Cheap coolbox from the charity shop upcycled into AA aero cloner. Nothing wrong with a bit of overkill ;)

You will also need to know what the 8% relates to, Si or SiO2. Nute companies have a habit of using oxide equivalents and sometimes, just to make it interesting, mixing elemental and oxide values on the same label ;)

Are you sure its algae? if the lines are black and the root chamber doesnt have light leaks, it shouldnt be able to get enough of a foothold to cause that kind of issue.

I would live with the algae until the end of the run as it sounds like your causing more grief to the plants than the algae ;)

Not sure what you mean, i use 26gal accumulators and charge them manually with a 160psi pump. I can add any amount from less than 100ml to 40L of nutes. I can predict how long the tank will run for, based on the tank pressure, cycle timing and system flowrate. If i need an extra hour or a full...

Running drain to waste and RO should solve the algae issue. I dont allow nutes to see the inside of my aero setups more than once. Prevention is better than cure.

Either your mist is too fine or there`s not enough of the larger droplets making it to where they need to be. If there is no middle ground between fuzzy umbrella roots and hydro roots that grow down, its a control issue. Figure what settings deliver which variety of roots and try a setting...

Standard stock solutions are typically 1:100 which is 100g of dry chem in 1L of distilled/ro water so for every 10ml you have 1g of dry chem. You can also make the stocks custom which will allow you to use equal amounts. You will have to do a test to see if the mag sulphate (epsom) reacts with...

Some brands of calcium nitrate include a small percentage of NH4 ;)

uptake of NH4 causes PH to drop, uptake of N03 causes PH to rise so it can be useful for ph control in recirculated systems. Typically, NH4 equates to less than 10% of the total N (90% nitrate) with dtw nutes but it can be a somewhat higher percentage for recirc and coco nutes. Urea is the one...

You are confusing weight with solubility ;)

Take a look at how this amazon chamber and lid interface is designed. 30 seconds in for the bottom and 1:35 for the lid.

From what i can see the hdx lids overlap the lip so the edge is outside the tote..not inside ;)

If you recess the lid so its inside and below the lip of the main tote it`ll never leak, unless you fill the tote up with water until it overflows ;)

Tugor sensors are too high tech for me. I never found chamber humidity useful for control.

The same as you do with other systems, let the plants tell you ;) You can also visually check the roots to see how moist they are. Using 2 seconds of mist would instantly quadruple the flow per misting and increase the mist density, which effectively reduces the space available for air. There...

Here`s a pretty uneventful but thankfully short vid to illustrate the concept of aeroponic mist environment. At the very start of the vid look for the visual reference points on the left, right and lower part of the screen to get an idea of the mist density present at the end of a 140 second...

Consider the thin layer of water on the roots idea being elevated to the next level, where the roots are surrounded by a relatively vonstant mist/fog which keeps them in the sweet spot. I guess the easiest way to visualise it is to imagine a theoretically perfect soil with zero machanical...

I didnt say too much oxygen was an issue, too much water/nutes "or" too little water/nutes/oxygen ;) Root suffocation due to restricted access to oxygen can occur equally well with liquid water or a high density mist such as ultrasonic fog. The key thing is whether you have the ability to...

If they get too much water or nutes or too little water, nutes or oxygen, they will grow slower or not at all ;) Different growing methods provide different levels of control and imho its better to have too much than not enough :)
