Mars-Hydro LED Grow Light Discussion

[Mars Hydro]

Well, just broke down and ordered my SP-250
Can't wait to get it and grow some primo herb @SmokeSara

Hi Knifemaker420, thank you for the order. Hope you also love them.

 

[Mars Hydro]

Well I lost a bank of lights on my 400 in the veg tent. I decided to pull the trigger on a ts1000 to replace it as a 4/20 gift . When it gets here, I will pull the 400, fix it, and keep it around for a backup.

Hey Dave, great choice to upgrate, I am sure you will love the new light, pull less wattage, but give out more efficient light. As to the 400w, contact us solutions@mars-hydro.com we will still help you fix it.

 

[Mars Hydro]

I'm looking at the ts1000 as well.

It is a great choice, not expensive to try, it also has very stable quality though price is not expensive. Trying to make more cost efficient lights for you all.

I have quite a few Mars lights. My 3x3 flower tent has an EPI320 and my 2x2 has a COB. I have several Mars II and mars 600 sitting storage. Did I really NEED the new light? Not really, but I did want it!!!!

haha, love you! Rock rock Mars Grower!

Hey everyone, with my new sp-250 set to arrive this week (and hopefully my seeds as well) I'm wanting to get a set of protective glasses. On the "Zon" I'm seeing 2 types, ones with green lenses and ones with blue lenses. Looks like the green lenses are for the "blurple" lights. The sp-250 Has full spectrum white lights. What glasses do I want?

The SP light put out white light normal lights, as long as you don't look at the light directly, you don't have to wear glasses, but if you are really need one, I think a sun glasses will work,

 

[Mars Hydro]

I was just wondering because they say they make the blurple light look normal through the green lenses, would everything look green with the full spec white lights?

If you use the led glasses , everything will be green then. The glasses usually are for blurple led grow lights, to help you see the plants in normal color. But since the SP is already white, so sun glasses will be fine,.

 

[Mars Hydro]

Shouldn't, but you could ask @SmokeSara

Yeah, normal led glasses are for blurple led grow lights , to see the plants in normal color, but since the SP is already normal light, the normal sun glasses will also work fine.

Ok good to know, thanks for the info!

I'm looking into these Mars Pro II Epistar lights and everything looks really nice,I'm just worried about the noise that seems to be rated at about 60 dB? I would be interested in hearing the opinions of people who have these units and how loud they seem to you?

Hi Crane, because the panel has fan inside, and it will has noise, but it will be just like the PC fan noise. And as long as you close the tent, the noise is very small.

 

[Mars Hydro]

Cannot wait to see the update.

Ordered Sat, shipped today, scheduled delivery, tomorrow. I love Mars-Hydro!!!!

Got a Mountain Dew bottle handy? Look at the light through both layers of the bottle, lol, does everything look green (yeah, probably)? Seem to work great for blurples - because they attenuate the red and blue, giving you a much more normal view. But the "white light" type illumination is much less unbalanced (in terms of the Mark I eyeball, human), so by doing its job the perception will very likely appear greenish to you with them.

I have a pair, and that is my... er... perception of your perception . I phrased it thusly because my vision isn't-- there was a degree of heredity color-blindness, and then when I was a little tyke, having to amuse myself at times, discovered how... interesting it was to discover the sun as a target for observatino. And then... I got binoculars.

Luckily, I happened to read how early astronomers tended to go functionally blind if they tried observing our home star to much, and stopped. But I (badly) needed eyeglasses by age six, and the vision has declined massively in the decades since. And there's the whole glaucoma thing now.

So I cannot say for sure how YOU will perceive the light through a pair of green-lensed shades, but that's my impression. I don't recall for sure, but I would guess that the blue-lensed ones are for HPS, since those bulbs will be heavy in other colors.

For honest white light, probably a decent set of polarized sunglasses that provide full coverage. The kind you pick up if you have light-sensitive eyes and want to go out in heavy sun, yeah? But IDK for sure on that one, it's just more along the lines of a considered thought. Last Autumn I went through my sunglasses budget trying to find a pair that helped with the blurple stuff. Then the Mars-Hydro rep was kind enough to throw in a pair of their (green) protective eyewear with one of my packages, lol, so that problem was solved but the short of it is that I don't appear to have any normal ones; I think I must have tossed my "street" pair in the box with all the odd-colored cheapos that I'd bought locally trying to find a good blurple pair (which is when I figured out that, if you have nothing better, grab a green pop bottle) .

