http://www.jacksprofessional.com/ 5-12-26 Hydroponic THE fertilizer to use for hydroponic plant production. It is easily modified to fit specific crop needs and individual water qualities. Supplies magnesium and sulfur with 100% nitrate nitrogen. Comes in 25 pound bags and is less than...

Sorry for your loss but it's due to your hand. New guys tend to "play" with it too much. The carboload is organic and you could have just added cane sugar and got the same death. Organic compounds are not acceptable in DWC systems. Pull yourself up by your boot straps and start over...

Free shipping too! And what if your local grow shop is 40 miles one way? At $3/gal of fuel that's like $15 round trip in my truck.

I have found that adding 1 tsp per gal. of solution per day of common 3% drug store h2o2 is cheap insurance along with keeping res temps under 65f. "The key to big productive plants is a big healthy root system and Hydrogen Peroxide is a great way to keep your roots healthy. It is a must to...

Too complex and the misters will clog. Just make a manifold using a few feet of 1/2 pvc one tee and two end caps and have the water stream out against the tote.

Distilled water=diet coke=starved plants.

Repot what you have into soil and start over with rockwool/rooters in netpots.

You need a ppm meter. Take that water pump and make a manifold out of 1/2 pvc that squirts 4 streams of water against the tote. You can buy a cheap 15 min on/off cycle timer as a controller. I use a 18 gal tote with just three gallons of solution with a water pump setup using only 1 tsp of...

The smart way to to it w/o the masters degree would be it use a simple gravity feed IV drip with a manual control valve. If you keep proper records you will know how much solution will be needed in a 24 hour period. Take the amount of ph down needed mix in a solution of 128 oz of h2o with...

There is noticable daily growth. I have 12/12 clones from start to finsh taken from mom at day 14 of flowering so it's like bonsai. Not normal growth to big with...

I am at 53 amb temp with 60 res temp and my daytime temp is 74 inside the old tron with 300 watts of flouros. Using somewhat of a CFL Lucas formula slow and steady wins the race. I have a 100 gph water pump ghetto aero setup running one hour off and one hour one (going to 15min on/15 min...

I am doing this with an 18 gal roughneck with six sites using 4 gal of solution. I canned the misters becuse they wlll clog and use four piss size streams from a diy manifold with a 160gph pump running one hour on then one hour off. Your best bet would be to work on root density vs. length.

Again what is ph down made from? http://en.wikipedia.org/wiki/Ammonium_sulfate 21-0-0 http://en.wikipedia.org/wiki/Urea_phosphate 17-44-0

Let me explain the science of the ph battle and how you can live within the limitations of high ph tap or well water. When you have 7.0 ph water and you use GH ph down you are adding ammonium sulfate, citric acid, urea phosphate. Now two of those above chemicals are pretty much pure nitrogen...

If the outlet of the pump does not break water there will not be any sound. I don't see any problem with res temps as low as 50f as long as the nutes can be held in solution and the daytime temp under lights does not get above 65f. Depending on the space that could (cold) be ambient temps of...

The best heater may not be a heater at all but a sub pump. Petco has two sizes for sale (I would get the bigger one for its just a few more $$) they call it a power head for an aquarium filter. PETCO Power Head Our PETCO fully submersible power head with its unique design creates...

I have found that by adding a 160 gph or so water pump with a self made PVC manifold makes for more root growth, keeps the roots cleaner, and more nute uptake. Forget about the nozzles they just clog. Just drill into the PVC with a bit big enough to make a piss size stream that will not clog...

It would be easy to dump the waste water under the shed but you still need to clean out the bucket. An extra bucket is all you need to give the honeys an air bath in the process. I find that the 12 quart sterilite totes with the white lids and clear bottoms for $3 to be better than a bucket...

If you don't have much money cheap fixtures for 26watt cfls can be made with extension cords, medium base Y's in triple configuration, eight inch stove pipe, double lamp sockets and a bunch of other junk you might just have laying around the house. A hanging 4 light three "Y" 26watt CFL...

My phototron dwc/low pressure aero hybrid A few months ago I pulled my old 36” tall three-flouro 120-watt model out of mothballs. After many tweaks my science fair project is ready. My growing vessel is a three-gallon stainless steel stockpot with six 2” perimeter sites with two...
