I really like the diamond as well, it's probably my best LED and it's why it's in this room, but I didnt try it on it's own, I just trust it!!. Don't forget that the frosty buds on the pics are also getting 760W HPS. I have a small plant under the blackstar 240 on day 4 flowering, looking forward to see how that one turns out because it's a clone from my healthy grapefruit. This plant will help me confirm my decision of not using the HIDs for the next run. If the grapefruit don't do well under the blackstar240 it will be hard not to use the HIDs because I will not be buying more lights, meaning the LED units I have will have to cut it. I figured once I have my flowering LEDs set in that room I will have roughly 450W actual draw LED to replace the 760W HPS... and it's goint to be hard to keep the lights at good distance because they all have very different specs!!

I'm using Bloombastic from Atami. If you use a finisher the last 3-4 weeks of your flower period, it induces what is almost like a "second flowering" and your buds continue to bulk up and harden. I suggest checking into either Bloombastic (which I prefer) or as an alternative Shooting Powder is pretty good. I prefer the Bloombastic because its organic so I use it a little longer than I would use the shooting powder. I usually flush for 1 week with using Bloombastic or 2 using Shooting Powder.

I'll definitely snap some shots of the 900 tent, but I have only used it for a veg light thus far so I am not sure how it does on flower. The 500w is holding its own thought so I think its kick some ass, especially 3.

nice what about with bio terra soil and bio nutes? whats a good bud finisher for those? 900 looks good for veg! I need to veg out 2 4x8 scrog what do you think would do it the fastest, 3 900 stationary, 1 1000 MH on a light rail, or i could do 900 on a light rail? what would you do?thanks

To come back to the UV ray discussion, I cannot say whether the reptile lamp or the diamond 100W or the strain is responsible for it, but my Afghan Kush, which is the plant in my scrog that gets the most UV and the most LED light, has the smallest buds bud damn they are frosty, the pictures are a couple days ago and it seems like its getting frostier by the day. Personally, I had to deal with the heat when I first installed my 2 400W, adding the reptile lamp made no difference on the room temps, definitely too hot for a grow cab though. Next grow I will not use the HIDs in the room so I am looking forward to see how the LEDs will do with the kick of the reptile lamp.

I would be very very interested to see 2 grows one with just led and one with led + UV. No HPS involved. Now that would be good research !

Mind posting some pics with just diamond grow? Do you have a connection with them, on there prices cause for 1995.00 I can get 2 9000 watt black stars. How would the 800 compare to one 900 BS?

Those are just crazy expensive to me, 800 for a 300 watt is insane. The diamond lights would have to give me head while growing to validate the extra expense over the blackstars.

I'd say go with Bloombastic, but you want to add it immediately if your plants are around day 30ish and slowing. I have no experience in flowering with the 900, or MH, so I would not be a good person to ask on this. Anyone with any experience with 900w Blackstars and MH on this thread that can help answer?

I don't have any pics right now of just a diamond grow. I'll shoot you a link to some journals on another forum that have plenty of pics and info on the advanced led diamond series. I do get a discount on them because when I preordered mine back in August, they locked me into the promo price for future purchases. I've never used a blackstar and from what I see they do a great job for the price. My concern with blackstars is the build quality of the unit itself and the warranty. The advanced leds are built very well, you can tell it's a quality product just from looking at it and picking it up. I do know that blackstars are not pulling the actual draw that they are advertising so that 900 is probably more like a 500w but I'm sure Wejauana or a saavy blackstar user here can confirm that for us. Either way, I expect an 800w diamond to perform better than a 900w bs. Again, I've never used a blackstar led and am only basing this on what I've seen and heard about them in comparison to my own experiences with advanced.

The DS 300 from advanced actual power draw is 275watts. I have 2 of the 500watt blackstars and on my watt meter they actually draw 280watts so the blackstars come in at $549 and the advanced DS300 is $795. I know that I would never buy another Blackstar because the build quality is absolutely diabolical with a flat aluminium plate and very bad chinese led's that just dont do the job properly. The cooling fans are probably the noisiest and the cheapest they could lay their hands on. I know I sound angry but it was my own fault for buying cheap. You get what you pay for ! IMO,,,at this moment in time it would seem to me that the Advanced led's seem to be good value for money considering their build quality and specs, their only fault is that they have switchable spectrums for veg and bloom which to me is a waste of half a light. I want a FULL 275 watts of veg or flower power raining down on my girls, any thoughts ?

Yeah the Blackstar 900w unit pulls around 520w on average.

I was told the blackstars have usa diodes not chinese thats why I bought them. I would have to agree about the 800 but at the same time to run both veg/bloom at the sam time while flowering or vegging is prob beneficial cause during flowering Ive read its best to mix MH and HPS to throw all spectrums around.

I thought the blackstars were labeled for their true watts

Edit: I guess I was thinking of a different light!
