    Aeroponics accumulator tank charge

    High pressure aero requires a water pressure of no more than 100psi, air atomising nozzles no more than 40psi air pressure.

    Sulphur Amendment in Hydro

    If you arent using RO water you will likely have enough sulphate in your base water. If you use tap water, the water company will usually provide a quality report which listts the elemental content. Excessive mag can cause issues with potassium especially in a recirculating res.

    Aeroponics accumulator tank charge

    The type of aero you are thinking of uses siphon fed air atomising nozzles. An air compressor tank, technically a receiver, contains only compressed air. An accumulator contains compressed air and water which are separated by a bladder or diaphragm. Water is not compressible, when you pump water...

    Aeroponics: problem with clones

    If you have a piece of coco mat under the puck you can just drop the seed down the hole.

    is organic aeroponics possible

    I wouldnt recommend the standard Amazon. The root chamber is small (50L tops) but it takes up a fair bit of vertical space with the res being underneath.

    My guess is they used ammonium sulphate to increase S, the NH4 was more a consequence of the choice of chemical than an elemental target.

    I wouldnt recommend using the 5-12-26 as a sub for the 7-15-30. The 7-15-30 uses ammonium sulphate to provide a big chunk of the N and the sulphur boost.. You could amend the 5-12-26 with additional ammonium sulphate but it will be 30% light on P and K compared to the 7-15-30. The main problem...

    lol, converting gals and litre is confusing, its easy to trip up. I`ve editted the post above to reflect the dose should be ml per Litre not per gallon. If you want ml per gal simply multiply by 3.785. The calculations were just for the jacks and calcinit, no additional epsom. To make up...

    Easy enough to figure out. 2lbs is 907.185g, when dissolved in RO and topped up so it s exactly a gallon (3.785L) you will have 239.6g of jacks in each litre of stock (907.185g/3.785L) The stock is 1: 239.6 Divide the 239.6g by 1000 and that tells you 1ml of the stock will contain 0.2396g of...

    Jacks has a lot of Mg without the epsom but you can combine it in a 1:100 jacks stock. At 1lb/gal its is close to 1:120 but epsom is very soluble at 1130g/L @ 20c

    You should be ok with a 1: 200 jacks stock as long as its not kept below 20C/68F. The calcinit solubility is no problem, 1200g per litre @ 20C.

    Stock solutions should be made very accurately to ensure repeatable results. Weigh 1000g of RO, pour it into a clear container and mark the level. Tip it out, add 100g of jacks to the container and add RO up to your 1L mark. Wait for the chems to dissolve completely and then top back up to your...

    Hydrobuddy calculation inconsistencies

    The manufacturers will have access to labs to test their product so what they state on the bag should be correct, subject to tolerances. If you buy the chems from ebay and they come in plain ziplock bags, all bets are off :) An EC or TDS meter cant measure elemental ppm so you have to trust...

    Hydrobuddy calculation inconsistencies

    I use stock solutions to make up nutes but i use weights to calculate the elemental ppm of the formulation. For example, my calcium nitrate stock consists of 500g of chem, dissolved in 4L of RO and then topped up to exactly 5L. I know 10ml of the stock contains the equivalent of 1g of calcium...
