Can anyone help me figure out what's wrong with this girl, I have 11 other girls same nutrients same light same everything thriving. Should I just kill her off? The o KY thing I can think off is that she didn't like her heavy defoliation.

these are all 11 others

Hi geopv, the leaves are drooping. Maybe it's overwatering... Don't kill her. She will survive. I believe later more exprienced growers will give you some suggestions.

Hey Klovneposen that does look lovely!

I would love to try dwc, but im stuck with soil as my medium really (cant afford more nutes etc) But thanks for the idea! So you think i might be able have it a little lower possibly? For air circ,,, being microish and all would be a 9" fan across the plants - but only a 120mm pc fan as exhaust/passive intake - would that cause more probs?

I was thinking though, if i hung the led say 1" or 2" from the roof of it, with the 9" pot - at seedling stage i would have about 24" to the light. The plant could grow to 12" to keep the led 12" away. I would lst and (Attempt to first time ever) scrog. I could put an inch less of soil in the pots and get maybe an extra inch at a push.

It's either go with this led - or just use a 200w cfl in a 26" cab (they have to be trained in there to about 12" aswell)

Could i ask aswell, how is the fan noise on them as its kind of stealthy!

I'd love to get the reflector 48 in that 34" cab if i could.

Yes i think it is doable for you to grow in that space with the reflector series 48 for sure. and to start it will be fine with soil also but some non soil grow on long term would properly be preferable. to give you more space for the canopy and buds instead of all that soil in that small space

As for you air intake/exhaust. Pc fans can do okay i have used them in my current closet for a year. but remember if using passive intake you need about 3 times ( a bare minimum two times at least) as big a passive intake hole to keep up with an active exhaust and get the propper airflow. If you can find some extra cheap PC fans i think it would be better with at least one active intake and one active exhaust maybe two if the fans are not so effecient. its gets hot pretty quick in those small closets if there is not propper airmovement. but i think with only one of the 48x5 to start with. It will not get so hot.

if you hang the led 1-2 inch from the roof just don't mount your exhaust just above the lamp as that will conflict with the lamps air intake. The room exgaust will pull hot air up around were your lamp gets the cool air. if that makes any sense. in my closet you can see i have put some flextubing and it sucks the air inbetween the lamps hot air exhaust in the sites instead of just above it. seems to work much better on room temps and i think the lamps runs a bit cooler this way also when they do not have to cool with already hot and damp air. hope this makes sense and does not just confuse you.

lst is def. the way to go in your closet to optimize your yield

oh yeah regarding fan noise it makes the sound of a low prised pc fan so its not too noise but not all stealthy either but buy a silect pcfan and mount youself into it at some point if you find the noise too loud it will cost you 10-15 bucks or so. i don't find them to noisy sounds like my desktop pc when running battlefield 4. i would think

Regarding using a 200w cfl. it will run as hot as the led lamp im sure. i have a friend who insisted on that the closet i build for him was cfl not led and it got pretty hot with a 250w cfl in the summers. and i am sure yield wise you will get as good as if not better result with just 1 48x5 a white widow was under the other panel. first plant i flowered under the 48x5 w panel flowered the first 14 days under a 90 w ufo then got under the 48x5 for 45-50 days it pulled in 103g dried trimmed bud plus 4g popcorn buds and some trimming. after almost tree weeks drying

the white widow cutting was not so big but got pretty massive buds aswell 56g dry

They were grown in lightmix soil and with the biobizz nutes


best of luck with it m8 if any questions pop up you think i can be of assistance with just holla

 

[Klovneposen]

I'll tell you this at 12 inches from the light your plans are going to bleach. I'm in flower and have mine at 18 inches. LEDs are alot more powerful than cfl and cannot be as close. But LEDs have much greater penetration

Sent from my Nexus 6 using 420

my plants does not bleach with the 48x5 when i flower at 12 inches. i don't know with under 12 inch but mine have been at the 12-13 inch all tree times i have flowered with these panels and never bleached. so it is doable to make a closet 34 inch with a 48x5 installed but it would be preferable to do it with a dwc type diy bedroller device and a heavy training regime so he can get as much growspace and distance as possible jmo

he will also be using way less wattage then you are talking about using pr. Square feet. 80wattage i seem to recollect you talking about back in december some time in here. using a 2x2 ft tent i think you said. i could imagine that would leed to bleaching at 12 inch distance.

but not with a 48x5 w using about 100w lets say he got this panel hanging at 12 inches it will give an effecient fotprint being about 2ft x 1.5ft or something like that thats a total around 33w pr feet. just about minimums being 30w if i remember the dialogue you guys had in here back in december at some point correctly.

