gobbly, If it's 150w and they were using 3w LEDs my light is equivalent to theres. Question is, is it more effective ;) I really dont have the funds to explore cree modules and actually find it very difficult to establish what wavelengths they sell. The main site does not respond to emails and...

MellowHaze, I am giving my light away :P the other half doesnt want me to explore LED technologies with my favourite plant anymore so i'm back to tomatos and herbs. :P I will provide information for FREE! for people to build there own lights. Just pick my brains. have fun ya'll

total cost has been roughly $175 US. I have a supplier in hong kong, i posed as a panel builder "trialling" their LEDs in comparison to Cree's (which is not exactly true) the LEDs are good to say the least. The controllers are a bit harder to find. I would suggest finding someone who will do...

I'm using sealand opto electronics. I have told them I run a business manufacturing LED panels and they sell me the LEDs at factory price. I would suggest hopping on their website http://www.ecvv.com/company/sealanddora/index.html an sending them a message. they are in hong kong but reliable...

purextrato, look at my link. I will send info if you need it. just ask me lots of questions, I prefer it this way :D

Ok guys, Heres the update. I cannot finish the grow period unfortunately I have to move :D It seems impractical for me to drive her 8 hours. So she is getting passed on to someone else to look after her. 108kW hours used so far. I'll post a photo in 3 weeks time, on the last day. I am also...

rowlman and wil, You are both asking the same questions, the short answer is. you are charged based on kW hours used. so... a simple mathematical equation is needed. Assuming a fixed tariff of 0.13c per kW hour. lighting: 4 x 400w = 1600w timer: 16 hours on first convert the wattage to kw...

As i'm sure any mother/father on this forum will tell you, they always know their children. I would certainly know if my son smoked ;) - but thats my two cents. Also, consider that your parents may be questioned and made accountable for your actions as it is "their" house, not yours. and...

Total, In response to your last post: I wouldnt be too concerned honestly, you'd be surprised how efficient AC power is. I have had issues with my LED light firing up all the LEDs at 1 time (which is DC) until I added a current controlled "soft start" to the controllers. Fluoros have a...

Total, that depends. Do you need multiple timers running that switch on or off at random intervals from eachother? Are you exceeding the maximum wattage rating of the timer? If you answered NO to the above questions then I would suggest using the 1 timer, I know people will say "dont put all...

This is very true, high wattage lights run awfully close to a dead short with only a very small resistive load on the ballast. change breakers :)

Rocky mountain high, typically most devices have a mains fuse prior to any other component. I would suggest checking that fuse first, it fixes problems 95% of the time. Alternatively; if the fuse is ok, I suggest looking for a square shaped component or 4 diodes wired in series back on itself...

blue berry, french vanilla and tequila are nice.

In other words.. no, dont exceed your breaker. I would however suggest replacing 1 of your MH's with a HPS IMO ;)

Although 240/120V AC fans flow more I prefer 12V fans, they are safer to use, setup and safer to adjust the flow of. using AC speed controllers that regulate voltage or resist current can cause fires. The only correct way to dim AC fans is via PWM (Pulse Width Modulation) For that matter if...

Thanks guys, I am picking up my chassis today for my 300w version. I am introducing 6 x 420nm UV and a mix of 6 x warm white (3200K) and 6 x neutral white (5000K) Hopefully my next gen light will induce flowering a tad faster. The female preflowers seemed alot smaller than images i've seen of...

mmm.. I dont think thats safe. if people are aware of a giant plant growing in an old warehouse at ambient minerals they will probably want a piece, know what I mean ;) This could jeopardize your 215 license. I think it's a sham, but i would LOVE to be proven wrong :)

lol.. throw some LEDs for good measure :P you better deliver.. I am keen to see!

Ok, 13 days into flowering total power consuption is 91.3kWH heres the pics. *Please note the cfl is only being used for illumination 2 minutes prior to the beginning of the photo period for photos. I do want to make this an experiment still :P

hmm... It is ok to hand solder luxeons or CREE's, I have done it for my 3w LEDs on my home made panel. this is simply a recommendation and certainly not critical to the life of the LED. The LED modules themselves are actually very tolerant to heat and static tolerating up to 40kV static surges...
