thanks for the feedback jelly! Yes, the main front page site is pretty slow, since it has videos and a lot of media. The actual shop page should be pretty quick, since it skips all that media and just gets to some core files
So, for the main page, we have some different options but I am not sure the best way to go about it now. We would like to keep all the information there (since there is quite a bit of details and info about various ingredients), but reducing the media/pictures/video would make it load faster but possibly make it less interesting. So, definitely something we are looking at!
For the PPM feeding, it varies a lot between different PPM meter brand and types, so it can be confusing or actually give wrong information to some growers if they are using it alone. EC would be more of a universal measurement, which we would like to add soon.
If you want to measure PPM, you can just measure your first reservoir with grams based on the feeding chart. After you measure grams, you can let it settle in, and measure the PPM with your meter. Then, in the future you can skip the measuring part and only measure with your meter, and it should give near identical results.
21 lbs should last you a bit! good luck!