I have a pair of SP-150 and one TS-1000, and I think they'll compliment each other when used in the same space, plus give me some options; small, young plants can go under one or two, all three for maximum lighting, if necessary I could pull a light as I begin harvesting autoflowering plants (this run will be 100% autos) to flower a photoperiodic plant or two. That last part would be if I choose to start photoperiodic plants before the auto grow is finished and the photos end up trying to overgrow the autos, maybe. Options.

(Im)patiently waiting on my seeds to pop. Just past the 48-hour mark. Temperature is a few degrees below optimum, I'm hoping that's mostly the reason. They're a wee bit older than I would have liked, but I gave each a quick ( <30 second) rinse in regular 3% H₂O₂ before adding the H₂O so as to kill any surface microbes and then add an O₂ boost as it decomposed into the water. Didn't have any sandpaper handy, but this has seemed to help my in the past.

I kind of placed all of my (autoflowering ) eggs into one basket this time. I do have more seeds to replace any that do not grow, but not the variety; mostly DDA and SSDC. Here is my list of hopefuls (all feminized):
1. Critical XXL Auto
2. Auto Northern HOG
3. White Widow Auto (CKS)
4. Blow Mind Auto
5. SSDC
6. Dark Devil Auto
7. Auto Jock Horror x Auto Amnesia
8. Northern Lights Auto
9. Train Wreck Auto

Grow space is a Mars Hydro 39"x39" tent. Decent quality, reasonable price (remember the discount code ), a forum sponsor's product . And, with my choice of lighting, it seemed appropriate, lol. I wish I could afford one of their 28" x 28" ones, too, or a 24" x 48" one. But I've spent my grow budget for the year (and the next, and the next...).

Figured I'd throw up a general update before anyone asks what's up and where I've been. I was away on a job in a rural area with no Internet access (and something called "roaming" on the cell phone, when I felt like climbing a hill and could get a signal at all). I'm back now, likely to stay close to home for most of the remainder of the year. No worries!

Hi TS, thanks for the update! Finally the show begin! Please send us the journal link, will check out!

If you run a decent exhaust fan and carbon filter setup, you probably won't notice. And if you don't feel the need to do that, lol, park the tent somewhere besides next to your bed because the odor from your grow will be "louder" than any noise it will make anyway .

If it's that you fear visitors to the main part of your home might hear, again, your LED fans will probably be quieter than your exhaust setup. If not (or if you want to disguise that, too), consider getting an aquarium and parking it in a prominent location (or directly on the other side of the wall that your grow is behind, I suppose). All the "bubbling" should serve as white noise - and the fish will be more relaxing to look at than whatever they've got running on television this year, lol.

Or get your wife pregnant - a baby can be louder than the explosion of Krakatoa (often between 3:45am and 4:30am) and, as it grows up, nearly as destructive .

If you enjoy - or can at least tolerate it - baroque classical music works well, too. Seems to be a mood-lifter when played as quiet background music and, at 92dB, helps you get stuff done (whatever the stuff happens to be). And if it's loud enough for the neighbors to hear, they might not know how to react (unlike with heavy metal, when the pitchfork and torch brigade tends to come knocking).

That is also what I am thinking, the cooling system will make bigger noise which will cover the light noise, and you might not notice it, haha

I actually just finished moving all the photo plants up to 10 gal GeoPots. They were all started in Vivosun "cheapo" 3 gal fabric pots.
I left the 2 autos in the 3 gal until they finish.

Everyone is basically shoulder-to-shoulder now.

The grow area is roughly 5X8

wow, they are really growing fast Soon you will need a bigger space. haha

Did I mention the new grow from secret grower

Grow two seeds, not successful in the begining, seeds not pop out after soak in water and in the wet peper, then found out it might due to the low temp, transfer the seeds to soil directly and with one SP-250 light one, hanging around 2 feet height. after 5 days, one seed finally germ. Temp is around 28C degree, and RH 58%; didn't use any cooling system for now, and no nutrients used yet, only some water; Time schedule is 18/6. Also there is some vegetable seeds growing up around 4 days. They are loving the lights so far.

Welcome to judge and give advice since it is the first time growing, everything is new! More advice will be much appreciated !

 

[Pennywise]

Looks good so far, shouldn't need nutrients for a week or so.

Cool , thank you Penny for the advice, I hope it will grow healthy and bigger soon!

 

[Pennywise]

It should do well.

I'd probably blow or flick the little droplets of water off of the seedlings, as they can create a "lens" affect for the light. Which is normally not a big deal, I'd expect minor damage at the most and even that depending on the strength of the lighting and its distance from the seedlings - but there isn't much to spare on such small plants, so I'd do it just in case (for peace of mind, perhaps).

I like seeing other types of plants in indoor cannabis grows. This can make for rather expensive produce, though .
