It goes into the difference between the units.

I have an original 200w. Not flowered under it, probably never will. Great veg light though I’d say it just about covers 1m2 for early veg stages, say 1st few pots. 

I just used it hung on tent frame in spare room, fan blowing at them and a window open.

 

solar powered on this pic so no extraction taxing 24:7 vs open tent worked wonders. 
 

been a bit of a learning curve with it. 
45-60cm a is great. And can’t believe how well it does say at 40%. For 1st 2-3 weeks of a grow. Crazy efficient tbf. 
 

Also had a mk1 maxi bright 660w,  they literally stretched through it touching the light and beyond on an untopped seed grow.  Design sucked on that vs these, bit no burn or bleaching.

@JeffLebowski the pro range has better outputs I believe just looking at the numbers. For the sake of 50 quid I’d go for the pro. I assume they’re more efficient if they pop out more light for the same amount of juice.

Thanks for the info. I’m in Ireland so can’t buy from Ledgrowlights. From other online stores on the continent the 300w non-pro is nearly 25% cheaper than the pro version. From the blog it says the pro version is 15-18% more ‘powerful’ so not justifying the extra premium.  Given my space is 70x70 (maybe can push it to 80x80) in theory i’m already up-sizing from the 200w which should cover the area. But again the price gap between the 200w and 300w is small enough that it makes sense to buy the 300w. 
I’m more curious what the ‘deep red’ LEDs do for the pro version vs non pro.

Can I ask why you wouldn’t flower under it? Color spectrum or intensity?

@JeffLebowski I believe…. The deep reds are the infrared (uv?) spectrums you get from natural sunlight or from a HPS bulb. The LEDs for whatever reason didn’t include as much of the red spectrum but looking at it it’s a thing that’s being addressed on newer units. You can get supplemental red light strips to address this but as an Attis 200 owner I can’t say it’s a problem. But being relatively new to growing I don’t have much experience of lighting with anything other than what I’m using now. 
I can only imagine @Budelaire wouldn’t flower under it due to footprint? I’m guessing there like. They are a small unit I use 2 in an 160x80 and it’s about right. I wouldnt flower using one in a bigger space. But aye, I’ve found consistently good for veg or flower and once it’s cranked up 100% temps are also fairly comfy, I find at least 26/27 even this time of year.

These are under those lickle Attis things. So definitely good for flowering but aye, you do right, size up for future proofing.

@mikeydoughnut those look like proper buds, congrats. 
I’m on my 1st grow. Have started them off with a cheap 100w QB for the first 4 weeks and have switched to HPS 400w since then. The plants like it but my temps have gone through the roof. Somebody warned me about putting a 400w HPS in a 70x70x140 tent but I didn’t listen. My extraction fan need to run at 80-100pct to keep temps down to ~25-26C which sucks all the humidity out so I’m at 40-45% RH which I don’t like. 

Read you comment on the Attis 200w running at 26-27 degrees. Imagine they’d still be quite a bit cooler than a 400w HPS?

 

[Budelaire]

Never really bought it for flowering that’s all. Was to bring seed on for the field mainly, I like them but would flower in a larger space so would need more and then I’d probably get a different style if buying multiples. 
 

They are great lights for sure, more of a case of never having had the chance or time to do anything with it.

Just to echo the variables in regards to different genetics respond to hanging heights.

 

I’ve had the 300w running at 240w, around 15cm from some of the tops as I’ve ran out of space. Had 0 issues compared to my previous attempts, some fox tailing but no burnt leaves or damaged trichs. 
 

I’ve just seen AC Infinity have a 300w fully dimmable unit in the works - IONGRID S33. Wonder how the price will compare to the Attis. Looks really nice.

Hi all, I’m on my second grow using an Attis 300. Last grow I only started using it at flowering stage so was 100% power and quite close to tops from day 1. 
I’m on week 4 of growing 3 autos in my 60x60 tent and have the lights at 80% power and about 50cm height. Is this too much? 1 of the plants is showing some signs of stress (but also had fungus gnats on it). The other 2 look healthy but have remained short and really bushy which I’ve read could be a sign of too much light. 
any suggestions from those who have done full grows would be appreciated.

@JeffLebowski I don’t understand autoflowering plants like. But you mean 4 weeks from seed? 240w does seem a little excessive at this stage. Turn it down n save yer sen some lecky  …. I veg under 2 Attis 200’s. They’re on 120w each. Everything is plodding along fine. That’s with 4 plants ready to go into flower and they’re fine despite their maturity. 

Cheers @mikeydoughnut yes 23 days since they popped out of the ground. They’re still in full vegetation phase but will likely switch to early flower in the next week or so. Will try lowering the intensity to 60%. Is the height ok at 50cm from canopy?

[Smokey McBongface]

If you work up in stages it can be a bit more forgiving but I’ve found if the top of the plant is stressed the middle to low tends to thrive. The light penetration of the 300w through a canopy isn’t great, so the closer you can keep it the better. As long as the tops don’t suffer too much you’ll be fine.
 

Some strains can take the extra light without issue, others not so much.

@JeffLebowski my first grow with the 300w, I only took it up to 80% at a height of 30cm from the canopy, in a 70x70 tent. Things turned out very well. Not a hint of any problems with the buds, and the smoke came out really nice. 

My second grow under the same light and I cranked it up to 100%, that was a big mistake, as I burnt quite a few buds. Although admittedly, some of the burnt buds did get real close to the led, even after super cropping. I didn’t end up smoking any from this grow, I just stripped the plants for edibles.
 

Now on my third run with this light, and I’ll be keeping it at  80% or below from now on. It’s more than enough for such a small space. The plants look like they’re loving it, and the temps are quite a bit easier to manage without that extra heat output.  
 

The plants are currently in their first week of flower, light set at 60% and everything looks good. I’ll crank it up to 80% at about 3 weeks in to flower and with the outside temps falling, the extra output should help increase the temperature inside the tent.
Well that’s the plan anyway. 
 

Good luck finding your sweet spot.

@four2 @Smokey McBongface cheers for the feedback and advice. I’ve dialed it down to 60% and am at 48-50cm from canopy. I’ll see how they react to that. 

@mikeydoughnut

One of the plants showing pre-flowers so reluctant to go down to 40% now but I’ll see how they react over the next 4-5 days and adjust from there 

Some of the new growth showing some light green/yellowish tint at the tips could be a sign of light stress? Temps are under control at 22-23 max and 20min 

 

 

these are the (what look like) pre flowers?

 

 

apols don’t want to turn this into the ‘diagnose my sick plant’ thread but might help in a dialing in the lights right 

[Harry Herb]

I'm having headroom problems this grow.  The stretch is finally over and the tops are 20cm from my Attis 200w, which is at full power and can't be moved any higher.  

 

Anyone have a view if this is too close for that much light?

 

Previous grows have been fine at 30cm full power all through flower but this feels too close.  No signs of burning yet at almost 5 weeks into flowering.

Heavily supercrop with support, and you probably wouldn’t see any evidence of burning immediately, unless touching the light, it will develop over time, always better to deal with it before it’s a problem. The leaf efficiency is already compromised if they’re that close. Which could contribute to growth/yield loss, poor plant health and susceptibility to disease.

What's the optimal size tent for the lumatek Attis 300w 90cm or 1m?

 

Currently have the 200w in a 60x70 space running @120w last run hit 1.5 Gpw but looking to upgrade. I guess I could put that into an 80cm tent but will probs just want to upgrade straight away so may as well do them both
