Yea, that is something along the lines I've used when I had the Maxigro and Maxibloom. I think I put both of those in some ratio to come close to that NPK 3-1-4 with CaMg 2-1 type of ratio. But I remember having slight Ca deficiencies before the plant grew better roots. I blame that mostly on...

I've read probably the N/P research paper once upon a time and that was probably the inspiration for me to try heavier N to P ratios. But as said they didn't really work out as advertised. As for this research the part I bolded is what I'm sort of thinking aswell. So pretty high limit for the K...

My numbers are based on elemental ppms, not the P2O5 and K2O.

K:Ca:Mg absorption is very connected to each other. Too much of any of the 3, reduces uptake of the other 2. And while K and Mg can redistribute themselves well within the plant, calcium will not move well. Also calcium uptake is mostly affected by the transpiration.

Few years back I tried some NPK levels which were from similar researches. The 5:1:5,5 NPK, which is something like Maxigro, has way too much N and K. I'd get N toxicity and Ca deficiency (likely due to excess K). Though the plant uses less N and more of P,Ca very early in veg while focus is on...

When talking about sun as comparison for light, one should always remember how different the spectrum radiation is around the world. Time of year, altitude etc.

Yep. While vegging you could even have 1:1 K:Ca since the plant needs more calcium at that point. @ifoodhippie overdoing any of the K,Ca,Mg will lead the other two absorbing less. So always think that too when starting to see one of them being deficient. Make sure you are not giving too much...

His brain has gotten bad case of microwave radiation, likely from the LED he was using. But forgive him brothers, for he doesn't know what he's talking about.

@ 150W your LED should produce close to same amount of light than the 250W HPS. So around 3/4 of max power? Have you checked out the Photone app for measuring the amount of light? It's pretty handy for getting an idea how much light you are throwing at it.

Sometimes, they crack open and wither from various reasons. But if only some days behind the other feller, I'd still have high hopes for it grow. Maybe you could pop a backup seed and if you end up lucky you'd go with 3 pots? Careful with watering at this stage, wet is the enemy. Any sort of...

Looks about right, I don't personally have experience with Spider Farmers. But alot of ppl here has them and seem to be ok.

250W HPS produces around 1.7 umol/W, so ~425 umol/s Most of the LEDs produce ~2.5 umol/W, so with 180W you'd get pretty much same amount of light. So look for LED that has around 450-600umol/s. which would be around 200W.

No, use existing app, like the Home Assistant to control the devices. You'd just build the algo how the Home Assistant would control the setup. Just need a device where to run the app. Then connect to it from PC/phone through webpage

Advanced Cannatrol Logic Features (and How to Mimic Them) 1. Dew Point-Based Control Cannatrol doesn’t control just RH — it controls dew point, because that reflects the actual water vapor content in the air, which affects drying/curing more directly than RH alone. DIY mimic...

Gotcha, so the default Tuya app in the smart switch you linked isn't enough?
