Mars-Hydro LED Grow Light Discussion

hps may have more uv. I was thinking to hang a couple uvb reptile bulbs. Unfortunately you may shorten the grow cycle with the uvb as the leaves will start to yellow . Cellular apoptosis from the uvb (read link below in sig and draw your own conclusion. THought I read something about leaves yellowing when UVB was applied for 6 hours a day towards end of flower cycle , more trichomes and more yellowing. THis is why the UVB is not applied full strength too soon perhaps. JM2Cents. 🙇

I was hoping you were not going to say that. Be nice if you guys could stock a few in the warehouse. Us farmers love some reasonable side lights. Thanks Sara...

The side with more light did better. Put another more powerful led on the side opposite the hps so they have the same amount of light and it wouldn't look like that.

I'm thinking it was because hps Offers more uv and ir rays. I am going to hang another 60x5 on the other side of my mars 1200

We should make some of our own supplement bars with more uv and IR. And red. Just for bloom.

I would get at least a 4 inch inline fan and filter. If your growing area is pretty hot you can bump it up to a 6 inch with a speed controler so you could find that sweet spot for temps in your tent. Your light and tent should be a pretty good combo.

Hi there, now I ordered the Mars II 900W (with bloom/growth switches) and a 3' 3''x 3' 3''x 5' 11'' Grow Tent from Mars Hydro, together for 427.- USD (LG-LED SOLUTIONS LIMITED)

What kind of fan, (carbon)filter etc. do I need for this tent/lamp, any suggestions?

Thanks a lot for your help, you're GREAT :thanks:

I was going only turn on the uvb For 45-30 min after the main lights go off and see how that does.

Thanks for droppin by and for the kind words Sara.

I see on the Mars web page that your sidelights a asked for some time back, have been put up there now great. but it says it is only sold in holesale why is this? i would love to install one or maybe two in the closet some day to support the undergrowth a bit more than the top lights are capable of. you do not need maybe a tester on one of the smallest just? *LOL*

seriously how can i order one at some point? i currently does not have the storage space for a 20ft container containing 300 lights :P in my 60ft2 sized miniature apartment. :D Im actually thinking about buying a small reflector more when the money is for it. so i could make a small cabinet more so i have a bit extra as a supplement to the other closet cus i have a hard time keeping up with the demand from different sick people wanting to try out cannabis at this time. currently i used all my own meds on them (im an idiot sometimes lol) so i need to upscale a bit. if i order that extra reflector from your site at some point could i maybe order one of those small bars with the same pakage maybe?

also in the long run i think those small bars would be very good for my nursery and veg room in bottom of the closet as well.

oh yeah BTW did you redesign the webpage? it is really informative and great looking now i think it was not like this last time i looked maybe?

Hello there i am on my first medical grow right now and i have a gorilla tent that is about the same size 3x3x5'9" with a 900 Mars II and i bought this complete kit and it works amazingly. Just set up the fan and filter on the outside of your tent to save yourself vertical space because of the smaller tent. Good luck :) https://hydrobuilder.com/covert-car...ntilation-and-odor-control-package-14563.html

im pretty sure you need that carbon filter inside the tent. im pretty sure it should be better for sucking air in true it than pushing it out off. not 100% sure but pretty damn sure :)in ten years i have never seen them outside
 
To add my 2 cents worth..
add a 4 inch vent fan on a controller you do not want to much neg pressure inside your tent you will draw in any critter who gets near the opening... with such a small area a carbon filter is not needed just a a addnl expense not really needed. get a odor absorber like ONO gel or similar will keep the smell gone from the inside ONO can be found on ebay as well as janitorial supply houses
I am new to LED's for full cycle use have used them with grow with excellent results
I am currently using 3x 133x5 reflectors to replace a 1k I use to flower I will post pics soon as I had promised Cecilia I would when she gave Me the deal on My reflectors. I do appreciate the comments I have seen on this thread and hope to learn more as I share My experiences with you as well so far the stretch is done plenty of healthy bud sites
Be Well
 
Here is the beginning of week three in the 3x3x5'9" Gorilla Tent with a Mars II 900 Led light. 3 Blue Dream and 1 Green love potion all in 3 gallon smart pots and 1 Buddha's gift in a 1 gallon smart pot. The second picture is the Advanced nutrients i am doing this week. This week Bud Blood stopped and was replaced by the B-52 and the Sensi grow has been since week 1 and the big bud since week 2 :high-five: and i just finished lolipopping them so i am expecting the buds to start exploding soon

So I'm a lil over a week into veg and getting cal mag issues. I use distilled watter since my tap has to much dissolved solids. Got me some calmag into this feeding. Soil ph is 6.2 so I shouldn't have a nute lock. Think my distilled watter is the issue.

yeah i fully agree 4 inch vent for that small a space would be fine but i think he already have the vent and filter? but maybe add the controller? i mounted a temp controller i connected my 4 inch vent to for less than 8 bucks with the postage and a rpm controller for 7 bucks. so my little cabinet stays stable no matter the room temps around it and such. next project is to make an alloy cooling device to mount to my active intake on the back of my cabinet before summer :) looking forward to that project its gonna be awesome to try.

do you not put up mosquito mesh or some type of air sock to avoid the critters btw?

if your getting Calcium deficiency in week one veg :hmmm: maybe don't use destilled water, tap water mixed with the destiled maybe to get a desent mix? should have some calsium in it. were i live i have to use special hardwater nutes apparently ph is above way 8. so maybe just normal water mixed a bit even tho you say its not so good, is it waaaaay bad m8? what do you other guys think? must say i never had that issue one week into veg would it not be strong for such a young plant with additives so soon?
