Purple Kush

Hi and welcome to a new grow :) Unfortunately I have to start over because of a malfunction I had with the automation of the heater. I basically cooked my plants. But now we‘re back with three new Ladys, wich I hope will turn out as beautiful as in the picture. I planted four, just in case one of them doen‘t make it. I will choose the 3 faster ones of course. The medium I use is mixed with soilles media (peat ,vermiculite) with additives. It‘s basically sythetic but it still has microbes. The nutriensolution is also mixed syntheticaly. I‘m not going to explain everything right now but at this stage i‘m feeding the plant low amounts of the Veg formular that was recomended in different studies. The EC is about 1350. PH of the Media and the Water is about 5.8. I also have a CO2 bag but unfortunately it was cooked by my heater 😬let‘s hope the funghi survived. Since oxigen is very important for the roots I am pumping Air throught the watercontainer. It helps keeping it clean as well. I do have Hidrogen Peroxide as well, but i‘m not sure if i should use it for the extra oxigen. If any of you have experience with it feel free to comment! I will keep you updated on the plantgroth over the week but for now everything is setup. Have a nice Weekend 🌱 Update: The first three girls are coming out pretty fast. InicuallyI though the 4th seedling didn‘t make it but she came out a day later. that was part of the planing so we’ll see. The first three are roughly the same age too wich is awesome. Right now i‘m giving them around 200 ppfd/24h. The Temperature and humidity are stable at 26°C and 90% humidity (as in picture) now it‘s lowered to 75% wich means the VPD is roughly 8,5. Let‘s hope I don‘t cook them this time 🙏 Oh and the CO2 bag is alive. Update: I‘m experimenting with VPD and I figured out, that the leaf experiences a different VPD due to cooling of the leaf while water is transpiring. So with LEDs the leaves don‘t warm up from the missing infra red but luckily my Light gets pretty warm so i put it up hight and brighten it to 40%. The seedlings stopped growing at a Lux of 8000 so i put them on 13000 with a leaf VPD of 0,6. I used a VPD calculater and have the following environment: 27,5°C and 60% Humidity. The leafs are ≈24 degrees (if i measured correctly) and the caculator spits out 0,6-0,8 wich would be ideal. Let‘s see how they grow since they are seedlings i‘m not sure if this stresses them. If you have any comment, please feel free to wright is down so i can adjust if necessary.
