    My autoflower likes 100w vs 400w

    What’s up my fellow growers, hope everyone is having a blessed day. I’m currently growing a NL auto, she’s about 33 days old, and she absolutely hated my 400w LED. I have another 110w led I use for my babies before transitioning to the larger tent, and she prefers this light over the larger one...

My plan was to run 9 to have 1 light every sq ft but Im having trouble finding a driver that would run all 9 COBs in series. Would I be better off doing 5 COBs on 1 driver, and 4...

    Rapid LED. Am I right or wrong? COB pros, chime in please.

    So I ordered the 4x4 kit from Rapid LED that comes with 12 Cree CXB3590 COBs and 3 drivers run at 1400ma (50w). Then they released the 5x5 kit while my order was still processing that runs the Cobs higher at 2100ma (75w). So in my ignorance thinking more watts equals the more bud I will get, I...

    Power/watt useage concerns

    hey RIU community. Got some questions concerning my useage of power on my first grow.

    Heatsink USA Calculator

    Hey RIU, I stole Supra's HSUSA table format and made it a bit... sexier. Also, added some functionality to help those of us that use this style of heat sink. This calculator should help you decide what profile to pick if you are considering this route. I'm no expert, and I would love someone...

    LED - 1w Diodes vs 3w/5w Penetration Distance Above Canopy?

    I have been interested in this question I've been wondering for a while and I feel the need to post this and ask for opinions, but I have a 1000w LED light running with 200-1W diodes. (On a side note, I assume that means I'm really running around a true value of 200W). Even though there is no...

    Watts per Square Foot Explain?

    Can somebody explain the watts/sqft number people are using on these forums? Or point me in the right direction for the answer? I see many people saying 35-40 watts/sqft is optimal, but what's the math/science behind that? Wouldn't something like that only be reliable if you are standardizing...

    What wattage do the drivers (and fans) draw by itself?

    I calculated roughly 1W per fan for my fans which are Arctic F12, based on [email protected] (see their specs). Then there is the Meanwell LED driver, say some typical driver like the 1400mA or the 1750mA drivers, and the 12V MW driver for the fans. Just wanting to know when I measure the TOTAL...

    Update on my Tent - Flowering in Progress

    These lovely ladies were turned over to 12/12 on 4/5/16. This means we're twenty days into flowering and I think looking pretty good. It's a little crowded so I did just enough light pruning in to let light get to the lower branches easily. I think they are looking pretty healthy. The two big...
