Hello Growers, Purchased the SP-150 for a 27x27x63 Mars-hydro tent. The tent holds three five-gallon pots with a little wiggle room for humidifier, but I opted for three 3-gallon aerated pots. This leaves plenty of room for fans, a DIY co2 generator and the humidifier. Legal in my state for medical card holders. Shortly after purchasing i received an email from the seller with tips for light distance during various stages and optimal temp/RH which was nice, but I’d assume anyone buying these items already knows this information, but I digress good information and appreciate the follow up. I rarely leave feedback on items unless I’m thrilled with the device. I paid full price and was not provided a discount of any type for my opinions. MarsHydro lights are top shelf quality and this light although smaller than my last unit has better par and pfid measurements. I probably could have gotten the sp250, but my concern was size in the tent and would it be touching the mylar. My plants are happier now than prior and I would recommend MarsHydro gear to anyone interested. Recently switched from an automated Grow device (grobo) which was less than advertised and really poor lighting. In a few weeks I’ll make a YouTube video of this setup. In the meantime I pulled a couple of pics and some footage from the IP camera inside the Mars tent. Items I purchased (from ecogrowhawaii.com) Mars Hydro SP-150 Mars hydro tent (27x27x63) 5 x 3gallon aerated bags A timer switch set for 18/6 (you can go 20/4 photo all the way to flower if you choose) Massive bag of FoxFarms super soil (opted for soil, but next grow I may flip back to DWC or rDWc 4 small adjustable 6in fans that clip onto the side bars Carbon filter with fan, switch w/ sensor and venting tube along with some ducting tape. Full lineup of advanced nutrients including advanced feeding (not just the basic) My only complaint which really isn’t a complaint more so feedback would be the lack of an entry point near the bottom half of the tent for fresh air input. The tent has Velcro with mesh, but no intake hole other than the one used for power cables. The top has an easy outage for getting the heat out ect The light itself is surprisingly cooler than expected. Upon unboxing I assumed the SP-150 would have put off a lot of heat, but truth be told the light merely raised the tents temps a few degrees. Having the fans setup on all four vertical poles at 1 foot intervals really helps push the air around and ultimately out of the tent. Even added a cheapo IP camera to monitor without opening (video uploaded). Two pots without plants had seeds added the day before and have already popped. The single plant with 5 nodes is only 2 weeks into grow, so it’s really taking advantage of the strong light and optimal grow space! All in all I’m happy so far with my purchase of about 2 weeks now. I fully recommend mars hydro products for all of your growing needs seed to smoke. I’m growing some top quality InHouse Genetics and some MephistoGentics. My next will be a few months from now, but 5th Element and some other InHouse seeds. Mars product grades Shipping - A+ Packaging - A+ Quality - A- Longevity - TBD Thank you MarsHydro -James L
