What HID reflectors do you use and why?
I know there are other good options, but if you only need 4" or no air-cooling, i keep coming back to the Super Sun original. I have tried Maybe 7or 8 others. The super sun original (there is a super sun 2 which i dont like as much, but it does have 6" air-cooled fittings) is extremely small and lightweight, while sending out a fairly even footprint for all size bulbs. I have used 400, 600, and 1000W in this reflector. This reflector would be good for supplemental light in a GH since it is so small it would creating little shading of natural light during the day. The only downside is it only has 4" air-cooled fittings. I ahev tried 6" and 8" air-cooled reflectors such as Cool Sun XL 8" and the Yield Master 6" and have noticed a poor light footprint (uneven) and a lot of light being lost through the holes for the ducting. The Super Sun OG has reflective covers over the air-cooled ports so that no light is lost down the air cooled ducting. I will search for an extremely in-depth post from another forum that has people taking a light meter every square inch w/ different reflectors and data logging it. If i remember correctly i think the Super Sun OG was one of the better ones (least hot spots, most even footprint). I look for that info.
I think growit has some pictures of his plants in his photo section and there are some pictures of the basil there ... looks pretty good, but I don't know if that is the final harvest height or not.
Have you started your first grow with your indoor system AJ? The manufacture of the LED lights I am looking at suggests supplementing the lights with 400w HID for a 4'x4' area where there is high fruiting plants being grown for up to an hour each three hours.
I tried to track down the source of the bulb not lasting as long and I could only find this statement on someone who made a dyi light rotator out of a ceiling fan. So the speeds most rail systems go at it should be fine, which is promising.
I am wiring up LED lights to supplement the HID light to be used like this
I might end up making a cylinder style layout of Zipgrow towers with the light source in the center but I haven't decided fully on what I want to do with the growing area. This would make it posible to have a single HID in the center on a counter weighted pulley system. :-D
Hey, any updates on the comparison between the 400 and 1000 on the 4x8 space.
I am about 2-3 weeks out from my lighting purchase, so am interested in your results.
Loving all the pics you put up.
Found these guys randomly but they sell everything
Prices used for the following products
PX-LU400 Plantmax 400W. HPS High Output 50,000 lumens $29.95
UGRCT8 8 in. Cool Tube with external / internal reflector socket with 15 ft cord - 24 in. long $149.95
QD400W Quantum 400 Watt Dimmable Digital Ballast $189.36
QD600W Quantum 600 Watt Dimmable Electronic Ballast $204.75
400w = $369.26 x 2 = $738.52
600w bal. @ 300/450/600w = $384.65 x 2 = $769.3 (+$30.78 difference or +$66.02 if you go with 600w bulbs ($806 total))
LR3.5ID6-kit Light Rail 3.5 6 rpm All in 1 Box - Distributor Pack - Rail & Motor $229.95
LR3AL-SYS 6 ft add-a-lamp pkg. Includes rail pushrod trolley & hardware $59.95
400w + Rail = $369.26 + $229.95 = $599.21 ($139.31 difference vs 2 400w only)
400w x 2 + Rail + "add-a-lamp" = $738.52 + $229.95 + $59.95 = 1028.42 (-$289.9 difference vs 2 400w only OR -$259.12 for 600w bal. @ 300w OR -$223.1 if running 600w @ 300/450/600w w/ 600w bulb)
Note: Did not use 600w bulbs in the calculation for the "upgrade" to 600w, however this ballast is dimmable down to 50% original power (300w) hence it was chosen with the option to "upgrade" in the future, and it was only $16 more.
Also the 8" tube was chosen over the 6" with the idea of upgrading if need be in the future as well as it was only $10 more.
Also obviously this isn't the cheapest place to get bulbs >.< the 600w bulb price above was from another site ($47.96ea) and they sell the 400w cheaper too at like $18 so savings is relevant.
That stated, buying two 400w or 600wbal running at 300w seems to be the way to go if you have the cash for it right now.
In the log run it's probably best to go the 600w with dimmable ballast route than to go 400w this way if you ever expand you can do so easily without purchasing new equipment, and in the mean time you can run your 600w bulbs at 300w / 450w / 600w as you see fit.
But it all comes down to cost, $806 is the entry for the high level, $738 for mid level, and $599.21 low end w rail.
I have already spent $757 on LED's to wire up ... I have no purchased my two 400 / 600 support ballast / reflectors running 4 hours a day. Savings on electricity will be $375.84 a year versus running the 400w every day 16 hours a day >.br/>
So the LED's will pay themselves off in two years on savings then another 2.5 years to pay off the other lights (with energy savings alone of course.)
Was this the "other forum" you were thinking about in your original post?
Just ordered two Quantom 600w dim ballast today >.< $334.85 shipped
Yeah, that was the link. Thanks. I beleive they were saying the super suns and the XXL's were the best. Its a lot of info to go through.
Nice deal on the Quantoms; what bulbs and reflectors you getting?
