Girl Scout Cookies Shed Grow

Well it's been an interesting grow week that's for sure. Day 1 of flowering I set my lights to 12 hours and then I go an notice tiny webs on my fan. Spider mites maybe? Well I sprayed just to be sure and will again tomorrow and the week after just in case. I guess this grow is in an outdoor tin shed and spiders of the bigger variety have also been an issue. I did let a insect bomb off b4 I started but the little things always find a way in. I just can't be sure either way what the cause was. With the lighting schedule I decided to set my lights for dark hours from 4:30am to 4:30pm and lights on over the night. Sounded like a good idea to start with but all of a sudden cold nights followed, 9 degrees c then 2 nights of 8 then a super cold one at 7 degrees. Tin shed = zero insulation🙁 Now my heating bars do a wonderful job but with lights on and the bars on full I could only get the tent temp to around 18 degrees. With the moist night air and the heating bars cranked up also brought condensation in the tent. Man growing indoors would be way easier but impossible for me. Well 18c is way too cold for lights on so what can I do? Well drastic times require drastic measures and I had no choice but to flip the lights. To do so I did 12 hours dark, 1.5 hours light then back to 12 hours dark. This effectively brings my lights on from 6am to 6pm and off of a night. Hopefully by maintaining a higher temp when it's lights on and lower temps when lights are off will give me better results in the long run. I will still keep the heating bars going of a night but at reduced capacity, which hopefully reduces condensation. On top of that feeds will occur at the start of the day when the lights first go on, less water in the coco coir has to help with the cold nights. I was also running low on space in my tent. I had to bring a fan down beneath the canopy for airflow and the only way to do was to either sacrifice a plant or seriously cut back a plant. I went for the later and the fan fits like a glove. I also think I need to turn down the heater for night hours because they are on so much now keeping things warm, in particular without the additional heating help from the lights. I think the new growth is impacted. One leaf I noticed today in the centre above the heaters was all shrivelled. Will monitored and adjust as needed. Hoping for my scrog net to arrive in the next day and fingers crossed that helps even more as it will allow me to create some space where needed. So yeah, a rocky road it was this week. I'm hoping all has come out unscathed with minimal impact. Guess I'll see how things progress over the next few days. Either way they are looking healthy still and with any luck things really kick on over the next week
