Those Mars Hydro SP250 look interesting too.
I wonder how it would perform against the invisible sun 265 XL. Or would it definitely no questions asked be worth the extra £100 for the Invisible Sun.
Height is something I wasnt too concerend about but yeah thinking about it a 180 height tent would probably be better than a 150 height tent I was just trying to conserve some heat with out needing to consume extra power from heating. But I was going to scrog with small 5l pots so height might not be so much of an issue tbh.
Not sure whether to just get a ts1000 for vegging in my 60x60 space and buying an sp250 for a 120x60 flowering tent.
Or spending a little extra and going for an ISH 265 XL type R and using the small ISH 120 60w board for vegging with a home made frame and driver etc.
I can find loads of light intensity tests and reviews on the Mars SP250s but not so many on the Invisible sun units to compare.
I mean if watts are watts then the 245w mars should do much better than the 100w sun. They also state similar umols/J
Ive done 2.6gpw with my ish320 3000k . Quite impressive tbh . The frost levels are out of this world . HPS cant even touch em . This 320w led lamp is worth a 600w hands down . Only thing is theres less light spread unless you make a reflector witch i will.make eventually
