2/6/24 - Veg Week 1 Day 1 - Flush and fill day. Drained system completely and wiped all down. Added 15 gallons of fresh RO water. Added Week 1 nutrients. Will allow system to recirculate for 24 hours and then make any pH adjustments. Plants are looking great! PPFD is at ~280 measured with Photone App with diffuser.
2/7/24 - Veg Week 1 Day 2 - pH adjustment day. Unfortunately, I had a huge discrepancy between my two main pH meters. Thankfully I have a total of 4 meters. I re-calibrated all of them and got the solution as close to 5.89 as possible. I have ordered a 5th pH pen and will make sure it is dialed in. The good news is that it is definitely between 5.5-6.5 so the plants continue to thrive.
2/8/24 - Veg Week 1 Day 3 - adjusted pH again to bring it back down to 5.89. Tent environment and lung room have been pretty stable and I'm maintaining the VPD at 0.8 - 1.0 kPa
2/9/24 - Veg Week 1 Day 4 - So, I realized last night that my PPFD had been way too low for the last few days which was causing an undesired stretch. I use the Photone app with the Lightray diffuser for measuring PPFD. Apparently, I forgot to change the setting in the app for the diffuser. I corrected my error and hopefully all will be well. I added some more Silica to the reservoir to help bulk up the stems. Adjusted the pH back down to 5.90. Plant growth looks good.
2/10/24 - Veg Week 1 Day 5 - More roots in the water. Adjusted pH back down to 5.89. Plants still growing nicely.
2/11/24 - Veg Week 1 Day 6 - pH is steady at 5.89. Checked PPFD at top of plants and we're sitting at 275. All is looking good
2/12/24 - Veg Week 1 Day 7 - Final day of Week 1. pH is still stable at 5.89 Double checked the light distance from the top of the plants (18 inches). Got some pictures of the roots in the water.
I’m looking at building the same system (PAHydro) once I get set up and dial my tent in with a basic living soil grow. Just to get a feel of the tent. After that of the the RDWC races. Will be follow for sure much love and thanks for sharing your j
