Chinese 150w (38w)+5%?? "Full Spectrum" - Time to discuss this

[tacobean]

Yep so... woops I got one of these \/


Naive enough to buy one during peak excitement, and now that I have spent a week learning about all the variations of lights and how they grow compared to one another I have just a few questions:

The UFO I bought -

Ebay this, its the 45 dollar (cant link yet cos new )

= 150W Full Spectrum UFO LED Grow Light Hydroponic Plant Veg Flower Lighting Lamp


the chinese knock off thats under driven, can I benefit from those wavelengths? that 12500, is that going to negatively effect my plant? should I have this hanging in the direct top centre of my 1.5m high 1.2m x 60 grow tent?

Should I keep it very far away from my plants to receive any benefit, if there is any from that disc of garbage?

I am alternatively and readily planning on using an already purchased 135 w dual spectrum CFL, the 2700/6500 I believe, didn't go 300 because I was concerned over heat..

Also with two more supplementing (x2 135w Studio photography bulbs 5000k) - I also bought these impulsively, so please someone tell me if these:


Ebay this - 2PCS 135W 5500K 220V E27 Photography Daylight Photo Video Studio Lamp Bulb



Are these usable or just wrong for MJ?? Or will they cover sides nicely below my possible disc/150w Dual spec CFL?? I'm very excited to find out.. SO

How should I use these lights effectively?

I assume 8000+3000+3000+120(disclol) lumos? "Ish"

Will I encounter heat from these three CFL's mentioned? I'm sure the UFO knock off will run a little or alot of heat too?

Any experience with any of these bits would be fantastic.. Someone please solve the age old UFO mystery - do they harm your sht or do they help and what can one 150w /True 38w dual spectrum grow? I dare someone to find out..

Will CFL's alone give me top head?

Oh and also, dont turn this into a HID thread, obviously HID's are worse than my Chinese UFO disc because they're expensive to run and a fucking fire hazard and undoubtedly causes insect death on a mass scale

I've just tried a 150w chinese UFO on a small scrog box as an experiment and didn't expect much. I was surprised when I cropped 2oz dry from a 12" x 24" net. The UFO cost £35 from Amazon. Good for small cabs/boxes but doubt they will be any good for a tent. 300w CFLs kick out some heat, be careful.

 

[tacobean]

Did you use it from seed to flower? any supplementing light?

Did you notice anything unhealthy about the plant during its growth phases?

Thanks for your reply KrazyG, Cant find any reliable info on these cheap things and to be honest..

150w cfl Dual Spectrum + x2 130w 5000k (anything wrong with this spectrum) Photography CFL's should do the trick right?

All i'm trying to figure out is if the LED UFO chinese light is going to damage my grow whilst the CFL group I have could grow just fine..

Do I risk it? Can it be harmful? Will it stunt growth?

Is there such thing as an early flowering or cell deformation from such conflicting spectrums?

 

[KrazyG]

The only problem I had with the UFO was a bit of UV bleaching on a single leaf caused by the light been to close. I used this from start to finish, I was impressed with the result, had denser buds than my CFL grow. As for CFLs 5000k won't be much good. 6400k for veg and 2700k for flower. I use a 300w dual CFL just for ease of use, ain't got space for loads of bulbs but I struggle with temps on hot days. I yeilded 4oz dry from the CFL in a 20"x20"x70" cab. Small££££. Lots

 

[tacobean]

Good stuff! did you need to vent that 300w? I deliberately bought a 135w because I thought it'd be too hot.

All my 135s are true 135w correct? so I'll have UFO 38w+135x3 = 443w, theoretically should beat your 300w in yeild

Could I have more than 2 plants below such coverage?

The 300 needs venting it chucks out quite a lot of heat in a small space. I run pc fans for intake an extraction, they cope pretty well unless outside temps go above 21°c then I struggle, but I solve this by putting a desk fan next to the intake. I can't do much about it I need to keep it Stealth. You could put 3 plants in easy and LST. My first grow had 3 plants in my cab and yeilded the same as 1 plant, they will grow to what the environment allows. Good air exchange is vital. The thing I found with the UFO is it doesn't have very good penetration that's why I did the scrog all the bud is a flat surface so light penetration didn't matter.

and call it a day. The Timber setup is the better value of the 2 lights that I linked to, but it's a few bucks more.

@KrazyG - How far did you have that UFO from the top of your plants to give them leaf burn?? did you use it from seed?

Okay so I now have: (do infront of links if can be bothered to look at my CFL globes)

x1 2700k 135watts
x2 5500k 135watts
x1 2700k/6500k 135watts

I have those four lights now, all on their way.

Is my spectrum good with these for two plants?

Do the 5500's still perform almost aswell as that 6500 in terms of plant response to the blue or did I waste money?

Should I only use the 2700k in flowering or should I add that 2700k 135w to the 5500 pair and the dual spectrum the entire way through?

More watts more lumos right so yes? but will it induce premature flowering having that 2700k on during veg??

Thats a total of 540? watts all together right? 6000 lumens each = 24,000 lumens

Will My Plants Thrive??

Also.. i'll have a little UFO 38w full spectrum above all these cfls..

Whats everyone think? am I good to go??

And should I put the entire light system i've just mentioned over the seed when it first sprouts or is that too much?

If anyone can answer most of my questions here or in PM i'll send you a free 130w bulb!

 

[Johnny Lawrence]

smh.

@KrazyG - How far did you have that UFO from the top of your plants to give them leaf burn?? did you use it from seed?

I had it about 6" away that caused burn, I keep it around 12" away now with no problems. I used CFL (23w) for the seedlings for 2wk after sprouting then switched to UFO. You don't need to much light for seedlings, like I said a 23w 6500 worked fine, all your bulbs is overkill for seedlings and a waste of electricity. I think putting the UFO above the CFL's is pointless I think the CFL's will filter the UFO??

 

[tacobean]

It does? First i'm reading about this, I hope the Mylar reflection in my tent will ensure some LED absorption.

Just had the UFO light arrive tonight, took atleast three seconds to turn on properly from a dimmed state, first time its been turned on im guessing and I was nearly blinded.

Thanks Krazy, Smd Johnny.

Krazy are you saying 23w (low light very low light) to begin with is appropriate?

Can I not pump 550w of LED and CFL into my sproutling straight away?

 

[Johnny Lawrence]

It

Yes.

 

[KrazyG]

This worked fine for me. I personally think 500w for a seedling is ott.

 

[Psyphish]

No such thing as too much light for a seedling, too much heat, maybe.

Do you think plants outside die immediately after being hit by sunlight?

Not saying too much but I personally think 500w is ott, you don't plug the sun into the mains, if less works fine u save £££

Overkill isn't beneficial either, but if you want to use one light source all the way through, you can. No need to start with a candle and work your way up to a LED panel.

Agreed. I use a small CFL for the first couple of weeks for seedlings then they move into the cab. Helps keep the electric bill down that is the only reason.

Not true, full sunlight can kill plants, start outdoors in a sheltered area and gradually move to full light.
