    Fairlight C99 and Nirvana Northern Lights 400w Deep Water Cooler (DWC)

    Just harvested NL, probably got 2.5-3 dry. I burnt them around week 4 as well. Def. slowed them down. Pulled at the same time as Bubblicious. Bubble tastes and smells much better, but the NL will make you lose a couple of hours in the day in the blink of an eye. There's that couchlock for...

    What size dehumidifier in 4x4 tent?

    Get the 45 for sure. I have the 70 pint/day model for a 5x7x7 room. It doesn't run that often, but they sure put out a lot of warm air. You might be getting that tent too warm if you have one running for long periods of time. As far as electricity goes, like the person said above, during...

    5 Gallon DWC going into flower - Nute Question

    Those sound like pretty high PPM's. I try not to go over 900-1000. I find that PH really starts to fluctuate at that level, and don't really see any added growth. My 2cents

    Convince me I need to drain and replinish every week.

    I try for every week, but I like to have some schedule. My recommendation to you is to use Cal/Mag, you're using R/O water, you will show signs of deficiency in another week or two, those little necrotic spots on the leaves. Don't think it's another def. and nute the hell out of them, that...

    DWC feeding schedule question.

    I've found with DWC, keep the PPMs on the low side, don't need to go over 900 PPM, even at the peak in flowering. You'll avoid a lot of issues if you keep the feeding light. It's very easy to over do it. If your using R/O water, get yourself some cal/mag. I have a friend :) that uses...

    Carbon Filter questions

    I got a 6" inline, 405CFM, Hydrofarm, cooling 2 600 watt hoods. Keeps temps in check, but my intake air is only 58 F. I do have 3 90 degree elbows in the line, which I don't recommend doing, you lose serious airflow everytime you have a bend. Something I need to change out after this harvest...

    What type of odor control..?

    If your concerned about odor control, don't skimp. Get at least a 4" centrifugal fan and carbon scrubber to match. Expensive, yes, but so aren't lawyers. No matter how many plants you have, come mid flowering, they will stink up your house without proper scrubbing. Unless of course, your a...

    My Grow Setup, Let Me Know What you think ;)

    As far as the CO2 goes, if your room is completely sealed, no leaks, hanging out in your room will raise the levels up significantly. I have a 6x7x7 tall room, fuzzy logic controller from CAP, and after 10 mins of being in there with the door closed, my levels are up to 2500 PPM, which is a lot...

    Has anyone tried these hydro pots?

    I have one of these pots, it came with my bloombox. It said to use Coca, or however you spell it. It is pretty simple to use, but it is a little small for a full flowering plant. Maybe 1.5 gallons. Works great for a mother plant though.

    White Russian Yield Help

    Is this your first time growing with this box? I've had one for a year now. Don't use rockwool, it stays way too wet in there. You'll have lockout all the time from overwatering. Switch to either rocks or hydroton. Second, your going to have to top these plants 2-3 weeks into flowering. It...

    My hydro setup + ?'s

    Rockwool sucks in DWC. It stays too wet, especially if you submerge it in water. It's like a sponge. Use hydroton, or just some rocks. In my experience, I ended up getting nute lockout because it was always wet. Severe PK deficiency later in flowering.

    Grow Room Planning Stages!Opinions!

    You should pull air through the scrubber, through the hood, then vent outside the room. If your getting temps that high 1.5' under the light, an oscillating fan is only going to work for a little bit. Eventually, the whole room is going to be that temp, especially at the end of a 12 hour light...

    HELP x2! Beginning of 4th Wk of Flowering, Plants Got Ugly Fast PICS!

    H202 is key in hydro. Can't use it with Beneficial or anything organic though, must use with chemical nutes or the peroxide will kill the bacteria making that much more of a mess in your res.

    +REP need help quick hydrogen Peroxide

    Everyone has their opinion, and every set-up is different. I posted in your grow journal, but in case you didn't see it. I get 3% in a 1 Liter bottle from Target for 99 cents. I have a bloombox, total of 9 gallons between veg and flower, bottle lasts almost two weeks. I add 10 ml/ gallon...

    Big Buddah Blue Chesse First Hydro Grow in Mothership

    I started using 3% in my Bloombox, never had better results, roots are white as can be. I use 10 ml per gallon when mixing up a fresh batch, as well as in any water I use to top off. It seems to be working just fine, I haven't pushed the boundaries with it, but I can tell you that you can back...

    trueloveforever164 5th Grow – Bloom Box Sensi Seeds Big Bud Feminized

    Did you do the T-5 upgrade? I did on mine, it definitely helps the lower buds, but makes all the bottom leaves curl down towards the light, almost makes the plant look overwatered. Your plants look good though. How did those G-13's come out?

    CLOSET GROW - Problem - Fan leaves falling off, others look to be drying up WHY?

    That's a whole lot of P in the nute formula. Toss that stuff and go for something with a better ratio. Sounds like your plants need some Nitrogen. Despite all the hype, you should really be feeding them N all the way through. Plant can't make buds if it doesn't have any leaves to work with...

    I need Advice!! Plant became nuted burned, flushed twice, and is still burning!(PICS)

    Could be a N deficiency though, creeping right up the plant. Your in week 3, that thing wants to grow, it should be eating quite a bit, unless your using low light, in which case, most likely burnt.