Yeah that's a ton of defoliation. The plan still uses those fan leaves to collect light and transpire. Only pull off leaves that are blocking buds. Or are having health issues. The plant is in shock. It may still grow bit yields are greatly reduced. You can keep it growing if it doesn't die on its own just to have a visual as to why not to pull that many fan leaves off

[Glitch911]

Lots of change in just a week.
First week of flower. 4-5 more to go. One of them hasn't stretched much at all. Has slower growth overall. But the other 4 are nice and health. I do have a bit of light burn from this last weekend. They grew alot in a few days and I wasn't home to move the lights but its minor and I think things will be just fine.

Holy bejeebus! That White Widow looks fantastic!

I would love to use other than soil (i too would be using biobizz light or allmix) Just with the cost of the diy/nutes atm (super broke atm - so am kinda pushing it for the led £90 compared to £40 for the cfls) But its just the results like you have shown have blown me away! In my micro cab i was lucky to get 12-15g dry on one auto with cfls.

I would prob use a 120mm as exhaust (top right or left) with 120mm fan and x2 120mm passive intakes at the bottom.

Thats great to know on the heat output - makes me much less worried of excess temps, also it would be close to my computer so that should cancel out the noise too This is all for personal, so i would have 2 or 3 small autos in there at max

my plants does not bleach with the 48x5 when i flower at 12 inches. i don't know with under 12 inch but mine have been at the 12-13 inch all tree times i have flowered with these panels and never bleached. so it is doable to make a closet 34 inch with a 48x5 installed but it would be preferable to do it with a dwc type diy bedroller device and a heavy training regime so he can get as much growspace and distance as possible jmo

Thank you so much for the pictures - its a huge help Klovneposen The actual dimensions would be 34"(h)x21"(d)x21"(w) - i could always lay a screen of blackout/mylar if there was excess room being used. I'd prob try to mount the led about 1 or 2" from the top of the cab (as high as poss really)

Cheers so much for all this advice, everyone on here has been wonderful really as i was confused from just using cfls and not really knowing of leds (but ofc all of your plants were making me drool!)

 

[Ogug]

Hi Ogug, for the noise, it differs from people. The sound is not loud. Some people will feel quite whille some couldn't accept it. Personally, I think it's not noisy.

Thanks for the help SmokeSara! Could i just ask one last question (for now ) For your packaging in europe, does it come in plain packaging from ebay/amazon from marshydro-uk/lgledsolutions-uk? Also are they delivered courier/dhl etc, or does it come through the normal mail service?

 

[tinygrow]

Hi guys, Hi SmokeSara !

I'm planning on a small medical grow in a 3x3x7 feet tent. After readings tons and tons of review, Mars Hydro looks like the big winner in term of quality-price grow LED.

I'm not sure between the Mars II 900 and the 1200, what do you think? I know it could be off-topic, but I want the maximum yield with 4 plant in a 3x3x7 tent. I really hope that the 900 is enough, but if you convince me that yield could be significantly better with the 1200 I take it!

I heard that a newer version of Mars II get the bloom-Veg switch. As I live in Canada, will I get this new model? And from where my light will be ship, China or a warehouse in Canada?

I read that there is no repair center in Canada. What we do if a problem happens? Shipping a big package in USA is pretty expensive here. I have to admit that a couple thread about bad customer service and language barrier scared me a little, so thats why I ask questions about it.

I've seen in some post that EBay buyers could get different customer service. Then where should I buy it? And do you get any price discount for the 420 users?

Sorry for the grammar, I'm french

Thanks!

 

[Dennise]

tiny I'm going to jump in here a minute until Sara finds your post... If something does actually go wrong with your unit... I have purchased well over 20 and not a single problem from a single one,,,{knock on wood...} M-H will either try and figure out what parts are needed and send you the parts or they will exchange the unit if fixing it is not a possibility... They have diagrams and everything you could possibly need if it is a self repair.... Sara and the people that help her are amazing at responding immediately to needs or any problems... Next week is Chinese New Year and they will be almost impossible to contact for about a week... So if I was you I would go ahead and get er done... also IMO there is hardly ever to much light... The 900 would give you ~ 50 true watts per sq ft so you would be golden but the larger unit would be even more so IMO........

 

[Dennise]

Oh and as to where to purchase.... I would purchase it from their site listed in Sara's signature... Use the discount code cofinest.......

 

[tinygrow]

Wow fast answer thanks!
