Day 4
3 A-train and 1 Apollo 13 seeds soaked in RO water for 24 hours. Soaked the rockwool cubes in 5.5 ph RO water for 24 hours. Rockwool cubs were rung out and all 4 seeds planted.
The goal is to establish the best genetics between the 3 A-train seeds to establish a mother plant. So far only 1 A-train seeds has sprouted. pulled away rockwool covering to examine 2 non sprouting seeds. unable to determine what the issue is.

3x3x3 tent with ventilation, heating mat and dome. Dome temperatures exceeded 90 degrees at one point. hopefully this did not ruin to 2 non sprouted seeds. temperatures inside the dome stay between 75-80 degrees and 60-80%humidity. will be getting a more accurate and reliable thermometer soon.

Day 7
ran into issues with the rockwool. @ seeds never sprouted. 1 seed had obvious mold covering it, the other tap root came out, no signs of mold however the plant still has not sprouted.

From Day 5-6 the light was left on or 24 hours by mistake. After a short period of darkness and turning the light back on the A-train seedling was suffering. The root base appeared unhealthy, and the rockwool cube appeared dry. the plants stem could no longer support itself and collapsed. in an attempt to save the plant i removed it from the rockwool and transplanted it into my home made cloner. roughly 1mL Micro , grow, and bloom from general hydroponics and 5 mL Hydrogaurd. A-train seedling was not looking well future uncertain. Apollo 13 seedling looking very strong.

Tent temperature hovering around 78-80F humidity is low. need to install humidifier.

In doing some reading for future seed germination techniques for hydroponic growing i have decided to abandon the rockwool method and adopt the method outlined below.
1. place seeds in aplastic bag with damp paper towel at temps 65-80F. after -2 days tap roots should appear
2. after 3-5 days tap roots should be long enough to place into foam collar and place into cloner aprox 1-2 inches

Future diary entries to be formatted differently.

Day 21
PPM 150
Ph 6.1

PPM & Ph remained consistent over the weekend. water level dropped slightly. all plants now have roots that reach the water level.

2 seedlings look very healthy, the other with the discoloration is improving. Yellow spotting has not spread any further.

Plants are at nodes 3 , 3, 4. Hoping to be able to top the first plant come next weekend.
