Thanks friend! Hmmm… Mars Hydro. Kinda mixed feelings. I have a TS1000 or TS600, forget which one it is… but that one is way more cheaply built than the SP250 that I have. The TS600 has a no-name cheap driver and I don’t really like the way the plug connecter is mounted on the board. Also I don’t like the dimmer setup (you have to have a screwdriver to move a pot directly in the driver), but they’ve changed that since I bought it. The SP250 has a meanwell driver, so that gives me a little more confidence. But to be honest, I find that my plants seem happier under my Timber Redwood 3500k Vero COB LEDs. I’m not sure it’s a spectrum thing, or what? I did pull almost a P from the SP250 from the last run with mono-cropping SSDD, so it will grow some herb. But I just brought down another clone of that same SSDD plant that was flowered under the Timber, and the buds were WAY bigger, twice the size in most cases, and less larf. Sooo yeah, I’d say there are better products out there than the Mars Hydro, especially given their reputation of not supporting their products and their ridiculous photoshopped ads. If you have any electrical and DIY skills, then definitely build your own LEDs, if not, then go with a reputable USA based company, Timber, Fluence, Gavita, etc.
I bought it, really liked the design. I really placed an order just for the shirt, but decided to grab some beans while I was at it. Can’t rep the co without growin’ the beans 
Excited to see 'em! I really like checking out other people’s reports of the same genetics so I doubt it’ll be redundant at all Plus, very cool to see how the differences in everyone’s environment will affect the outcome.
Probably gonna grab the F5’s when Useful releases them, I’ll give you a heads up if ya want.
