Hypothesis: Adding a 1" layer of soil to the bottom of the container on the first day of flower will give roots space to grow for flower cycle
Test: We took 3 plants that had all been in veg and had filled up there containers. Removed plant from container and added 1" of fresh coco to the bottom of the container. We then put the plants root ball back in the container on top of the Fresh Coco
Data: 3 plants were selected out of 13 to have the extra coco added so we have 10 controls. We will compare Yield numbers and some visual observations.
Enviroment:
Tent: 4x4
Tray: High Tide 3x3
Container: 32Oz Foam cup, cut at the bottom
Medium: Coco flock
Light: True Northern Lighting 200w fixture
Nutrients: Cyco Platnium series Bloom a+b, swell, silica
Method: Flood and Drain 4 times per day for 10 min 3 hour intervals
Reservoir: 50 Gal O2 added 2 ml/Gal 2 times per week, Topped up with water and nutrients, Never changed for entire flower cycle.
Strains: 2x Pineapple Express, 1 x Blueberry Kush
Picture 1 : Roots growing out top of coco, we did have a layer of hydroton ontop, it was removed for the picture.
Picture 2 : Label on Foam Cup
Picture 3 : Root Ball out of cup, Very full for lower 75% looks to have taken over the added coco
Picture 4 : Root Ball Cut in Half, Was dense with root fibers hard to cut
Picture 5 : Root Ball washed off with warm water to show root structure better
Picture 6 : Root ball Close up, You can see where the old bottom build up of root mass was by the thick root line about 1" up from bottom,
Another observation is that the soil above the rock-wool cube is moist but not the same dark color as in the rest of the root mass.
We only flooded these trays about 1" up the foam cup and let the hydrostatic pressure pull the water the rest of the way up to the
roots.
Conclusion: The plants fully used the extra coco in the bottom to expand root structure through the flowering cycle. During the stretch phase plants still grow new roots as they lengthen there stocks and widen there fan leaves.
Did it help to increase quality or final yield of dried flowers? We will answer this question when the data is available.
Also Look forward to our full 200W Grow Journal that this small experiment was carried out in.
