What is a Grow/Plant Light? Do You Need One?

[@EyesOnReality]

Yes, super informative in all vital details. Just the kind of video I wish I had about three years ago, saving tens of hours of research, finding all the details listed in this one video. Great Job! Also, yes, the Kevin spectrum temperature 2800 to 3500 (floodlights) was settled on after many growing experiments, doing great for veg right up to bloom by just changing the light time cycle (for those Mari-Pickles you know). Thanks for sharing, confirming my findings and providing a learning boost forward to those just learning. Your time and effort is greatly appreciated!

[@Batsnang]

Thank you for this info! New to indoor growing, found a white LED shop light at 5000k for $30, 4ft long with a 5-year warranty thanks to this info. Definitely saving a penny there over the nice blurple ones!

[@roxane1237]

Care to share your experience after 2 years ? :)

[@rafaeldeam]

Thanks for sharing your knowledge and experience with this confusing matter. Cheers from Brazil.

[@kimwarburton8490]

Thankyou for the info, converting my lounge to a growroom xD

[@Didolinas]

Tks a lot!!! I'm a nuclear chilli grower from Brazil. Specializing in 'nuclears', crossing whith my (Brazilian) native chillies trying to give resistance/flavour and big pods. Somehow the plants, as you said, need the whole spectrum. Make sense. They evolved this way. Thanks for your experiments!!! I will send mine!!!

[@bbyrneish]

I want that light! I’ve used lots and lots of lights through the years myself. I like lights like that for starting new babies!

[@sixgrigsby8615]

Thanks for the explanation of grow lights and in a simple form and yes I would like to try that light 💡

[@lelouchlamperouge4273]

you weren't boring i could really use that light thank you.

[@TomPalissade]

I agreed long time ago, as a photographer, measuring with a lux meter I couldn't understand how a two color light could be more efficient than a full spectrum one. Now we can find 50 or 100 watts LED Flood lights for $5 or $7 including shipping on online shops

[@booom2314]

0:46 yes, turn off the flickering light. 😅

[@peterpan420247]

That is due to the frequency of the light. It is not for cameras.

[@booom2314]

@@peterpan420247 ja I know (that it ist property caused by the power supply of the light or PWM) but it is still a flickering light in my eyes because my "eyes" are the camera. have a nice day :)

@@peterpan420247 Its was actually a flame light. Nice in person, distracting in videos.

FINALLY someone else not buying into these blurplel lights. It is so much more complicated than just picking 2 colors nothing in nature grows under a blurplel sun!!

[@Pockymuncher888]

This was helpful thanks. I ended up buying a MARS HYDRO TS 600W to grow basil, cilantro and a few other herbs, Any thoughts on that light?

HOW ABOUT NO good eco light

[@llllllblodllllll]

:O OMG Light giveaway! Yes please, yes please,yes please, yes please, yes please! :D Your videos are always very informative, I actually paused this to watch the temp room creation linked at the top right. However, that only informed me of my own inadequacy as a human... and how The Flash should actually look minus some motion blur. Another great video, please don't stop. And thanks again for taking the time to respond to my previous questions, it's really appreciated.

I got the GE 4.75-in 1-Light White 9-Watt Br30 LED Grow Light, it seems to not hardly work at all. My best indoor plants are the ones I put in front of a large window with a white curtain behind them. They must spend half as much time in strong light, but grow so much faster.

[@yojimbo9310]

Thanks fer clearing that up

[@TomPalissade]

Just for joking, it really amusing me to listen to a plant lamps specialist that did not understand yet how to set its camera on the same frequency as it's lights. Flickering can be avoided, try 25 or 30 frames per sec to see what happens 😉

[@independentthinker9113]

Thank you so much for this information! Yes, I'd like the light that you are giving away.

[@mattrooyakkers5871]

The curtain could use a change.. Good info

[@rnyk82]

Thanks for all the video and i have learn how go grow with all the lights and growing technique you have taught. The one I like most is the aeroponic diy which I have set it up following your instruction. I have my melon growing with big leaves under blue red light from sansi. I have expanded the aeroponic to growing larger plant like chilli and passion fruits. But I have been seeing you using white grow light which I wanted to try it out. Hence I would like to get that from you. However I am in Singapore and willing to pay for the shipment.

