Mythbusters showed plants preferred loud music and sounds in a controlled test: Mythbusters - Talking to plants - part2 - YouTube
I'm using MH lights bare bulb and get UV that way. MH in veg after a few weeks under 6500k T5s and 1:1 MH/HPS in flower. LOVE the results and...
I'd say the other way around. It should be like increasing voltage. 240 volts runs cooler amperage wise than 120 volts. "A neat analogy to help...
Well if you use a digital timer to turn on a relay you should be OK, that's why I love DX Hydro. :D
LOL, one neighbor thought he was a vampire. Yeah, a vampire w/no brain!
Just topping off w/RO water or just adding same nute ratio to top between res changes and not checking pH or EC would be lazy, yes.
Flushing's in Queens, NY - also for toilets. ;) Curing or decarbing non flushed plants is a lot better. I do a res change once/week and I think...
Digital timers to operate lights are mainly asking for trouble unless you use them to activate a relay. They run pretty warm just displaying the time.
Yeah Titan's quality though. You get what you pay for and it'll pay for itself in no time. Guess it's the Ron Paul of timers, will work well but...
Wow, maybe Oracle was looking at a chart like this: [IMG] It says 252F for 27 minutes. At 223F curves still rising after 50 minutes. This is...
I was just going to ask same question as Lothar. Since proof is in the pudding, I think Oracle's w/o dessert! :D
I wish Nikola Tesla was still alive and they tried to install a smart meter on his house. ZAPPED into oblivion! :D
Cfls are inefficient (about 60 lumens/watt) compared to t5s and pll fluorescents (87-93 lumens/watt). Plls look like a folded t5 tube. Also you'd...
Ditto Jeremy, GH & Dyna-Gro rock. Maybe I should have said 55 watts/sf with a glass on reflector. But yeah, over 50 wattss/sf you basically get...
Ideally for 4-600 watt hps lights @ 60 w/sf you'd want a 40 sq ft room. That takes into account the 10% light loss from the reflector hood glass...
Some more research (page 61 shows world map UV doses throughout the year): P. Ciren, Z. Li / Agricultural and Forest Meteorology 120 (2003)...
Real interesting thread! I heard someone mention @ another forum (Fulvic) "Like I said, I've tried many different methods and nothing has come...
I mostly disagree with that. Even Michael himself says "practice makes perfect". He was cut from his hs basketball team btw. Same case w/me: I put...
T5s and PL-L fluoros are about 25% more efficient than 26 watt cfls.
Hydrofarm Active Air and C.A.P. Valuline are both good and can't go wrong w/either. I'm getting 3 8"ers myself - I pick the Valuline. It does run...
