Hey GWE community! Just went out to find my plants basically on the verge of death after an intense spraying of Neem oil due to spider mites. This is what I get for putting in 150 days of work and tons of money in materials and nutrients?! Fuck that bullshit! You all can have it! I'll stick to...

Howdy GWE community. I currently have a 600W MH/HPS set up that I used to use in a custom-built grow cabinet. However, I recently built a larger grow room in my garage and I want to upgrade to this 1000W system to get better light coverage. So my question is would it harm the plant in any way to...

A recent study by the University of Colorado at Boulder suggests everything we know about the strength of marijuana is wrong! THC levels don't translate to a better high. I personally agree with this study as I don't see any difference when I consume very high THC percentage bud versus very low...

Hey GWE community! I have a 10 gallon DWC system and I was looking for input on doing my nutrient change. ​​​​​ Which is a better way to change out your nutrients... Pre-mix in two 5-gallon jugs then pour into the reservoir OR fill the reservoir with plain water and add nutrients...

So, long story short, I'm a southern boy who grew up in heat and humidity and never knew what "dry" meant until I moved to western Colorado. That being said, growing cannabis can be a struggle with such dry air. Sure, I don't have to worry too much about bud rot but I do have to worry about slow...

Hey GWE community! I am getting a head start on my winter grow by researching heating sources for my garage and wanted to see what you all thought about using a portable propane heater to warm my grow room. Since my room is highly vented (390cfm in a space that's 234 cu. ft.) CO toxicity...

Researchers from New Zealand found that cannabis causes bronchitis, and in heavy users, it can lead to irreversible lung damage According to a new study out of New Zealand, heavy cannabis smokers could experience a destructive lung disease called “bong lung.” The study, which reviewed...

Greetings GWE community! Today I learned a very important lesson on how to use my ActiveAqua water chiller and I wanted to share it with the community in case anyone else gets one. First, choose the right size chiller for your setup. For 10-50 gallon applications you can use the 1/10 HP model...

Hey GWE community. I was just curious as to what people thought about nutrients and expiration dates. Have you noticed that nutrients "go bad" after a certain amount of time or can they last with proper storage? I'm asking because my first grow as about 2 years ago and I had some left over...

After hearing that Jeff Bezos, America's first 5' 7" tall penis, is about to become a trillionaire, I'm terribly sorry I ever gave him business. I know I won't be doing it in the future! So all those things I linked on my first grow and the few on my second, BUY THEM SOMEWHERE ELSE! NO ONE...

So my surge strip just went off again and when I turned it back on the light wouldn't come on. It quickly tries then goes right back off. Isn't that a bad ballast or do I have a bad bulb?

Hey GWE community! I recently bought an ActiveAqua 1/10HP water chiller and installed it but I have one question...when doing nutrient changes, how do you flush out the stuff in the actual chiller? Basically it's driven by my pump and once the pump is off, the water stops moving. Well, there is...

Hello GWE community! I have been gone a couple of years but I'm back and I'm about to start my second indoor grow. Last time I built a custom grow cabinet and managed to get a little over 10 ounces off of two plants using a 600W light. This time, I've built a custom grow room. Here is what I'm...

I hope everyone out there reading this has a safe and happy holiday! Be sure to get your fill of your favorite foods and enjoy yourselves! PS...I didn't make this but it was really cool so...

Greetings all. I am making a drying cabinet out of an old wooden cabinet I picked up for next to nothing on craigslist. It's a split door cabinet that is 4x2x6 and the drying area is 2x2x6 (24cu.ft.) I plan on installing a 4 inch duct starter on top, hooking up a run of 4 inch ducting to that...

Probably a very stupid question but at this point I really don't have anything to lose by asking it! Can I smoke my crop if there are spider mites all over it?! I just discovered the infestation about 2 weeks before harvest and I am probably going to lose my mind if I just wasted 4 months of...

Greetings GWE community! I am getting close to harvest and wanted to know about using products such as Flora Kleen from General Hydroponics. The feed schedule calls for it to be used a week after the last nutrient feeding. However, I was wondering if it would be better to use it right before...

COOL! The forums are back up! Lots to catch up on! Thanks GWE webmasters for getting it back up!

I really want to buy a BlueLab Guardian monitor for my next reservoir but I have read a number of reviews that say the pH probes don't last very long and wanted to see if any of you have used them or are using them or know people who use them before I fork out that much money. My biggest...
