Super Stealth Grow

I got a thing for photography and so im experimenting a little. Day 8: lights dropped to 20cm. Should be around 400 average PAR. Day 9: roots coming out the bigger rockwool cube. Allowing them to air prune for maximum root surface area before hydro Day 10: All three are growing at the exact same rate. Day 11: Roots range from thick to thin. Thick for anchoring and thin for better absorption. We are air pruning thick roots to induce thinner side roots. 19/03/2020 Day 12: leaves were a little droopy due to saturated rockwool cubes after watering. Fixed by shaking the cubes to get rid of excess water. Day 13: Roots feel ready for hydro, transferred them to a little hydro reservoir and waiting to go into their final RDWC system. Day 14: Roots are let free and they are enjoying the oxygenated water End of week 2 report: The seedling stage is now over, really excited for them to take off. Had a little issue with water evaporating from the rockwool cubes and leaving the salts behind, raising the ppm of the water in the rockwool cubes. Had to wash the cube completely and covered them with a plastic cover.