[@arrowgunt]

oh can you do us a favor and talk about ec/tds my tap water has an ec of 0.5 there is a lot of calcium in the water I've heard that plants can't absorb that kind of calcium. I forgot why though. But I don't get whythe gh flora series has two different types of flora micro series one for hard- one for soft water I would like to know what's up with that maybe one experiment with ro water vs tap water

[@GrowingAnswers]

ZFofficeonly I have used both. You really only need the tap water version if your tds is above 150ppm-ish. Other than that, the regular stuff Is fine. The calcium in tap water is a larger molecule and doesnt adsorb as easily as what’s in the flora series.

[@kamnapivo]

thanks for that... just wanted to know what light should i buy to propagate seedlings.. so LED T5 now just decision if 3k 4k or 6.4k

[@kamnapivo]

oh yeh got an answer at the end of video 3k-4k...so now if 2400 lumens is enought for 2sqft.. probably not

[@GrowingAnswers]

Jan Faix forget about lumens. Just put them closer to the plants. You won’t burn them with led tubes.

[@kamnapivo]

@@GrowingAnswers great thanks, I am just on yours LUX vs PAR Meter | Can You Use a Lux Meter with Grow Lights? looking for answers...just wanted to know intensity to avoid leggy plants as I always have on widowsill... cheers

[@GrowingAnswers]

Jan Faix just pay attention to the plants. Place the tube light about 2 inches away from the seedlings before they sprout. If they reach then bring the light closer.

[@kamnapivo]

This was very informative and exactly what I have been searching for now for a few weeks. I have put that spectroscope on order and will test out the 4' GE LED T8 lights I just bought in a bulk 10pk box for $74 at Lowes. Thank you. If I am just planning to grow lettuce and kale and other leafy greens... what color spectrum should I use?

[@GrowingAnswers]

MySuburbanHomestead 4000k or mix 5/6000k with 3000k. If you don’t have any other plans for the lights, try to remove the frosted diffusers or cut them open to increase the efficiency.

[@great0789]

@@GrowingAnswers Thank you for the quick reply! I have two 10 packs at 6500k. I will take one back and make a trade for a lower kelvin rated one to mix them up. I don't know about cutting them up. Inside they look like they just have a light strip that was glued inside the tube (I assume). I guess I won't know until I popp one open though. lol Downside is according to GE some of their bulbs are glass and some are polycarbonate. I can't tell just by holding them.

[@GrowingAnswers]

MySuburbanHomestead it it feels cold it’s glass. Tapping on it is a pretty sure way to tell.

[@great0789]

@@GrowingAnswers They are glass. I will to a swap for lower kelvin rated bulbs. Might to a test on the 6500k with that meter I just order from Amazon first... then do a test on the 5000k/other bulbs I get.

Lights are supposed to be on 24/7 or I can switch them off during the night? Also, mb someone knows, if I have a lot of sunlight from transparent roof do I need to buy more lights?

[@GrowingAnswers]

plants need a rest. turn lights off at night. some growers will veg a plant on a 24 schedule, but thats not something i agree with for many reasons. A transparent roof with direct sunlight is essentially a greenhouse. supplemental lighting for that will vary based on the circumstances

I’ve tried growing water grass in a fish tank. It doesn’t matter what color light it is. The lighting intensity is what matters in a fish tank. Well let me rephrase that… It doesn’t matterWhether it’s red blue blurple or white light.

@GrowingAnswers plssssss help me here i am going nuts here. So I am wanting to buy myself a 1.5ft x 1.5ft grow tent and cannabis needs 50w light per foot to grow. So 1.5 x 2 = 3 x 50w = 150w actual wattage from led light. but then what rated wattage led would you need then exactly?? is a 600w rated led light equivalent to 150w actual wattage or what? pls help me here, what size wattage led do i need?? thanks

[@GrowingAnswers]

You don’t go by wattage. That is a very old technique.

[@deevital]

@@GrowingAnswers Yes i get that, but still a bit confused. i understand the wattage thing. And the actual true wattage of leds as oppossed to their rated wattage power. I have searched all the internet, and they all speak about this wattage and space coverage, please help me with the solution!

[@GrowingAnswers]

@@deevital The manufacturer or sales company that sells lights usually provide a par footprint map. That’s all you need to go by. Overall par measurement over the canopy usually needs to be between 500 and 700 micromole. Center par no more than 1000. Companies usually provide those maps along with height differences as well.
