Harvest
The day before harvest, the plants were no longer watered, in order to deprive the flowers of as much water as possible.
On the day of harvest, all large fan leaves were removed from the plants still standing.
After removing the fan leaves, the plants were cut at pot height and the flowers were separated from the stem.
Subsequently, the flowers were freed from their petals and the flowers were hung to dry.
After successful flowering phase, the harvest of the hemp plants took place. The plants were first cut off whole and dried. Subsequently, the flowers were separated from the plant. The dry flowers were then trimmed by machine. Subsequently, the flowers were then finally dried at 20°C and 55% humidity. The flowers were sorted according to size (large and small flowers), and weighed.
Results
With the SANlight EVO series, exposure intensities >1.000µmol/m²/s lead to an increase in yield per area, but reduce the yield/performance ratio by up to 26%.
Further, this trial demonstrates the superior performance of our EVO-series. Even when operating the lights at only 80% of their power, yields well above 500g/m² are achievable and more than 2g of flower mass can be produced per watt.
From an economic point of view, the use of the EVO 4-120 is absolutely recommendable, and a reasonable compromise between performance and economy.
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. =)
