600-750W E&F Indoor Grow: Neville's Haze, The White, Romulan x Grapefruit

Howdy all.
Currently growing five Neville's Haze seedlings and 2 clones: Romulan x Grapefruit (which I'll call 'Starfruit') and 'The White', both produced by 'Dark Heart Nurseries'. I plan on selecting one NH mother plant, and another from either clone.

Eventually I will be constantly rooting 32 clones in an aeroponic box, vegging 18 plants in net pots on a 3x3' E&F tray under a 600W MH lamp. Drip irrigation will be used to reduce flood cycle frequency. Blooming on 2x4' tray under 750W HPS lamp.

I'm excited to see

Clones: Day 4 since purchase
Seedlings: Day 5 since germination

Neville's Haze seeds from Mr. Nice Seeds - Estimated Harvest Date: June 22nd (~24 weeks)
5/5 seeds germinated. Not yet rooted in cube,

• 7' below 600W MH lamp.
• Planted in rootcubes soaked w/ enzyme and 5.5 pH water. Contained in 2" net pots.
• Contained in 'humididome': H=80-95% @76F. Tray kept wet for ambient humidity.

At day three, first two sprouted seedlings became limp and stressed. Likely over-watered rootcubes. Staked stretchy plants. Applying water to tray sparsely.
