Do I need to buffer Plagron Coco coir?
I never used this brand before so was wondering if any one has experience with Plagron Cocos Premium. Do I need to buffer it with cal/mag before use or can I use it directly from the bag?

Durban poison in soil
I have Durban Poison coming on Monday and after buying them, I did some research (dumb I know). Don't have the time for a hydro set up. Will it still do good in soil and are there any tips for growing in soil?

PhUp P.Hydro vs. P.Carb vs. Both
Potassium Hydroxide Vs. Potassium Carbonate : or Both for PH+ up. Does one have lower EC value in solution when used? Does ones have better stability in solution for hydro or soil? Does one have more reactivity with other elements in the grow? Does one have higher PH? Cheers,

DWC air pump
Anyone with previous experience, what's the minimum/optimum size pump for my air bubbler? I have a cheapo single line pump, I'm assuming it's enough but not optimum. Can anyone put a number on it in cfm? Is more always better? At what point do you reach diminishing returns?

I am germinating my seeds in coco. My coco shows PH of 4.5! That seems way too low! I tried to flushing with PH 6.7 water without any effect (see growdiary for more info). What should I do? Is something wrong with my coco?

Favorite Soil - Similar to Happy Frog Potting Soil
Favorite soil? Right now I am using Happy Frog potting soil in 5 gal fabric pots. I ran out of soil and need more for the last 2 of my 5 plants. Does anyone suggest a specific soil they prefer similar to happy frog? Best feeding schedule and method - top-dress or through water?

Too much soil?
I have 15L (4gal) fabric pots. The bag of soil contained 50L (13gal). It took me 1 bag and a quarter to fill 3 pots up untill the stitching. Am I doing something wrong? Could be that it has now more fertilizers in it than supposed to. Thank you

Fill up plant pots
I mounded the soil around the stems of my plants to give them extra support, which creates a small hill in the center of the pot. Now I’m thinking about filling up the rest of the pot with soil to level it out. Is that a good idea? And what type of soil would be best for it?

Did I need to size up to larger rockwool cubes?
Geminated seeds in 1x1x1 rockwool cubes. End state is to be in 5 gallon buckets with 8" net pot and clay pebbles. I figured the roots are too small to reach all the way into water solution still so put small cubes into 4x4x4 rockwool. Did I need to use larger cubes?
