The Chronicles of Narnia, Chapter One.

Ah Lucy, there you are! :p Hello and welcome to Narnia. A little yet beautiful ecosystem, located just behind my closet doors. Indeed a wardrobe is known to be one of the best hideouts from adulted humans, as we can see in the original movie. Of course my 0,14m² are not able to generate generous yield. It´s all about the quality isn´t it anyway? So I guess "stealth wardrobe growbox" would fit aswell, but Narnia does sound more mysterious. But let´s get it on, these 3 little chics were growing happily under a ~30W China LED-Grow Light for the first week now and all of them love the 30% Perlite/70% Coco - Mixture. I flushed the Coir beforehand, using tap water, until the drain had an EC of 0,6. Please do *not* refer to my nutrient [Ml/l], because I´m not mixing my solution like that. I just take as much water as I might need and put drops of a certain ratio in(e.g. 1:1:1), until I reach my desired EC value. On day 7, I fed them with a, Micro-, Gro-, Bloom-Ratio of 1:1:1, with a fourth part of Ca+Mg, solution of EC=0,5 and PH=5,7. The Drain afterwards has had an EC of 0,65 and a PH=6.0. They reacted very fast to the nutrients, like you can see in the pictures above. Hope that they don´t get burned tho.... Has anyone got a clue about the purple-ing occoured after feeding? :)

They are still flourishing under the 30W China Light. The LED-Strip is for flower only, especially the green color. So I can stare at my plants even when their light cycle is dark. As well as to support bud development and to achieve a more blueish spectrum, while stretching (should help prevent this). I can control every fan, the led and the strip from my control panel. My maximum canopy is 0,15m². Last but not least I´m planning to solder my own 50W COB LED Grow light, pictures will follow. I´d be glad to answer some question about my setup, since building small and stealthy growboxes became kind of a hobby. For me the perfect way for everyone, at least .... everytime your Growbox has to fit in smth and should not be louder as a Gaming-PC. In case of my circumstances, that means 420/7. On day 14 I used a solution of Micro/Grow/Bloom 1:1:1 EC(IN)=0,5 EC(Out)=0,6. Higher Drain EC means that there are more Ions/Minerals in your medium than in your solution were beforehand. My new Coco contains a PH buffer that influences this measurement.So I think I don´t have to mind and it´s delta0,1 But in case you water with, for example: EC=0,5 and it comes out as EC=1, then you should probably cut the nutes. Your plant can´t handle too much nutrients and you end up, osmosis doing it´s job, with dry plants although your medium is wet. Uselessful Tip just in case you want to dry out your plants, without the absence of water: Step#1 just put as much nutrients into your solution as possible. Step#2 Success

Drain after feeding on day 20: EC=0,835; PH=6,1. Switched to 50W COB LED on Day 20 aswell. Hope #1 takes the HST, wanna try out how different techniques effects growth and yield.

This week I struggled a lot with the substrate. I use Canna Coco with 30%Perlite, but everytime I water the plants with PH 5,7, the resulting Drain ends up as high as 6,5. No matter how much I Flush. So the pufffer they are putting inside might be shit, but I can't change it anymore. My growth is slow and the leaves tiny.

Flushed troughfully with EC1.0 PH5.0. They start doing better and better everyday. #2 and #3 are already showing their first pistils. I'm starting to do LST every other day.

They are growing a lot better since I´ve got the environment under control. The Vapor Pressure Deficit (VPD) has been kept around 0.5-0.9. From now on I´m aiming at 1.0-1.3 for flowering but with my setup it´s more like 1.6 at day and 0,8 at night because of the temperature difference.... I ordered a humidity control relay to regulate my exhaust fan, but like everything else from china, it will take two decades to arrive. for everyone wondering what VPD is: http://www.just4growers.com/stream/temperature-humidity-and-c02/vapor-pressure-deficit-the-hidden-force-on-your-plants.aspx
