Anyone else have one of these? I was pretty skeptical at first but the advanced scheduling that can be programmed is awesome. I have 6 steps (20 possible) throughout the 12 hour period that (I hope) closely resembles what my girls want to see. Does anyone have a spectrum recipe for these yet...

One of my buddies asked if I've ever seen or grown this strain. I assume the image has been altered. Anyone actually grown this rainbow monstrosity?

I received the Mammoth Microbes the other day and have decided to toss it into the experiment arena... I have a Strain Hunters "Money Maker" that I will be cloning and taking the 4 most viable clones for testing. 2 grow cabinets each with identical airflow, light intensity (same cobs, same...

I would like to add some "terpene enhancement" to my light bars. I just don't know what chips to get and how hard to run them. I'd rather not roast my ladies in an attempt at making them stronger. I'm sure some of you have learned the hard way. Any chance I can learn from your mistakes...

In my cabinets, I can't get an auto to pull more than about 2 ounces. Waste of space for me when I can get 3 times that from a photo. Are autos good outdoors? Or should I put them close to each other and burn through my auto seeds indoors? Autos never really impressed me. Especially not when...

I see that Bonza has a decent promo going, 75 bucks gets you 14 free seeds and 150 gets 28 free. Kinda waiting to order until I saw a great promo. Who's got it?

Will using a stake for artificial support allow a stem to grow weaker than if you left the plant unstaked and put a fan on it?

Digikey has the 18s in stock and ready to ship for 10.75, but I can't believe they are the cheapest. I'll be looking for about 25 of them if that makes a difference.

So, if I have an hlg120c1400a and I have 2 CXB3590s and a Vero 29 on it, nearly maxing the voltage, can I dim it to 50% and double the LEDs? Or do the voltage requirements not follow a linear scale with the dimming?

So I finally pulled the trigger and bought some stuff for my own DIY build. I bought two CXB3590s and one vero 29. A meanwell hlg120c1400a and a 4.85x22 heatsink from heatsinkusa that will have 2 92mm cpu fans on it. Going into an 18 x 24 fridge. Even after doing all the calculations, a few...

Has anyone gutted one of these and put COBs in? I have seen a video by growmau5 about a similar modification on a 400 watt Mars II and figure it must be possible for the 300, I just don't know what to do. Any LED gurus know what's up?

Does anyone have a suggestion for such a small light? I have a GalaxyHydro 300 in an 18 x 24 cabinet and despite all the hoopdilah about them being crap, I have been surprised by the good results it has put out. I'm not totally against DIY, but an off the shelf model for less than 300 would be...

It seems that all of my plants that are under led, in flower, are showing signs of magnesium deficiency. It is possible, although unlikely, that in ths batch of soil I forgot to put in any Epsom salt. This seems to be a consistent area of concern when using LEDs for me. Not really a big deal as...

Does anyone happen to have this model and if so, could I get a picture of it with no plants in it and with it turned off please? Thanks in advance!

So I just pulled the trigger on one of these quality pieces of imported technology. For 110 bucks, why not? Even if it does only give off roughly half the advertised power, I could buy 6 of them for the price of a Kind LED. Is it foolish to think that one of these will outperform CFL by itself?

Has anyone tried the LED conversion tubes? Maybe not the best for a full grow but for supplemental or sidelighting during flower, they can't hurt, right?http://ledt8bulb.com I'm wading into LED and can't swallow the 600 bucks for a quality light yet so maybe these are a cheaper alternative to...

A friend of mine asked me about a strain that won't make her eyes red when she smokes and I really didn't have an answer for her. Anyone know of such a strain that isn't too couchlocky? Is redeye even something that is strain dependent?

I have an opportunity for another stealth cabinet grow but the design parameters dictate that a drain free pot would be FAR superior to a pot with a drain. I have always grown with a few drain holes in my buckets but with organic soil do I really need them? I am using the square kitty litter...

I have a decent sized Canadian Maple tree in my back yard and some of the upper limbs are hollow. About 2 feet from the hollow knot holes I drove a few big nails through the side and into the hollow then dropped some wire mesh on top and loaded the holes with a couple gallons of a nitrogen hot...
