Documentation day 29 - 35, 2nd week of flowering
Exposure time: 12 hours daily
Ø PPFDe 500µmol/m²/s
DLI 21,6mol/m²/s
Temperature: 26°C Room humidity: 65%.
The light intensity was increased from 500µmol/m²/s to 80% power of the lights.
Tent No. 3, EVO 4-120 to 80% ~650µmol/m²/s.
The plants are now in a strong elongation phase and the nodal spacing is starting to lengthen noticeably. Growth is still very satisfactory.
The plants are developing vigorously and no longer show signs of over-fertilization.
The plants get a daily water amount of 900ml per day and plant.
Watered with a light fertilizer solution of 1.4 EC at a pH of 6.2.
Try shoring up those temp fluctuations between lights on and lights off. More than 10 degrees less when the lights are off before their done growing vertically will give us a lot of unwanted stretch. Once that vertical growth is done we want to then open up that temp gap to stress them out and signal them to put extra energy into the budding process and resin production. The more we baby them and keep those temp gaps close through veg & early flower it will have a much more explosive impact when we want it to.
Nice tent man, If you do not have them already get yourself a thermal laser temp gun & PAR meter to better read your plant tops. Those lights should be closer to be getting as much PAR onto those plants as they can take. Keep up the good work, Check out my 200 light 7,000 plant diary & follow my profile and youtube for videos!
@sanlight, Sounds interesting, Considering your plants are extremely stretched towards the apex colas. I looked back at your temps. Your stretch is coming from opening up your temp gaps too early in flower to more than 10 degrees less with lights off. At week 4 that strain must have still had vertical growth to complete and that temp gap stretched them for sure. I also looked closely at your photos I do not see any sun grip light pullys to raise & lower your lights do you utilize these? They help a lot. Just trying to help friend! We do not want to waste energy and resources growing stem & having giant node gaps like that its power, food, time wasted.
Happy Growing!
@LegacyMarketFarm, thank you for you comment. The purpose of this tent was NOT to have the fixtures at full power. And yes we have spectrometers and laser temp guns. =)
