thanks Shane! Curious, do you agree with ramping up DLI during flowering? As an example, one website recommends a DLI of 25, 28, 30, 35, 40, 45 during the 1st thru 6th week of flowering. Or should I hit the plants with a DLI of 45 starting in the first week?

Great channel, Shane. What do you think is required in order to achieve 90%+ uniformity from 8", such as might be desired in vertical arrays? Are secondary optics the best bet if cost is offset by DIY or could it be achieved simply by appropriate coverage end to end? Cheers from Australia

Solid for the knowledge 💯 watching from New Zealand gathering all the knowledge i can to grow potent frosty skunky 420budz

Thanks Shane. What do you think abouth like christmas tree plant ?

The plants kind of tell you. If tops too close they will singe/curl up.

I have been looking at the GLS 850 for purchase and was curious if the light was hung 24" above the canopy if co2 supplementation would be needed or if the light can just be dimmed down? I like the idea of having the higher wattage light for a larger space later. I am currently in an 8 x 8 tent and planned on using two of the GLS 850 for now.

Hi Shane great video ,just if someone had four off the older Migro lights in a 1 m X 1m , in theory ,make hight would you recommend ,as much as I remember you recommend 30cm to 45cm I think ,so would you recommend around 52 to 55cm ,thanks

thanks

We need to see a review of the Lumi Black led that runs off of your old hps balast

This is insanely helpful. I'm growing in a 2x2 on a budget, 1 plant taking up about 2/3 of the tent and it is at the start of late flower with a sf1000 I did some of my own calculations and came to 7.7 inches as the perfect height but I don't have tools to confirm. However, seeing the info here I see I should raise it to 8 inches, and this balances everything a bit better. Really aiming to maximize what I can get out of this single light, this plus vpd have been quite a big change.

Have you done a review on the bestva led lights

Could you please comment on UVA, or do a video about pros and cons?

can you talk more about using the uni-t bluetooth meter with the app, weren't you going to work with the app developer to create a better light profile for that device?

im trying to learn as much about light for my autos but hard as im Dyslexic however i got a ts 1000 for me 2 x 2 tent

Someone told me to always upsize the light. In other words, if you want to garden in a 3'x3' tent, buy a light that is being advertised as adequate for a 4'x4' space. The person went on to say that most companies exaggerate the capabilities of their products - and that, therefore, you're more likely to be able to harvest a crop of fruits and vegetables as if you were growing under the sun (I'm not really much for lettuce, although I am partial to the rabbits that it brings into the backyard ;-) ). He also told me that, when one goes "one size up," one often gets a product that is physically larger, which helps get light to the perimeter of the garden without over-illuminating the middle. I am thinking that HLG did not receive that particular memo. . . .

Great video as usual, information thy name is shane

What would you recommend the hanging height for a spider farmer SE3000 (300w) for mid veg and what dimmer setting ?

If i use a 500w LED at 60cm hanging height - can i go to 30cm when i dim down to 250w?

I go much higher than most hanging recommendations. I go like 20-30 inches above canopy. I find if you are hitting your target ppfd at a higher hanging Hight the light pernitrates farther down to the floor. The ppfd stays higher at lower distances the higher I hang my light to a point. Not to mention better coverage. I run six 240 watt led's each covering about a 3x3 area.

When they say average par for the footprint, is that full power? The light I have has 4 dim settings. And hang 36, in

So I can get as close as I can safely as long as the par is correct?

@ 8:12 ...just the other day I was wondering about CO2 levels. It can't be that simple. I had planned to spent many hours with Dr Bruce Bugbee videos to figure that out.

Hello, great info as usual, thank you Shane. I love the Aray line 4 the simple clean design and assemble, less is more... would luv it on my kitchen table. Question: when u drop the distance from top off canopy u loose some penetration, say u start with 800 at 18"... 400 at 36" etc. The further way from tops the better u deal with a thicker plant... so cobs for deeper canopy and panels for a sea of green style?!

What do you think about using an infra red thermometer to check temp of canopy? Not exact but trying to keep leaves within a couple of degrees of ambient temp for stomata max suckage? Your channel is amazing. Thank you

A quick glance though their chats tells me to stay away from anything that isn't a bar light. the hot spots really show when your looking for/at extreamly low hanging hights.

