I'm heavily considering switching from H202 to pool shock (running sterile). Looking to gather some knowledge before taking the plunge. If I understand correctly, the measurements are 1g of shock per gallon of water to make a solution? That solution is then added at a rate of 5ml/g? I should...

Question for you hydro guys/gals using LED. What temp and RH are you guys shooting for during seedling, veg, and flower? And do you have a specific VPD range you shoot for at each stage? Please feel free to throw in any other useful tidbits of info about the rate in which you drop humidity...

Can anyone identify what this is and what's causing it? I posted this earlier under the title "calcium deficiency."" but it's definitely not a calcium issue as it's on the lowest set of leaves (first true set). For reference, this is a recirculating dwc system, rw and hydroton, using revese...

Hey all! Just started this girl on nutes a few days ago using RO water and thinking I didn't add enough Calmag (requirement with ro water). I only used 1/4 the recommended dose. Is this a calcium deficiency? If so, should I increase to 1/2 the recommended dose of calmag, or shoot for closer to...

Hey all! I'm currently dealing with conflicting info online and hoping you guys will guide me in the right direction. My question is regarding when to start adding nutes in rdwc? Some sites suggest starting once seedlings are 1-2 weeks old, while others state that to wait until cotyledons die...

Hey all! Can someone with experience running a sterile system (hydroponics) using H202 please advise me how soon I can start dosing H202? Can it be used from day one (post germination) or do I need to wait for the plants to reach a certain point in their growth? Yes, I know bennies or pool shock...

Hey all! What's your preferred method for starting germinated seeds in rockwool in dwc/rdwc without a drip feed? Do you let the water touch the bottom of the netpot with the bubbler misting the hydroton? Or keep an air gap between the water and netpots and top feed manually 2-3 tines a day? Or...

Looking for advice on how to adjust nutrient strength weekly in a rdwc system without doing a water change. Example: Week 1 use 1/4 tsp per gallon of each nutrient solution. Week 2 use 1/2 tsp per gallon. Does this mean for week 2 I would add another 1/2 tsp per gallon to system? And if so...
