    Ventilation—Wye Duct & Sizes

    Do you think it would damage the fan by essentially throttling its intake? This is obviously unconventional bc I can't find much mention of it. And I know the filter would be less effective due to reduced carbon surface area. But it seems like with a tightly attached reducer, the 6" fan would...

    Ventilation—Wye Duct & Sizes

    Also I have an extra 4” filter laying around. Can I put a 4”- 6” expander on the —> side of the filter and attach it to a 6” fan? Can’t seem to find any answers to this on the Google

    Ventilation—Wye Duct & Sizes

    Excellent point about the back flow. I probably wouldn't have thought of that until it was happening and I realized why. I'll most likely just plan to run them both 24/7 in that case. Re: mold, I definitely don't want to trash my landlady's rental bc we're on friendly terms. I will try to do...

    Ventilation—Wye Duct & Sizes

    That bad huh? I’ve always had a low opinion as well. I picked it up bc I had one of the shitty plastic 4” exhaust fans for my 2x4, but in a matter of a few months I’ve expanded from a single 2x4 to a 4x4 and a 5x5 and didn’t have new fans in the budget till now. So I picked up the 6 inch booster...

    Ventilation—Wye Duct & Sizes

    Yea at least for now while tent 1 (5x5) is in home stretch of flower and tent 2 in late veg. Sometimes in early veg I’ll turn off exhaust for the 6 hours lights are off. I have an extra 4 inch fan and filter so planning to use that as my 24 hour flower tent fan in early flower and use the 6 inch...

    Ventilation—Wye Duct & Sizes

    Here's a vid I took of me climbing up into my attic which shows the vent fan I'm talking about. I could run the 8-inch duct line and clamp it right next to this exhaust fan which seems to run 24/7

    Ventilation—Wye Duct & Sizes

    Good call, except I live in Phoenix, AZ, one of the hottest, driest cities in the world. There's also an existing exhaust fan in the attic that exhausts the hot air out 24/7 already. If I run the duct right up to that roof vent fan, do you think I'd be ok? It's already back to being 77 or 80...

    Ventilation—Wye Duct & Sizes

    Sup Rollies, I have a 4x4 veg tent and a 5x5 flower tent nearby each other in the same small office and it's getting HOT in there. I live in one of the hottest places in the world and our 3-week long winter is officially over, so I can't vent into the room anymore. I just bought a 6-inch...

    AZ Winter Greenhouse Grow

    FWIW I just compared the changes in day length of my current locationwith those of the area I’ve grown (and lived) previously, in far northern New England. Phoenix, AZ Day Lengths Jan 15: 10h 10m. Mar 15: 11h 57m. Diff: 1h 47m Burlington, VT Day Lengths: Jan 15: 9h 10m. Mar 15: 11h 53m...

    AZ Winter Greenhouse Grow

    Yea the auto light dep greenhouse has been my dream setup for a while now. Definitely not going for anything that serious at this point in my life. Strictly a hobbyist for now. The conversation I’m referencing definitely wasn’t about light dep though; or else they wouldn’t have been discussing...

    AZ Winter Greenhouse Grow

    Interesting, I definitely wondered about that, but I figured I'd be safe before the equinox. I could run a small light in January and February to keep it at an even 12 throughout the winter I guess. Definitely not pulling tarps all Feb and March tho Would be curious to hear any other input on...

    AZ Winter Greenhouse Grow

    Hey Friends! Anybody else here in the PHX AZ area, or in a similarly hot desert climate? Now that Arizona has legalized home grows, I’m considering putting a 6x8 Harbor Freight greenhouse in my sunny, walled-in backyard and putting a few plants in there for a winter grow. I would start them...

    Arizona Outdoor Grow ?

    Damn that's crazy I was about to post almost the same question, with the exact same background! I moved to Phoenix from northern Vermont earlier this year. Considering a small greenhouse grow in my walled-in backyard, now that home grow is legal here. I was going to start six plants under an LED...

    Maximizing Vermont’s 6 count plant limit

    Here’s a summary of current civil forfeiture laws in VT. http://ij.org/pfp-state-pages/pfp-vermont/ They were amended to allow 45% of assets or proceeds to go to law enforcement in 2015, before the current Scott administration, and prior to any of the recent legislative efforts that culminated...

    Maximizing Vermont’s 6 count plant limit

    That is... curious. I will have to look further into the civil asset forfeiture change. The one ounce limit is for carrying on your person or in a vehicle. You can have any amount of homegrown within your dwelling as long as it is stored securely and away from public eye.

    Maximizing Vermont’s 6 count plant limit

    Reading over my own plan, only changes I would make are: take clones earlier to allow two weeks for rooting and four weeks for veg before potting up to 25 gallons... much more realistic. And, I happen to be aware of a certain jack herer fast pheno that produces amazing, glistening sticky...

    Maximizing Vermont’s 6 count plant limit

    Howdy neighbor! Been pondering this exact same question. I can post the whole 3-tent SCROG cycle schedule i came up with after work if you’d like. It’s definitely right on the edge of legality, but I’m comfortable it would be worth the additional yield. It assumes the first four weeks of 12/12...

    Greenhouse Plastic Sheeting to seal lower half of room?

    ’Sup RIU! I’m delving into the world of CO2 supplementation and sealed rooms for the first time. The perennial conundrum is: how to keep room cool efficiently/cheaply while conserving as much precious gas as possible. Right now my set up involves a portable a/c vented to an external air cooled...

    When to boost lumens during flowering?

    Ya, I do tend to over-complicate things. I was also thinking that the best strategy might be to crank them to 750w each on cooler nights (I run lights at night) and dial them back down to 500w during warm spells. It would be interesting to hear if any research has been done into when flowering...

    When to boost lumens during flowering?

    Howdy RIU! As we head into the warmer months, I’m planning on scaling down my basement grow somewhat. I currently have two flower tents with a total of 3000 watts of HID and 950 watts LED (330w COB in one; 620w HLG Quantum in the other), plus an all-COB veg tent. Starting after chop next week...
