Germination
21d ago
cloudrider Germinated seeds directly in soil with plastic sandwich bags used as a mini greenhouse hood. Shown are several strains sprouting. These are regular seeds, so will have to pull males during flowering stage. Will start fertilizing with a compost tea once a week that consists of 1 teaspoon of Craft Blend, 10 teaspoons worm castings and 1/2 teaspoon Hi-Brix in 64 ounces water that has been left open for 2 days.

cloudrider Germinated both seeds (100%). These are regular seeds, so will have to pull males during flowering stage. Fertilizing once a week with a compost tea that consists of 1 teaspoon of Craft Blend, 10 teaspoons worm castings and 1/2 teaspoon Hi-Brix in 64 ounces water that has been left to sit for 2 days. Heavy wind from fan in grow box is essentially a Low Stress Training technique and will keep height manageable when they are moved to the grow tent.

cloudrider Plants are motoring along. Nice thick growth with short internodal length. The wind from the fan is the only Low Stress Training technique being used. Preparing for a sea of green. I am not planning on topping, will have single cola plants. Will switch to 18 hours of light with continuous 24 hours fan in grow box for another 2 to 3 weeks prior to moving to tent for flowering. Alternating the compost tea blend (with 8 drops SuperThrive per 64 ounces) and straight watering (PH balanced) approx. every 4 days. Using 2 drops PH Down for every 64 ounces of water or tea to balance PH (target of 6.5). Letting plants fully dry out prior to watering. TIP: Lift the pot to get a feel for the weight when light (dry) and heavy (wet).

cloudrider Week 3 completed, both plants are doing good. Plant 1 is 8 cm tall and is smaller than plant 2 which is 10 cm tall. Still have nice thick growth with short internodal length. Fan is on High setting and is on continuously. Wind from the fan is the only Low Stress Training technique being used. Shown is sea of green with several strains. I am not planning on topping, will have single cola plants. Switched to 18 hours of light with continuous 24 hours fan in grow box for one more week, starting to run out of head space in the grow box. Will move to tent for flowering. Alternating watering (PH balanced) approx. every 3 days with half strength compost tea blend (see prior compost tea recipe plus adding 4 drops SuperThrive per 64 ounces). Using 2 drops PH Down for every 64 ounces of water to balance PH (target of 6.5). Letting plants fully dry out prior to watering. TIP: Lift the pot to get a feel for the weight when light (dry) and heavy (wet).
