    Hey bro! Happy late holidays. I'm doin great, that last crop pulled down just over 10 lbs. So ended at about .8 GPW from the Gavitas with NO CO2 injection. I'll get pics up soon, sorry for delay.

    polyarcturus *5star* general thread

    Sodium isn't salt... Your links simply say that drainage is used to reduce salts... Gypsum increases drainage.. Your link speaks of saline soils (soils high in salt). If your soil is high in sodium it is known as "sodic." Soils that are high in sodium have a different electrical charge to...

    Gypsum? Calcium sulfate... How does that neutralize salts? It provides calcium and drainage..

    Sorry for huge delay. I think cal/mag is necessary here and there for RO. I don't DI. I do use cal/mag but not every feeding. When first feeding in coco, I use 2 mL / liter, or roughly 7 mL / gallon of A and B.

    Just love the Gavitas... There's no way you can veg with them though.. Even set down to 600 watts they stress the plants in Veg. Once I flipped em into flowering they perked right up. On the money, thanks a lot bro.

    Wow, that's the lock of the century. If you can get a 1000 Pro DE for $440 I'd say jump on it... Mine were 580 after my discount, and I am definitely at the highest tier of price drops I can get. You will definitely need AC, however, unless you upgrade and get the ducting they sell for them...

    Your local store must have the 600 watts for them to be $440, those are $400 at my local store. And the 1000's were $600 a piece, not including discount. They produce as much heat as any 1000 watt. Average of 3.4 BTU's of heat per watt, so 3400 BTU's per 1000 watt. We have a 36,000 BTU AC...

    You asked for it. I tore down the grow I had going at home, it was in a spare office I have and I had the funds to lease a small warehouse space. Did a pretty serious build out in it. 6,000 watt flower, all Gavitas.... Here it is almost finished. Decontamination room: Where we change out...

    Sorry for delay in response. Last grow of full room of WiFi yielded .8 grams per watt, about 3.2 lbs from (3) 600 watt lights

    Got some veggies runnin at home. Every time I've turned on the Gavita they just kinda droop and stress out. Gotta wait til flowering, it appears. They just don't need that much light in veg apparently. No pics as of late.. but i'll see what I can do ;) Ya that place is pretty big, but...

    A little morning foliar that hadn't dried before the lights turned on. They get it once a week for preventative measures. Azamax and GoGnats root drench once a month as well.

    Very nice snag on that WiFi man. I let mine run about 63 days, after the 9th week I see a nice blend of trichome coverage. They really just beast once you start kicking up the PK in the middle of flower. Just don't put it on too soon. wait until week 3 to give it to em. CANNA dropped a new...

    I've a good buddy who had the same dilemma. He went with the 600's but worked his way to the 1000's and is much happier. Gavita does make 600 watt bulbs in this same style. They also have other styles of hoods which resemble the more classic look, the triple star is a sick reflector that can...

    Things are coming along. I'd say the MambaXDUD, as well as White Fire are about 10 days out. We'll see what the next fertilizing does. It may be the last and the onset of flush for the early girls of the first group.. Lemon Larry looks like they can bulk a little more.

    No stress. I didn't think you were trolling. Just a difference of opinions. I don't mean to come across as adversarial. The problem I see with having to lower the hood with your cooling is the reduction of light spread. Say you want to overlap your lights and really pound the lumens on...

    Haha, i totally hear you. "Too much heat problems? Get a bigger AC!"

    I do remember that video. Gavita has been testing in the industry for a very long time. I would enjoy seeing your video where air cooled hood out performed the non air cooled hood. Everything he says in the video makes sense. Also 5-8% of light loss through glass is a very agreed upon number...