Do one for the Horticulture light 135 Rspec. PLEASE what should be the distance

lunatek 600 pro 2.9 grazie

That's why I get a bit dissapointed with the par tests, we need real world scenarios. Have an even spread in a 4x4 and 5x5 and those numbers are the real efficacy. What am I going to sprout a seed in the corner of a 4x4 while the middle needs CO2 because it's hitting 1200 flowering? We need even spread and real world numbers full stop

Hi Shane, When using a quantum sensor is there a rule of thumb to follow to work out light distance verse intensity , an average ?

Oh yes🤗🤗😁😁🤗🤗😁😁👏👏👏

got one 240w light using 2000 diodes and another 240w using only 500 of the same diodes..obviously have the one with more closer but it wont grow a taller plant .. like ive asked on every video whats the par at 4 foot..the canopy will always be great numbers.but am sure at 4 foot the one using more diodes will be utter rubbish

With migro array 2 pro do you recommend keeping height at 18cm for autoflower and what dimmer settings do you suggest in each stage for autoflower. Can you release par maps for each dimmer number or is it as simple as 50% on dimmer will half all numbers on map at same height

Any lights you can recommend that have their own supports (do not need to be hung?)

💡

I’m all about uniformity. Used the smaller 150 watt QBs 4 to a 4x4 for years till bar lights got their pricing to be reasonable. SE7000 in 4x4 2 SE3000s in a 3x5 1 Marshydro FC4800 in a 3x3 1 mars hydro SP3000 in a 2x4 And 3 150 watt Viparspecta XS1500s in a 2.5 x5 LED gardener shows the XS1500 blows the doors off a 2x2 18 inches is perfect in 2x2

Hello i have 4 , 450 watt quantum boards basically full coverage of my 5x5 canopy 1 per plant at 35% power . I couldnt think of a way to get a more even spread . Any thoughts ?

so your 3 bar... 6inch to 9 inch? also, would running x3 3 bars in a 2x1m space at the recommended hight on a lower power become more efficient than the recommended x2 3 bars at a higher height? i hope that made sense! thanks

i have a light that i can set the PAR via adjustments so what is the recommended distance i should hang the light off the canopy for seedling. veg and flower?

Do you measure distance from the floor or from the top of the soil/growing medium?

Why can 1000 ppfd make it to much with led but when in full sun it's easily 2000 ppfd?

3x3 with se 3000 led Flower at 18 inches @100% 2- 5 gallon pots Any suggestions or am I good? Thank You in advance. Definitely Subbed 💯

What should the readings be on a quantum lux meter for grow I burnt my leaves 2x 200watt @ 420 micro mil each

Because you look like you grow loads bro

Hang them high and turn them up. It works for me. Led of course.

I'm so f'n tired of having over 1000 options for literally every product I want to buy. What a bloody nightmare. Unless the product you're selling is top notch quality you shouldn't even be able to sell it. You got 700watt lights that range from $200 to $2000. Like how stupid.

I have a viparspectra xs4000 in a 2x4. Supposedly it’s for a larger area. They say hang at 18-24. So I’m not sure where to hang mine

If an optimal height is determined at 100% power, does the uniformity remain more or less the same, as the light is dimmed?

almost successfully grown a cucumber under 130k lux in a hydroponic system. From practical experience I will say that the allowable distance depends entirely on the temperature of the air zone. if ventilation is sufficient, then the leaves begin to burn only in the immediate vicinity of 1-5 cm

8:55 16 inches are not 45cm but 40.5cm

i like my lights at 80 percent power

So Sanlight refused to pay you.?

I bought the GeekBeast light that you consider a top value. The one I ordered was supposed to be for Flowering. (weather it was or not, I don't know.) I ordered the longer driver cord and the 240 plug neither cam with the order. When I contacted them, they said that was too bad. It would be nice if companies made lights specially for either grow or Flower. Also it would be nice if you said something about Customer Service as anyone who ever dealt with Spider Farmer, there is no such thing.

✌️✌️

Why will numbers over 1,000 PAR cause light burn but not with CO2? does CO2 prevent burn?

600 rspec isnt a 5x5 light, simple as that. Not powerwise and not spreadwise. That just 260 watts/sqmeter

Based on doing cuttings of the same plant would render bar lights useless most people are doing seeds these days that would buy these lights However the HLG style lights give you a bigger scope as hanging height is more forgiving Me my self own a sf 7000 similar in design but not the best spectrum for flowering so I added 250 watt osram hps and turned led down to 70% and what a difference in a 3x3 prior to that had spectrum king sk-600 before that I had 2 600s in cool tubes so changed days

I hardly understand your language, but is there a leaflet somewhere to read it? is that ok a marshydro 600 at 50cm from the top of the plant or should I lower it to 35cm? vegetarian 25days !
