Hello and welcome to week 3 of this Diary 🙌🏼, Last week I had a little mess while transplanting but the girls seem to be thriving. It‘s day 12 since they came out and i‘m impressed how they are growing already with low humidity and a DLI of around 25 so i think they‘ve arrived at the Vegetationsphase. I would love to push them harder but I don‘t have a real CO2 system in place. You see, my lamp gets really hot at 100% and Plants have something called „photorespiration“ when the leaves get too hot. They confuse CO2 with oxigen and use up energy whith the wrong „gas“. So the optimal temperature shifts when C02 ist added. Not to mention you get up to 30% more yield. I already got some things from amazon delivered to me next week so if you want to follow along you can see me attempt to put it in place and hopefully make it work. I‘m planing to make the whole growspace airtight (but still excesseble) and build my own coolingsystem and dehydration system WIHTHOUT getting new air in to prevent the CO2 from comming out. I think I will finish it by friday and post an update. I will keep it short this time and hope you have a great day, growmies 👍🏻 Update: the Co2 system is in place and it seems that just by making the space Air tight, the CO2 bag in it is enough to highten the CO2 in the tent to 1130! And it‘s still going up. It‘s now actually pretty hard to get it out 😭 I have to rethink the temperature settings because now they can take it. I read that they can take up too 3000 ppm Co2 but we‘ll see. My lights aren‘t that strong and imm not getting a new one. Very important to keep the tent cool and dehydrated tho without etting rid of the CO2 so I bought 6 packeges of dehydrating subrtate in bags and a cooling system wich dehydrates too obviously. I also bought a CO2 reactor, wich can be refilled. It‘s a reaction based off of 700 grams of bakingsoda and 700 grams of Citric acid (it‘s ment for aquariums but who cares). The CO2 device sets a target and shuts on and off when it‘s off by 1/2 of the Zone I chose. It detects when the light turn off and shuts down too. Rn it‘s not even turning on because of the CO2 bag. So if you have one of those, can make your tent Air toght and you can build yourself a cooling sytem you could have a high Co2 tent with less than 100€$. But since one Exhale bag is pretty expensive I figgured investing in a reactor such as this is much cheaper in the long run. The CO2 controller was epensive tho. Tomorrow i‘m feeding the plants again 1100 EC this time (it‘s been 2 days) and i‘m going to keep posting updates. C ya soon 👌🏻 Update: since day 15 i have the tent in 800 ppm CO2, 30°C, ≈50% humidity, 25.000 Lux (≈600ppfd).
