Personally, I don't want to be on the "bleeding edge" -- too expensive.I no led saves money and cooler grow rooms but is it worth paying 5 times the amount for a light
All stick with my hid untill they break and still proably buy more hpsPersonally, I don't want to be on the "bleeding edge" -- too expensive.
I recently bought a 600w Lumatek digital ballast on CraigsList for $50. Practically brand new & works like a charm.
If you're buying all new gear, then LED is worth a look. But if you don't mind running used hardware, there are some serious bargains out there. The best time to buy is right after Christmas. People dump their old gear crazy cheap.
I've never needed AC -- even during summer months. Run the lights at night with a fresh air intake, then vent outside. The temp of the air going in is what matters most.I think a lot depends on how much you spend on AC for hids i think... i have a 600 and i need to worry about HEATING things right now... lol
Ouch! That's a lot of paper.I think if you go with a led you have to buy a very good one. But they are around $5000 each over here. So I just went with 6 gavitas and master controller at $820 each light. I never use a ac to just fans
Yes lots of paper but with great resalts. I have only had 2 grows with them. First one was a bit of a rush job and pulled 11.2. After a bit of fine turning the next grow went 13.7 lbs that's with 6 plantsOuch! That's a lot of paper.
I paid $70 total for my last rig. $50 Lumatek ballast (600w) + $20 for a light & reflector. (CraigsList)
LED is getting cheaper overall. I recently upgraded a bunch of old incandescent bulbs in the house. 65 watt bulbs now only draw 12 watts, but best of all, the cost has gone from $24 to $5. The same thing will happen with COBs -- that's when I'll upgrade to 100% LED.
5 years warrantied for my Johnson grow lights I believe. It's "projected" to work for around 10+ years without much degradation in spectrum emitted to my knowledge. I don't veg with them; only for a few days before I flip them to flowa. I don't see an advantage to using them for veg; other than you will not need to hang a different light for flower vs using t5 for veg and led for flower to extend the lights life span.How often do cobs need to be replaced? if used every day 24 /7
I've gotten 1.5 grams per watt with my setup. I bet you will like the results from the Johnsons rig. How far are you keeping the light from the canopy?I just got some cobs from Johnson grow lights. I like how the plants look. They are strong; I usually run 1k digital ballasts. This is the test run on the cobs; and it burned my plants at a farther distance than my 1k usually sits. I'm hoping this thing produces. It was not cheap like everyone says but after shopping I can say the price is fair or on the lower side for the quality of the light. Split the cost by the 5 year warranty minus the savings in electricity and it's still not cheap. But if it yieldslike it is supposed to then I think it's worth it. I will know in about 7 more weeks.
Solid bro, what strain?300w of Cree COB 3590's ran @2.1a net 320g dry weight frosty sticky nugs
