2016年12月12日 · re: PPM & Nutes? If your base ppm is 600. You'll only want to add enough nutes to raise about 200. So total ppm would be 800. Start low and slow. Mine are bout two weeks old and ppm is 400 at most and THIER doing good so far. My base ppm is 250 So my meter reads 650. Going to raise soon. Hope this helps.

2015年2月16日 · Hey guys been doing a lot of research around PH levels and PPM and what is optimal for cannabis plants in DWC particularly the strain OG Kush, there are loads of different ranges out there that work for a lot of people but if someone could help me here and give me guidelines from (seed/clone - harvest), i would be so thankful and all feedback ...

2015年1月5日 · (700ppm) .. in the past I never added CO2 in veg and my ppm in flower was 1400-1500. Also... I flower with temps higher than 72deg air temp... As stated in the 2nd graph and from my experience... the higher the temp.. the more benefit from high CO2. Everything I have read says running flower at 88deg and high CO2 will outperform 72deg and 700ppm.

2022年6月19日 · From the graph above the EC meter and thermometer match at 8°C and are within 1°C of each other on incline. This meter's temp reading is more accurate below room temp than it is above - from my experiments. The eBay advertisement claimed, 'Ultrahigh Accuracy'.

2010年3月11日 · EC stands for Electrical Conductivity and is a measure of the strength of the nutrient solution. The higher the conductivity, the more dissolved solids there are in the solution. EC is just one format of measuring the nutrients. It can also be measured in PPM (Parts Per Million), and TDS (Total Dissolved Solids).

2019年2月12日 · the reason I don't believe any of this is bullcrap is that I cross-referenced it with some other papers and the information is very very close to other sources (these guys just have easy to read graphs instead of walls of text) .. also they didn't try and recommend their lights vs others ... this is just raw data and can be achieved with any LED/HPS/MH ect. light on the market if you know what ...

2020年1月28日 · I live in a part of Canada that is right at the top of the graph of cities with the hardest water. Because it is nearly entirely sourced through bedrock. Tap water stats for Waterloo, ON: pH of 8.3. TDS/PPM of ~350 (only in my neighbourhood, some areas are 700+!) . Heavily chloraminated So right off the bat -- our water from the tap is nutty.

2016年10月25日 · For the purposes of these latest tests I made a ph balanced medium strength (500 ppm) solution of my regular grow feed nutrient. Ph of the nute mix was at 5.6 before adding the calmag stuff.

2021年3月16日 · For example when you apply an iron foliar fertilization regime you generally use a concentration of 500-1200 ppm of Fe while in root applications you only very rarely go beyond 4-5 (most commonly 1-3 ppm). Usually concentrations in foliar fertilizers will be much higher and if the fertilizer is correctly designed this will give much better results.

2010年7月12日 · PH and PPM: What is PH? PH stands for "Potential of Hydrogen". And PPM stands for "Parts Per Million". PH is one of the most common analyses in soil and water testing. An indication of the sample's acidity, pH is actually a measurement of the activity of hydrogen ions in the sample. PH measurements run on a scale from 0-14, with 7.0 considered ...
