Liberty Haze - organic - living soil - SCROG - 60x60 - single Strain

This is my 5th grow cycle and the first time I gonna use SCROG method. On the picture you can still see 2 plants. One will be removed later on due to yellow and abnormal leaves (it was Durban). So I decided to continue with just 1 plant in my 60x60 grow box. So Liberty Haze, let‘s get started. Germination was done by 18h of watering the seed, put it into a Jiffeys, and placed the Jiffeys into a 7x7 container filled with seedlings soil. Keeping it moist not wet! I also placed the seedlings on a box filled with moist clay to increase the humidity. SanLight at 22% during seedling stage (~200 µmol)

- Applied one time Greenhouse Feedings Hybrids fertilizer at the beginning of week 2 - rest of grow is purely organic

- re-potted into 2l pot - added 7g Greenhouse Feedings BioGrow as topping - water: 70 % Reverse osmosis + 30% tap water - poured with GreenHouse Feeding Enhancer (every 2nd week) - placed the first moist sensor into the soil (the little black box) My Soil: 50% LightMix (already contains an amount of wurmcasting and perlite) 20% Cocos 15% Perlite 10% Wurmcasting 5% Bokashi (compost) 60g dolomitlime/10l make it moist and let it mature for at least 10 days

The plant is doing very well. She looks very green and healthy. It seems that the organics are starting to work. The Geek part: My watering system is based on a Gardena water pump that I can control remotely. I measure the soil moisture on a 24/7 basis with my DIY sensor and store its values into a Influx database and use Grafana to visualize these data. That way I can look after my plants even if I'm not at home for a few days. If you want to automate your grow in that way as well I can highly recommend to use Home Assistant in combination with InfluxDB, Grafana, and NodeRed plugins.

- Top cutted - Repotted into final 12l pot - SanLight 33% to 50% during that week - last week before flowering

After 5 weeks in vegetativ state I switched to flowering state. The plant indicates that she is ready by showing the first female pre-flowers. I added 30g of Green House Feeding BioBloom as top dressing. The lights are switched on during the night (9:15pm-9:15am) to keep the canopy temperature as cool as possible. I also increased my SanLight from 50% to 66% to keep up with the DLI to limit the expected stretch of the plant (that's my theory).

Wow.. I see a clear response towards flowering just after one week. Installed the SCROG net and did a first defoliation at the end of week 2. In addition I applied 2l compost tea to the plant . - 1 cup worm casting, 1/2 cup bokashi, 1/2 tea-spoon melassis - let is bubble (air stone) for 12-18 hours

I applied another 10g of BioBoom as top dressing at week 3 to adhere to the recommendations of a 10-week flowering schedule. Increased SanLight to 75% and applied another compost tea at the end of week 3.

SanLight is now at 80%. Applied another compost tea and a BioEnhancer solution. OMG: I put too much pressure on my 2 main branches to that I split/crack my stem! Let's see how the plant will react on that.

Not much to do during this week. Increased SanLight to 90% (~37 DLI) and applied the weekly compost tea. I'm aiming for higher temperatures during mid flowering and to cool down in late flowering and ripening stages. Leaves are turning a little yellowish. May be as a response of the cracked stem.

SanLight is still at 90% with a distance of 45cm to the canopy. I would say we are currently at the peak of the flowering production. The EC and pH level refer to my pouring water. Nutrition is based on Greenhouse Feedings schedule (lower limits) for BioGrow, BioBloom and Enhancer. Lower limits are taken into account because I already enriched the soil with compost (Bokashi and worm compost) and I feed with compost tea once a week to ensure a healthy and microbe-active soil. Drain water is at 1400ppm (500 scale).

- added a little Calcium to feeding water (125ppm) - reduced light to 85% to cool down the canopy. The goal is 24-25°C during the final 2-3 weeks

The smell is getting stronger. We are entering the final 2 weeks. Used 2 l of Enhancer solution for the last time. SanLight down to 80%

Day 57 in flowering state. I increased the lamp by another 5cm to lower canopy temperatures. My main focus is on low canopy temperature to archive the best terpen profile possible regarding my environment. SanLight will be adjusted between 80-90% based on temperature. Currently at 90%. I also extended the lights on interval by 30 minutes to keep my DLI as high as possible (from 12/12 to 12.5/11.5). From now on I only water with purified water EC 0,1 (80-90% RO water + Tap water)

Day 57-64 Last week I increased the lights on interval by 60 minutes. This week I decreased the Interval by 120 minutes so that I have now 12.5 hours of darkness and 11.5 hours of light (to speed up ripening). Leaves start turning yellow. Most trichomes are transparent very little trichomes are brown. Further readings indicate to harvest around 70+ days. The over all weather condition seems to be beneficial to the plants. We have cool nights 8-12°C (my lights on) and not too hot days 18-23°C (lights off). I was able to maintain canopy temperature around 23.0°C 47%H.

I curious about the different effect of early and late harvest. So I gave that strain another week of ripening. Just feeding with purified water (80% RO + 20% tap water). One cola seems to have an issue. The sugar leaves turned grey very quickly. I'm not at home during the week so there is nothing that I can do remotely.

Early to mid harvest at day 66: I cut off 1 of my 4 branches. 150g of heavy and massive flowers full of trichomes. Some of them sparkling in the light. Day 70 harvest: Cut 110g a little more sparkling flowers. Day 77 harvest: The top of one main cola was affected by bud rot. Fortunately the only occurrence. No other bud was affected. Finally I harvested 400g of sparkling and healthy flowers. 660g of wet dense buds in total.
