whats up ripper

I got that new 320w power supply for my growmax light :drool:

I started a grow with it and i will be doing a second grow with the other 240w growmax light :cheers:
Nice they talked about sending us some controller that allowed us to dim with our phones.. and maybe my power supply is in the mail. These lights are amazing

Small cobs
The fixtures run Samsung 301 B mid power chips - not a cob. These chips have been rated as highest luminous flux chip on the market - it equates in testing to 220 Lumens per watt - I use Lumens as it is easier to explain that luminous flux and with white light is a relevant number, although not definitive for horticulture lighting. We have found for running full cycles that 4000 K is by far the best white light spectrum available. If you veg / flower photos in different areas it is best to veg under 5000 K and flower under 3000 K - although we have professional grows that love the 4000 K as well for their veg areas, tends to grow a stronger "bushier" veg plant.

I don't wanna grow up I am a toys r us kid................... oh crap they are dead and gone. That is ok I still don't wanna grow up.

Cool lights. Do they have the spectrum, PPFD etc. somewhere?
Running 4000 K for these lights - We currently provide three different Spectra depending on grow - veg, full cycle or flower. I have our engineering team working on a bracket that would allow growers to mix channels of spectra but that is a few months away. We will of course run a test here on Autoflower.net for "proof of pudding". PPFD - we have not measured in a tent like this - but based upon our goniometer testing probable with this set up of 480 total watts and 6 channels it should be an average close to or exceeding 800, would drop to around 700 without the tent. Uniformity is extremely high across the canopy.
