Does the light have to be at full wattage all the time? Suppose I am in veg. Can I run the light at full wattage for 10-12 hours and dim it down to 50,30,10% for another 2-6 hours to prevent flowering? If so, how do I decide how much to dim it by? Thank you

So, I was thinking about upgrading to HLG 650R board light some day: https://horticulturelightinggroup.com/products/hlg-650r Because it's so powerful, the manufacturer recommends not hanging it any closer that 30 inches from the canopy. Add the thickness of the board and a couple inches of...

Hi, Can you guys recommend a fan+ filter that would be able to eliminate odor completely from a 4x4 tent? Also, quietness is a must. Is there a capable, truly silent fan out there that won't break the bank? Did anybody ever try using a dual filter set-up? Like 2 filters on 2 ends of one...

Who are you replying to?

If nothing else, there research that shows increased germination rates. H2O2 supplies extra oxygen across the membrane.

Thanks for sharing. Ed Rosenthal recommends using 1 part drug store peroxide (3% strength) to 5 parts of water in his book. Last time I tried to grow, my seedlings sprouted, but died from damping off a ~week later later, even though I didn't overwater. I read that they can come from breeders...

It's not just weed. It's a precious being that I want to thrive and become a tasty, sticky, colourful cutie-patootie. c:

Does anybody here germinate in a glass of water and H2O2 to kill pathogens and aerate the seed? What proportions of peroxide to water do you mix?

What's their "true" equivalent wattage? Like, if a blurple draws 200 wt from the wall, what's its true HID equivalent?

Appreciate the insight! How many would you grow in a 4x4 tent? How was the yield/effect? How long did you veg, flower? Did you top? If yes, when? When did you ScroG? Would 2 blurples with 240 watt from the wall each (allegedly 600 Wt HID equivalent per each blurple) be enough for a good veg of...

Thank you, that's an interesting idea, but I just checked Home Depot's website, and plywood is ridiculously expensive (2x4 easily ~30 bucks; 4 sides - ~$120 + 2''x2'' + top and bottom. Building a box would cost more than buying a second tent. Maybe I'll seal the closet with plastic bags and...

I have seeds. Supposed to be pure Blissful Wizard. I also have Grand Daddy Purple and a cross of San Fernando Valley x Sensi Star. I want to grow all 3, but I really prefer sativa effect, so I want to have more of Blissful. I was thinking about doing it in a 4x4 tent with 2 LED Blurples (240...

Why 78?? Everywhere I read, it said 80-82 was the borderline for flower, never to go above that. Everywhere I looked, they recommended 68-75, 80 being borderline. So, why would I want to go 78 F--so close to the borderline? (Sorry for the large green font--just trying to make it easier for you...

Why? :)

So, I got a hold of this strain. It's famous for winning 1st place in the 2015 SoCal Cannabis Cup as a non-solvent hash. It' a cross of GSC (which I love) and Captain Cookies. I never tried Blissful Wizard, but I love GSC, and folks say BW provides the kind of energetic, warm, focused kind of...

^^ Does my train of thought make sense, or is it flawed somewhere? Constructive critique is welcome.

I am planning to start the grow soon and finish around January. I am in a cold state, so getting rid of heat shouldn't be a problem (as in cracking the window open). Humidity in January fluctuates between 79 (morning) and 57 (afternoon), so I'll just keep using a dehumidifier. My goal humidity...

So, I am planning to grow several different strains in the same tent. It's gonna be my first time. Different strains will probably have different flowering time. I need my room (let alone my apartment) to have no odor whatsoever. I have a budget for only 1 tent, so when some plants will...

600 watt CMH + 2 LEDs: 240 Watt from the wall each, claims to be 600 Watt HID substitute each. So, 600+240+240 = 1080 from the wall (1800 Watt total HID equivalent if the 600 watt LED claim is true) for a 4x4 tent: It won't be an overkill, waste of electricity, and a risk of light stress?

Thank you for the responses. I appreciate it, guys! My friend has a VIVOSUN Ceramic Metal Halide. I don't remember if it's 300 or 600W (his gf used to grow veggies). He offered me to borrow it. Would supplementing these 2 hydrocrunch led's with a 300W or 600W CMH do the job? Should I use all...
