Blueberry OG in Coco + NFT

@NegotiatedBubble, Thank you! Will try my best to keep it updated well.

@Tremojem, you’re welcome 😉 Nice to meet someone with the same level of dedication to growing!

@@Mr_Incognito, I cannot thank you enough for the complete and concise response. Very good information there. It leads me down a path that includes more research for me. I am always trying to learn even if I have no intention on pursuing that or any path. All of the information is, in some small way, related and there are bits that overlap and that leads to more understanding of the BIG picture and helps in preparing for a better and more successful grow. I am truly interested in Coco, Hydro and Living Soil. But as you move into those three areas of growing methodology you invite more opportunities for errors unless you know what your doing. So it is best to take baby steps, research, discuss and learn, then step/repeat the aforementioned steps in an effort to prepare yourself for the journey with intent on success. But if growing in soil has any benefit, it is that it sparks your interest in always improving and doing better. Thank you again, and I will be following you. I cannot wait to start a drip system as it has been forward in my thoughts for some time along with Autopot. Good on you for knowing what a drip rate is. I have interest in a drip system that utilizes gravity for feed and switching timers for cycling. Multiple cycles at the rate I choose. Love this stuff. Be healthy and happy Brother.

@Tremojem, thanks for asking :) I started my first diary with quick auto, soil and pH perfect nutes because I was very short on time. Also I wanted to restore some of my knowledge and experience from the past. Just to get some yield of good looking buds, no matter what is the strain. It was a magical experience, so many busy days and nights, and extreme challenge with security. Luckily all went perfect, and the buds were amazing despite of the claimed low-level THC. Excellent smoke. Then I got a possibility to make another grow where I chose to go 4 plants at once. I couldn't find fabric pots, that's why I chose airpots. They were good, although I had difficulties with focusing well on the growing process. My latest grow is Coco/Perlite 60/40. This time I wanted to go hydroponics in rockwool as I did long time ago. Unfortunately horticultural slabs were not available and the only option left for me to go pure hydro was coco. So: 1) Coco/Perlite Mix 60/40 % 2) Drip watering system. First I started with Arduino-based irrigation system with a cheap pump from Aliexpress and solid state relay. It worked well until the pump died unexpectedly (hahaha). I was struggling with the same model replacement one, but luckily I got Kamoer X1, and I'm really happy with it. 3) I collect runoff in the plastic container. Was trying hard to collect it almost every watering to react quicly if something goes wrong. Last week I changed my mind, just to have some rest. I made a DIY Coco slab, that is often used in commercial grows. The cover is used to retain water, the same as with rockwool. Such porous substrates are drying out too fast. I really don't like salt buildup in any kind of substrate. Less or none flushing needed during the whole grow in this case. The cover helps to keep coco/perlite mix evenly moist. The tubes end with small T-shape splitters and are lying on the substrate, just touching it. There's no issue with water distribution in coco with low speed flow. To help water distribute even better I intentially reduced the number and the size of drainage holes. They are made right in the corners of the container at 45 degrees angle, just 4-5 mm diameter. The solution retains longer and runoff is pretty slow. That helps to wash out any salt build up. Fast drainage would be less effective. With 48 ml/min flow rate it works even better, but probably there is higher loss of water during runoff collecting because of evaporation. I put the slab on the set of tube pieces to position the center of the slab a bit higher than sides. The same method is often used with rockwool in horticulture, but there special W-shape trays are used for that. I surely miscalculated few things like the volume of the substrate. I'm using just 8 litres of mix. Didn't expect to stay in Veg for so long, but now I'm very happy that I let her grow for so long. I spent a lot of time trying to catch the ideal spot between inflow and runoff. Was underfeeding her for long. Reduced Nitrogen levels from week 2 of Veg, because it seemed to me that I noticed some toxicity signs. Later I discovered lots of sediment in the Grow component. Probably it made NPK ratio wrong from the very beginning. Well, even with less N she performed really well in Veg. Now she's in perfect spot. Inflow is a little bit higher than runoff, and the gap is reducing. Runoff percentage is 12-15 % at the moment. WIll increase when runoff EC goes higher than inflow. Before that I will just play with inflow EC. She's a heavy feeder with pure Indica appetite :) She handles EC 2.3 easily and drinks more and more as the stretching continues. Probably she will hit 4 litres per day soon in 24-25 degrees and 55% relative humidity (VPD 1.31-1.39). I use a lot of hydrogen peroxide to treat algae near the drainage holes. A bit worried about the taste in the future, but not much :) Will flush it one week before harvest.

@Maryjane23, thank you! Hopefully will get to the finish with no issues🤞

@Tremojem, Thanks dude! Data processing really helps me to understand and witness the progress since I have some scientific background. I'm keen on visualizing data. Surely some growers will say it's nonesence. I don't mind :) My goal is to make the process fully visible, tracking all important factors that have impact on the grow. Helping someone else to understand plant's behaviour and lifecycle makes me happy. I would love to contribute to the growing society and help people to see what's hidden behind the scene. Lots of important things are often missed, and as a result people (including me) sometimes read plants wrong way, thus making wrong decisions.

@Cannapopz, thank you 😊
