GROW DAY 15
(day 1 of wk 3)
Watered today with 0,4l/plant after having a break from watering for three days. Continued with Root Juice and Heaven, but added 1ml/l Grow into the mix. Continued spraying with water and poured some on the bottom of the tent to add some moisture.
New growth seems fine and the heat stress which I noticed earlier seems under control.
After pumping the plants full of water in the morning, I ended up doing some LST late afternoon. Intresting to see tomorrow how they react.
GROW DAY 17
(day 3 of wk 3)
Last week I decided that HID era was ending for me and I placed an order for HLG 550 V2 R-Spec -light. When changing the HID lamp for the LED, I witnessed first hand the fact how temperature really affects the light intensity of a HID. I had a cooltube on the lamp with an extractor pulling around 16C cool air through the tube. When I started taking the lamp down, I shut down the extractor and the lamp got quite a lot brighter:)
After the relatively easy installation, I couldn't be happier with the HLG 550. I spent over a week reading up on different lighting techniques, photosyntesis and all things related to how light and especially cannabis plants work together. After this I did some vigorious comparison of different options and ended up with the HLG 550. I´m not saying it´s the one and only, but seems to be a perfect match for my current growing situation.
I started off with the LED hanging 60 cm from the plants, but after a couple of days, raised it to 75cm as I still noticed some heat stress signs. Had to realign my fan and the extractor tube as they were giving the plants hard time as I noticed some clawing leaves. I figured this was wind stress and the symptoms disappeared after realigning the air so I guess that was it.
I decided to give the plants a break from LST for a couple of days as can be seen from the pictures.
GROW DAY 19
(day 5 of wk 3)
Added couple of pictures of the new setup with the HLG 550 and reworked airflow.
Continued with the LST today and I'd say it´s working nicely.
Increased watering after 4 days break. Gave 0,6l for each plant. Increased Grow and Heaven dosage for this watering, left Root-Juice out and added Bloom and Top-Max to the mix. The plants seems to be reacting favorably.
