White Widow (Canuk Seeds) DWC

2020-05-14 New week who dis? As you can see, a new light from Phlizon arrived today that completely destroys the blurple light I had been using. I realized my plants would never get to their full potential with that lower powered light. It is ok for veg but not big buds. This one is perfect for 2 plants as it is long enough to be directly over both buckets simultaneously. People say that it's best for 1.5' x 3' which is basically going to cover my plants fairly well. So excited but I have been toying with the air flow because the light has added about 5 degrees F to the tent... gonna have to make sure I'm not drying the plants out but so far my numbers are ok but fluctuate too much. I used the dimmer available on the driver to reduce the light intensity to its lowest while it's still in early vegetative. Wish I had a PAR meter but I don't have that kind of money. 2020-05-15 I was trying to balance fan blowing/humidifier running by alternating cycles but it was too swingy, I decided to try to find a combo that I could run non-stop even if it was costly on distilled water for the vaporizer. I bought my own distiller so water hasn't been too much of an issue but still a lot of energy usage. My tent was undergoing a LOT of negative pressure to the point where the walls were sucking inwards and knocking things over.. I realized I had to change this.. Pictured is the 'cross breeze' setup I designed. The humidifier blows vapor constantly over the 2 buckets. The fan is in the left corner blowing cold air into the top of the tent; the vent next to the fan is half open to allow more passive airflow. The carbon filter is in the top right, and the exhaust fan is 190 CFM sitting outside in a "soundproof" plastic tote. Seems to be working. I will edit when today's light cycle is done and see how it is! 2020-05-16 Still trying to nail the humidity and air flow... I definitely need a fan speed controller. Plants are clearly happy thoug. I have lowered the water in the buckets to encourage the roots to grow towards it! Gonna make them chase it. They aren't drinking enough to change the pH or the nutrients yet. Still gonna give them fresh nutes soon anyways! 2020-05-17 Roots are growing at an insane rate!! Plants looking super healthy but they aren't drinking enough to change the nutes in the bucket. Going to give fresh nutes tomorrow anyways so that Monday is always the nute change day. 2020-05-18 Took some nice pics! Seedling 02 hasn't shown any further damage to its leaves at all.. I really wonder what happened. It definitely slowed down a bit. It's still technically 2 days behind which really shows in the foliage but the root structure is already looking awesome, preparing for some explosive growth. 2020-05-19 Seedling 02 is recovering nicely, finally started working on another node. Seedling 01 is BOOMING, closing in on its 5th node, it's almost time to top it already!! The plant is now drinking but wasn't taking up nutrients. I had soaked the hydroton in the same amount of nutrients for 24 hours prior to transplanting the rock wool. That alone could have sustained the plants for a while. The EC/ppm started at around 450 but actually has gone up to 510. I realized this meant that the plant was drinking but not taking up nutrients. I monitored it again 8 hours later and the ppm was back down. The TDS meter is perfectly calibrated so no issues there. I will carefully monitor and try to maintain ppm concentration as the plant drinks. I also need to monitor the water level! I haven't added any because it didn't change at all because the plants roots just descended like 72 hours ago. I have only actually lowered the water level to just below the net pot. Will monitor all the things to keep this going strong. The roots are growing by the hour. It's hard not to keep looking at them all the time. 2020-05-20 Just topped the first seedling and the 2nd one is close behind! So far, the plant is drinking and the pH and ppm are very slowly creeping up. Gonna post a question. I think I might need to top it up with fresh water and pH it again.
