Transcript
- 0:00Hello there and welcome back to
- 0:01Hydroponics Daily, your go-to podcast for everything soilless cultivation.
- 0:06I'm your host Dr. Russell Sharp, the inventor of gold leaf as it's known in
- 0:11the US and liquid gold as it's called in the UK and that's a complete fertilizer.
- 0:17It's every nutrient in one bottle, pH perfect and it dechlorinates and so you
- 0:22don't need to have multiple bottles and you don't need to dose different products
- 0:27and that makes it really easy when you're dosing in line into a fertigation system.
- 0:32Now, as I said on previous episodes, if you have an A and a B fertilizer in
- 0:37your hydroponic system, you need pH control as well.
- 0:40So you'll need a computer to control the ratios that they go in.
- 0:44But at the basic level, the machinery you require to get the water in,
- 0:49we've talked about previously, that's a solenoid and a dripper and a spike and
- 0:54some sort of controller on that.
- 0:55To actually get the fertilizer into the liquid, then if it's a liquid fertilizer,
- 1:00you normally use something called a dosetron, and that's a water-powered chemical dosing pump.
- 1:08Now, there are lots of names for these, but normally a dosing pump is like the generic term.
- 1:14The main leading brand is a dosatron so everyone refers
- 1:17to it as a dosatron just like vacuum cleaners are often referred
- 1:19to as hoovers for that reason so this
- 1:23what this machine as long as there's water moving through the
- 1:26system it automatically injects a precise amount
- 1:29of the fertilizer maybe a disinfectant or
- 1:32a biostimulant or even a biopesticide pesticide into
- 1:36the flowing water without electricity so they're
- 1:39widely used in agriculture horticulture livestock for
- 1:42you know feeding micronutrients to animals water
- 1:46treatment and in sanitation so it mixes concentrated
- 1:50liquids into water and gold leaf or
- 1:53liquid gold is a concentrated liquid now it
- 1:56maintains a constant ratio of water to
- 1:59the liquid that it's mixing and make sure that it mixes it
- 2:02thoroughly at the same time so the machinery all does that all
- 2:05together and it gets the ratio
- 2:08by a setting on it now it have only one setting so it might only be a one percent
- 2:12dilution or many different dosatrons you can actually adjust it now for something
- 2:17like gold leaf in the us because it's such a concentrated product you really
- 2:22want like a 0.1 or a 0.5 percent.
- 2:26Ratio and a lot of dosing meters
- 2:29don't actually go down that low so really do check you've
- 2:32got the right one and the right dilution ratio
- 2:35to for the one you want like a one to a hundred
- 2:38would be crazy because that would be like a 10
- 2:41mils a one percent would be
- 2:4410 milliliters per liter and that'd be way too much because
- 2:47the product's so concentrated so it works on it works
- 2:50only from water pressure and flow water flows through the
- 2:53unit and when water enters the dosatron it drives
- 2:56a hydraulic motor inside the device then
- 2:59that motor powers a piston and the water flows
- 3:02mechanically moving the piston up and down and when
- 3:05you go to trade shows often the dosatron stand will
- 3:08have a one made out of transparent plastic so you
- 3:11can see it moving and mixing in real time and it draws a
- 3:14lot of people to the trade show stand because people like moving things
- 3:17and water and you know they get distracted by
- 3:20it that piston draws the chemical concentrates out
- 3:24of whatever it is your normally the bottle or the barrel
- 3:27that it's in and each piston stroke piston stroke
- 3:31pulls a precise amount of concentrate from a
- 3:34suction tube placed in the container and then that that on the downstroke that
- 3:39is injected into the water stream the concentration is direct injected directly
- 3:43into the water inside the dosetron and then proportionally mixed so that it's
- 3:48proportionally mixed to the water flow more water more product injected.
- 3:52Less water, less product injected.
- 3:54So the concentration is constant even if the flow or pressure changes, and that's crucial.
- 3:58So there's a motor, a piston, a chamber, an adjustment dial,
- 4:02and then suction tubes to get it in there.
- 4:05So the advantages are there's no electricity required, just the flow of water,
- 4:10which means it's great for off-grid situations.
- 4:13It's very accurate at dosing and can be used over a wide range of water pressures,
- 4:18simple mechanism, and it's reliable limitation requires a liquid concentrate
- 4:24can't be used for powders,
- 4:26And there is a pressure loss over the system. So if you're working with really
- 4:30low water pressures, it can reduce your water pressure.
- 4:32And it's not suitable for really viscous or abrasive chemicals.
- 4:36But even though gold leaf or liquid gold, as it's called in the UK,
- 4:40is a viscous product, it's not too viscous for a dosatron.
- 4:43So with a dosatron and water pressure, you can have a completely off-grid hydroponic
- 4:52system because you don't need a computer to control A and B.
- 4:55You don't need electricity for that.
- 4:57If you don't have water pressure because you're completely off-grid,
- 5:03then you could have a solar-powered pump that could pump the Dosatron and then
- 5:07take the fertilizer straight from.
- 5:10The gold leaf. The only thing you would need to do is to shake the bottle of
- 5:14gold leaf every few days to make sure that it's completely homogenous.
- 5:17But apart from that, it's completely self-sufficient. So you could even have
- 5:22a computer-controlled solenoid, battery-powered, that could set it to go on
- 5:26or off at certain times, so you wouldn't even have to be there.
- 5:30So the other option is a Venturi injector, which I'm not aware of, but I'll look into it,
- 5:35perhaps do another podcast about it if it's of interest
- 5:38so that's been hydroponic stated for today adding the
- 5:42dosatron the pump injector
- 5:45into what we talked about previously about solenoids and drippers so we've got
- 5:50the water with that then the dosatron the dosing pump just adds the fertilizer
- 5:54to the fertication system and you you look at a lot of hydroponic farms that
- 5:58do use a and b and ph up and ph down and might have a biostinulant.
- 6:02They might have seven dosatrons on the go at the same time, and there will be
- 6:07a computer to control them, and they might have to have sensors to feedback
- 6:11loop to control when those dosatrons are turned on and off in the valves and the solenoids.
- 6:16But that will be controlled by the solenoid running through each of those.
- 6:18It won't be controlled by the dosatron.
- 6:20They won't adjust the flow rate through the dosatron very rarely. You wouldn't do that.
- 6:26You would just control the solenoids going through.
- 6:29All right, that's been Hydroponics daily for today if you found this interesting then
- 6:32please leave a apple podcast review because that helps spread the
- 6:35word amongst the horticultural community about hydroponics and
- 6:38make sure you click follow so you don't miss an episode and check
- 6:41out utreema.co.uk where we have loads of interesting
- 6:44fertilizers biostimulants and organic biopesticides not just gold leaf and everything's
- 6:51unique and where you won't find any any of the technology anything close to
- 6:55their technology on any other nutritional type website okay thank you very much
- 7:01for listening until next time goodbye.
