Nice selection. You've got all aspects covered...relaxing Indica to uplifting Sativa
Yeah, 1000w might be too hot in your space without adding some cooling.
My strategy for controlling heat is first to skip summer. Then, I run the lights-on period overnight, both for cooler nighttime temps and cheaper nighttime electric rates. My reflector doesn't have the flanges for attaching ducting, so I just have my extraction duct up above it venting out a basement window. Seems to work out OK for the (9-month) cool season.
I've been running cheap Plantmax bulbs. The 400w MH is about $10 and the 1000W HPS is about $25. I recycle them after two grows. I've run Hortilux bulbs in the past and I can't tell any difference.
Your seedlings are looking good! I like it when they all stay about the same size.
The 600W HPS Ushio HiLUX GRO ... according to manufacturer...
...has an Optimized spectrum, distribution pattern, lumen output and irradiance, maximized output in both red and blue spectral range, for maximum flower yield, and added blue spectrum for vegetative growth efficiency...
...bla bla bla...
But it has good reviews, was ~60$ US, and I thought I'd give it a try.
I'll be using the MH only for the first half of VEG, then switch to the HPS @ 600W, so I wanted an HPS that had a more balanced spectrum (more blue). More blue is good to have "maybe" less stretch, mostly when switching to 12/12.
The spectral distribution graph seems to indeed be advantageous... compared to others I looked at.
Others not costing a fortune I mean.
