    RDWC Gurus, need advice on return line flow rate.

    I ran a three Waterfam rdwc grow and used a 5 gal bucket for a reservoir... I set the WFs on cinder blocks so i could fill the reservoir almost to the top and still have the water level the same as the grow buckets... Didn't check the date of the last post.... Do you have a thread of the system...

    ***DAT's Art Cave***

    I know this is way off topic, hope you don't mind.. Ran across you on another site asking about the 315 watt lec mh a while back... went and bought a couple to see if they are as great as they claim to be,, seems that they are... 26 oz These two are in waterfarms...

    Max yield from a 600w hps

    For most growers, 2lbs with a 600hps would be possible only in their dreams.... For the rest of the growers, next to impossible... You could veg in scrog screen for three months, then flower.... I still doubt you could get that large of a yield.. We're talking about prime buds... The solution...

    Used Lucas formula until i switched to FNB http://gh.growgh.com/docs/LABELS/floranova_bloom.pdf.. It has everything the LF has and more.... The label says it all... buy a qt. and give it a try...

    The lights were hung at about 24", first started at 30" then lowered.. That's gives me a good 32"x 32" , 45 watts sq. ft.coverage, though as you can see they really do try to lay down and spread the last couple weeks..... The screen they're in is 84"x 24",with a small plant under an advanced...

    1 plant dwc scrog

    just plane water and cut the hours to 11/13.... on my last grow my 2 WFs seem to leach leftover nutes from the hydroton that had somehow been deposited through out the grow..... I took a week of feeding plane water to get the ppm to drop to 200..... I always make sure the drip ring is in the...

    Scrog Advice!?!?

    Here's a link that'll show how a scrog should be done.... It's not just about growing a plant through a screen... it's about keeping a plant below the screen until you tell it to start it's flowering stretch by switching to 12/12...

    1 plant dwc scrog

    The WF bucket handles were not rigid enough so i cut an 1/8" thick piece of abs to fit between the clamps and the bucket handle... It doesn't take a lot of force to clamp the 1/2" pvc tee tight enough to support the frame......

    1 plant dwc scrog

    Did this mod so i could move the Waterfarm and scrog screen.... I've since made one more mod to beef up the handles for clamping the 1/2" pvc tee to the wf....... none of the 1/2" pvc is glued together for the 24"x 30 screen... I'm a certified, card carrying, Waterfarm Pimp...

    The 315 lec has a small footprint, so i use one lite, one plant.... The Blackberry yield was 11 oz + about 2 oz of light airy buds..... The BM came in at 14 oz, plus the airy stuff.... The 315w lec, as good as it is as an all round light, doesn't mean you can't do as well with a 430 watt hps...

    Wanting to set up a DWC

    First you need a 4 legged tomato cage... Cut the top ring off... Then you bend the wires that are sticking up, at a 90* angle... It's important to bend the wires a 1/2 inch above the ring... if you try to bend the wire where it's welded to the ring, it'll break every time... ask me how i know...

    Quality air pump?

    I went from 1000 watts hps to 600w hps, sold those, bought 2, 315s, 110 volt... just finished my first grow with the 315s.. Here's two waterfarms a couple days before harvest, first first is Nirvana Blackberry, second is Blue Mystic..... Good example how different strains stretch in flower...

    Quality air pump?

    Have used the GH pump for the last 5-6 years... Bought a rebuild kit at the same time and it's still on a shelf.... I've used it with 4 waterfarms at a time, they claim it will do eight... You realize of course that the hole for the water spout in the igloo water cooler will take a 1/2 inch...

    The Official Dwc Cooler Club - Any Kind of Cooler Res

    About time to kick the can down the road a little further... Did this last summer.. Two 5 gal. igloos, one to grow in, one as reservoir....

    Minus 40*f, i can't imagine it being that cold... We're having a bit of a warm up here... mid 70s*f this entire week... Being about 50 miles east of Death Valley.. we run about 15*f cooler than DV in the summer... Did have a few cold nights in low 20s*f, for a couple weeks... I guess that's...

    Starting seed in hydroton w/o rockwool?

    Change the way you plumb your 8 waterfarms and each waterfarm pumping column will pull it's own water from the reservoir... Every WF will take water from a feed line connected to the reservoir, then gravity returns it via a return line to the reservoir..... If you have eight WFs pumping, each...
