Versize First time posting on growdiaries. Thoroughly excited. This is my second grow. But I would.say my first grow was a real success so eager to try this next one.
I'm in week 5 already and will write up more weeks the next evenings.
Jack Herer was my favourite strain when I started smoking about 15 years ago. So I probably never have had real Sensi Jack. But I sure remeber a very typical Hazey taste with a lot of pine and lime. So this will be a nostalgic grow for me.
I have heard all the bad things about Sensi, but this is the closest to OG Jack I hope. But there sure aren't a lot of finished diaries on this one. I'll be hoping to add at least one.

Versize Week 1 veg. Steadily growing. Giving small amounts of water daily. The 2 small pots are in the grow cabinet I made. The heater turns on with the GGS system if it gets to chilly. Very chilly weather for beginning of summer. Lots of humidity though. So that's nice for this phase.
In the tent next to it this is less desirable where the autoflowers are finishing out and we want low humidity.

Versize These ladies are starting fast. Incredible growth for just 7 days.
Transplant in the 3 liter pot went smooth. Always using Great White. No nutrients in the water. Just CalMag and Power roots to get to about 200 ppm in RO. I then gave them a whole bunch of water before leaving for the weekend to experience Mary Jane Berlin. Was definitely awesome. Risky move with the water, but had to (I thought). So I basically soaked the soil and also put the pots on plates with water on it. Well, that paid off. The plants looked great when I returned 4 days later. But the soil was still quite wet. 😅 You live and you learn. Topped at the end of this week.

Versize I didn't take many photos this week, I see. The photos are from the beginning of the week. The photos in the next diary are almost seven days later.
I also saw in the photos that I think I already topped it off at the end of week 4. The plant is recovering well from this this week. Growth is steady!
So I'll add some photos of some outdoor plants that I'm also growing this year. They're in local compost, mixed with worm castings and some supermix. I never water them. They're very close to the groundwater there.

Versize Training is in full flow now. Being in the tent daily. Bending. Twisting. Taking some leaves sometimes. Watering every 2/3 days. The Plagron Terra Grow soil - I find - holds to much water. The 20 Liter pots often need 4 liters to get proper runoff. I also find runoff to be way to high already but maybe that's because I didn't water to runoff the first week in the big pot. Definitely will keep giving low notes with proper runoff till that is in check.
Definitely cool and wet lately so I have been running the dehumidifier in veg. 😅 Helps bring up temp in the lung room.

Versize After topping all the outer main branches one more time I leave the Training for what it is now. Maybe already regret training it a bit too much. Constantly see that my plants are very short. But have gotten great yield per square meter on the laat grow so height isn't everything of course. The next one or maybe two weeks I will give the plants some time to grow all the shoots up, before flipping it to 12/12.

Versize I have honestly learned my lesson. I have officially trained to much. Feel very silly. Now I am doing daily defoliations and also cutting out branches that aren't going to make it to the top, but also are just in excess. I counted over 36 colas per plant, so 72 colas in a 2 by 4 tent.
So in this 7 days I switched to 12/12. The Jack Herer has definitely begun her infamous stretch now. Growing over 2 cm in height per day now. Bud sites are appearing all over.

Versize Was away on vacation this week. Luckily got some help this week. Plants drink a incredible amount. I don't have much experience but I feel like the Plagron Growmix almost holds water too well. Giving 6 liters (per pot) every 2 days now.
Removed some branches.

Versize Very hot end of the week. Running the dehumidifier and airconditioning over 12 hours a day. Definitely have never used as much energy in one week. Don't even want to know. Over 15 kWh's a day for sure.
I did another defoliation and also removed even more branches. Also did a sort of bud lollipop and took ook everything that was still under the net. Some small buds and some leaves that were sill there. Also had to do this earlier. But this is a learning process. The plants are really stretching now. Buds are forming with many quite long white hairs on both.
Also start to notice the differences between the two pheno's. The left plant doesn't need as much nutrients as the right one. Also the one on the right has to dark leaves. Very green, almost a little blueish.
I definitely did way to much plant training. I have now learned that doesn't reward you with anything other than wasted time, and effort.
I'm struggling a LOT with humidity. Also in normal weeks. My exhaust fan is running 24/7 and the dehumidifier is also running quite a bit. That does work (a bit) but I fear that'll be to hot when entering the later weeks of flower. Definitely the biggest struggle in sea climate part of Europe. Low outdoor humidity over here is 55%, and basically every night 100%. On average RH outside is over 65% during the day.

Versize These ladies are really starting to look very nice and getting more smell now. I can't say it's very distinct yet, but quite the smell when you open the tent.
I have to say, the canopy looks awesome. I will do the occasional small defoliation of about 10 leaves on the 2 plants in total. I am also starting to see signs of windburn on the plants but moving air though out the whole plant is how I prevented all mold in my last grow when I didn't even have the dehumidifier yet. I have even ordered 2 more clipfans to cool my light in my other grow cabinet and 1 for under the plants in this tent.
Started with the Green Sensation this week 💚
So far I haven't really tried other brands, but the simplicity and effectiveness of all Plagron products is great.

These ladies are stacking big time!
