Hey DesertHydro so your cobs are wired in parallel right?

A 1000w hps will make more heat then 1000w cod led. Yes 1000w is a 1000w. Hps super heats a gas to make light creating more heat. LEDs do not.

For that price I'd rather get 4 timber or cutter kits.

What sweetner would you recommend?

Check out what I found once.

Legit !!! I really like my t-4 1750's.

Hey RM3 what is the best way to just add sulfur? Would micronized Sulfur work? Is that water soluble?Thanks man.

What's your pH after mixing nutes? Do those pots have drainage holes?

I just picked up a 3' reptisun 10.0 t5ho bulb and plan on running it for the last 10 to 14 days of flower. I'm going to put between my 2 tasty led t4's.

Your going to need sinks.

If you "do the math" the sun could be 93,000,000 miles away or 3000 depending on its size. The amazing thing is it would all work the same either way. You would never know unless somebody told you because all our senses lead us to the ladder.

I want to do this to my mars 2 700. Does anyone know the specs on the drivers they use? I pulled it apart and the drivers say nothing on them. I don't have a meter to take readings.

Thanks. I have mine mounted from the ceiling with bungie cords. I have a speed controller on it but when I turn it down I get a loud humming noise from the fan. I'm hoping since the hyper fans have been designed with a speed controller that it will not make that noise.

I'm looking at getting a new inline fan and was wondering how much louder an 8 inch is compared to a 6. I have decided to go with the hyper fan because I like the adjustable speed. Also are the stealth models worth the extra price? Thanks.

@bassman999 The A version of that driver would run at .700a or 1.4a. The B version with a100k pot could adjust between the min/max(not sure on the numbers) with out the pot it runs at 1.4a.

I went with the 10"x6" for my 3590's at 1.4a. I don't have them in my tent yet but last night I had it on for an hour in a room with little to none air movement I could but my hand on top of the sinkright above the cob for about 15 to 20 seconds before it got too hot. I but a small 80mm PC fan...

Thanks. What happens if you do short them?

@Growmau5 what if you don't have a 100k pot attached to a b type driver? do you have to short them for it to work?
