brilliant plant bro interested to hear what the dry weight was could you give a little more information on what light you exactly used for that plant , nutrients, and about how far you had it hanging from the top of the plant?

If it's me you are replying to ... thanks, she was a nice plant.

Well she was four plants (clones) growing in the one large hempy pot.
The screen is about 2 foot diameter and is attached to the pot.
I use 3 parts perlite and 1 part vermiculite.

Nutes :-)

the cheapest, crappiest, supermarket quality general purpose fertilizer sold for Mr & Mrs Suburbia to feed their house plants ... and a similar quality "Bloom Booster".
My 2 boxes of "nutes" cost about $12.00 in total and will grow maybe 50 of those grows.

My vegging/cloning/grafting area uses Kessil H150 Purple lights and I flower using the Kessil H150 Magenta lights (one light per 2 foot dia screen)

Lights are hung 40cm above the canopy for both vegging and flowering.

When dried to 65% humidity the manicured buds weighed 40.5g which is 1.125g/watt as the light only draws 36 watts.

40g is not a lot of weight but the quality is excellent and is more than I need, and I get a similar amount of a different strain each 5 weeks (based on 10 week flowering strains).

That is definitely a good LED grow. One of the better ones I've seen.

How much extra do you think you would've yielded if you used top of the line nutes, and one of the highest yielding strains?

I just bought 2 Blackstar LEDs, I'd be pretty happy if I got results like you got. Of even .7 grams per watt for that matter would be nice.

Wow awesome man yeah 40.5 grams for 36 watts is amazing do you plan on upgrading your set up at all maybe going more wide spread now that you have seen such great results? interested to see future projects from you
 
So tempted to say fuck it and grab a SG 602 for my first grow vs a 600w hps...lol

My more realistic plan is to grow with hps for at least a year or so before experimenting with LED's but the decreased fire hazard, heat signature, and energy consumption sure is attractive..

Hehe, if you can afford ~$1500 for 350W from the SG302, you may consider jumping on the Blackstar band wagon and getting 6 of them shipped for that price, which would give you ~720W of LED. Your 600W HPS uses close to 700 /w ballast. 5 Blackstar would be right at 600W, though. You won't look back though, from the heat to power savings, life is better with LED. I'm still using both though, until I can replace the 600 :)

Or you could go with a proven panel company like GLH or Magnum/ISIS. More expensive than Blackstar but cheaper than that SG

I'd be hesitant on Blackstar as I've seen mixed reviews on them. I would think just dropping in a bunch of them would be easy enough, but fewer (more quality) units would probably be better, no? The price at $250 or so is nice though haha. The 357's are appealing since Irish Guy was able to coax about a lb from two of them I believe. But then I'm back to $1500, which isn't going to sink me financially but it would put a lot of pressure on me to have a successful grow right off of the bat. I know he did well with the GLH line but their site is all janky (right now anyway) so I'm hesitant to go that route.

Still a noob with the LED research (and in general) but they certainly have some great things going for them. I'd like to drop an SG 602, 2 357's and some GLH's all in a 4x4 or so and see what happens. :D

Also, what kind of exhaust fans are you running with LED's? I'll have around a 4x4 tent. I'm sure you need less than with an HID, just enough to pull through the C filter and circulate the air every 5 mins or so.

Check out advancedledlights.com. I'm rockin the 3w 180w extreme flower in a small closet grow and the results are awesome. Grab a couple of those or their larger models and you and your plants will be happy in a 4x4 space. Hope that helps some!
 
Question for you LED'ers. How do you keep it warm enough in your grow areas? If I were to drop a SG 602 or 2 357's in a 4x4x7 room I doubt it would kick the temp up to where I need it. My space is in the basement, partially underground so it stays 50-65 down there all year. I imagine you supplement with a space heater. But then, is it really all that more efficient? I suppose having a well insulated (drywalled) room would help, but you're still exhausting/intaking fresh air. I don't really want to set my two 1000w in wall heaters to 75 or so and heat the entire 700 sq ft room while my grow room is only 16 sq ft..lol

@ puffenuf: I haven't heard of those, I'll have to look into them

Edit - Just searched this thread and saw this topic was discussed before (imagine that!). Anyway, it looks like you just have to use a space heater in the room. Any recommendations there? Safety first for me. I'd like to be able to go camping for a weekend and not come home to a pile of ash. Pretty sure even my legal grow as the source would void my insurance policy and I don't want to lose my equity...lol
 
I think if you insulate it really well you will be supprised I have a 6x7x12 room 2 BD220 and a 400w HPS cool tube and it will kick it up in the 90s with the filter and small intake it stays at 78 -- 82
R 19 walls cant remember the name but its mylar over small bubble wrap works great
 
I have 4 CFLs in addition to my UFO to keep the heat up. With summer on the way I'll probably trade out 2 of the CFL for a couple of LED spots.
 
Just put in an order for the Blackstar 240w as I couldn't afford the lights that I really wanted (GLH and Advanced). If all goes well with this light I'll save my beans up for a bigger panel. From what I've been reading here and on several other sites, the Blackstars do produce. If anyone is looking on eBay, the units can be haggled for just under $270 shipped. I'm only a State over so I should have it in a couple of days. Looking forward to putting my CMH to bed till Winter.
 
hi there.i am using an led black star 240 w......i must be about 4 wk to go.......what u think ? IMG_0424.jpg

They look fine under the 240 blackstar, it's a decent light for the money.

I like to think its the best LED for less than $300 (some can get it as low as $250), and also the only unit for less than $2 per watt that works good (the best cost just under $3 per watt)
