    Nute Water vs Plain Water Replacement

    I'm growing in DWC with 5 gallon bubblers. My biggest girl will easily drink a quart/day. My goal is to maintain EC right around 2.0 (1000 to 1100 ppm with a .5 conversion) and pH between 5.2 and 5.8. I check pH twice daily at the beginning and end of lights on and adjust appropriately. Like...

    Debatable question time #1

    Hey Celt. If you go back to the OP's first post he specifically asked if root cells were capable of absorbing water without nutrients and by logical extension if they can also absorb nutrients without absorbing the water they are dissolved in. He further went on say he wanted to believe plants...

    Debatable question time #1

    Osmosis is only part of the answer. Osmosis is the process responsible for bulk transport of solutes scross a membrane, but the cell membrane, or plasmalemma is differentially permeable to both water (the solvent) and nutrients (solutes.) This means it has the ability to control what is...

    Mars-Hydro LED Grow Light Discussion

    Kudos Sarah! I AM from the U.S. and I did read it the way Sarah did. Sorry Gnarl E, I DO think he was disparaging all Asian cultures (as if there is one single "Asian" mentality). Sarah don't you dare apologize for what you said. It needed to be sai and said quite eloquently. Even if the slight...

    DWC: Quick question about pH and ppm

    Thanks for the comment OldMedUser, but honestly I don't see how I'm doing more work. I don't make or have to buy RO, I don't use a chiller but have no root rot problems even though bucket temps are running 70 to 72 F right now with the warm spell we are having. I have an oversized air pump and...

    DWC: Quick question about pH and ppm

    I have two (Chem Dog) girls flowering with one a week or two from harvest in DWC bubblers (no reservoir.) While the plants are young and vegetating, I think the weekly nute change simply puts money in the pocket of the nutrient manufacturer. You can easily stretch it out to two or three weeks...

    Mars-Hydro LED Grow Light Discussion

    In my experience it's very possible. Since LED's don't produce much radiant heat from the lamps, the "don't burn the back of your hand at the topmost leaves" rule of thumb doesn't work. LED's produce heat but most of it comes from the heat sink protecting the PCB's/chips and with my units is...
