Interested in this too. How does it compare to same conditions but with HPS?

Missed this question earlier. I used to run 3x600HPS over a 4x8 table so pretty familiar with 600's performance. At this point they are flowering as well as I recall under 600's with the only difference being that I really don't think this strain is that heavy a producer. Not trying to make excuses for the LED's, I just had a buddy who's a seasoned grower who is consistently a 1.75-1.8 lb per light grower pull down 1 lb 5oz of this strain and itn't going to run it again. We both run coco and CO2 so it's a pretty good heads up comparison.
That being said I'm gonna run the wheels off this grow and see how I do against his 1lb5oz under 1000HPS and that should give me a good idea of how these lights perform. Condisdering my actual draw with both lights is only 360watts if I come anywhere close I'll be doing really well.

morning all. yum yum looking good. couple questions how much co2 you say you giving them? and you say you just started with it?
you just doing the normal nutes (GH)? also do you think that the results wood be same if you was running your flood and drain tables rather then hand feeding them?

They've been getting CO2 from the beginning of flower. Controller is set at 1100ppm and it's a propane burner supplying. Once in a while the propane runs out but I usually catch it within a day. Nutes started out as regular GH but switched to their Flora Nova series about three weeks in and running carb load as of a week ago although should have been running it sooner. I'm gonna rig up the system when I have time to take advantage of the flood and drain tables and just feed them on a bottom soak system just like flood and drain. I don't think it will make much difference, just easier.

if you did run the table again {flood n drain) wood you stick with the same pot mix(coco , perlite and small amount compost) or wood you change things about?
how are the nugets doing on the lower branchs? look good on pics but cant c if they gunna be thick hard buds or whispy? sure over this week will see more.
oh and not sure if you seen the black dog led panels. think the platinum model has 3 and 5 wat leds? anybody out there got one yet or no of any journals using them?

Im sure you would be getting crazy light penetration with those 5watts. whats the total wattage and price of the units?

they sound good but cant find much info on the company. i beleive it is 740 actual watts and 288 leds. but wot make of leds i cant find. check out black dog led. think the one i talking bout is xl plat model. think it is 1600 dollars. they have a 300 w panel also for 600 dollars using 3 w chips. wot i like bout this company is all lights can be set up for just flowering or veg or available in full cycle. thinking that if they do work well and got one for just flowering, i can imagine or hope the penetration wood be so good that side lighting could be a thing off the past... or mayb just wishful thinkin

Only "grow" I can find with Blackdog LED is by ebflow. Seems like it could be by a company rep though and no updates in a couple of weeks... Anybody else see BD LED in action?

nice lookin grow dunit. nice to see people having success with led they sure have come a long way. I'm new to RIU but not to growing MJ. This summer I will be expanding my small closet grow into a full blown operation and was thinking about going LED and hydro or aero. I was looking into a 300W light from Growledhydro because Irishboy has had some amazing results with that manufacturer but the price tag is ungodly. I'm trying to cover a 6x3 foot area so if i bought one of the GLH lights I would have to put it on a 6ft mover to get the coverage I want SOG style. If I went with the magnum light I could buy 2 for the same price and put them side by side and get the same coverage. I could also save 700 bucks and buy 1 magnum and put it on a mover. I'm really just wondering how not having the light directly over the plant a few times a day would affect bud production. My walls will be lined with mylar also. I thank any educated replies ahead of time.

Lookin solid man! The Magnums are from the same parent company as ISIS right?

Yup. Grow Perfect is the parent company of both and they are out of Vancouver Island.

I only like light movers when they are used over a very short distance to help avoid shading of lower branches, basically moving the light inside the normal coverage area of a single light. Anytime you use one over a large area to replace another light you basically reduce your intensity for the duration of the light cycle. Because LED's dont have the footprint of big HPS lights I'd be inclined to avoid light movers but thats just me.
Irish did well and was certainly one of the pioneers of LED growing and his journals convinced me to give them a try again after my Procyon experience. LedBudGuy is doing better and watching his grow, and using an ISIS for veg was how I decided to go with Magnum as they are made by the same company as ISIS. The Spectra series are definately one of the good lights out there and my only beef with them is that the numbers on their web page don't add up. They say they draw a certain wattage and they also post how many amps they draw at 110V and the two numbers aren't even close. For example the Spectra 300 claims to draw 360 watts but the amps x volts adds up to 264 watts which makes them very expensive for that sort of output. I'm sure you'd be happy with either and in the end ignore the marketing and see who's getting results. My preference is two magnums and I was going to cover a 4x6 area with mine but this strain just never got as big as I thought so I'm under a smaller area.
