Im using a 4x4x8 grow tent. I had trouble with my 1st grow. Going to start 2nd but i feel im in definite of a new grow light. 1st: which light would you recommend for that size tent? 2nd: Do i need to have the blue and red lights during the grow? 3rd: I am looking for a light that gives off good PAR and PPFL.
I love this light, and so do my plants! They exploded when I replaced my burple lights with this! I am in a 4×4 tent.
ALL PICS ARE 100% SPIDER FARMER SF4000-2000
I just received the newer sf4000. I really didn’t need it so I searched for discount codes and right at the last min I entered WELCOME that brought price down to $260 (SF2000) so I own my 3rd sf4000 and 2 sf2000. I also was a hps guy using eye hortilux 120$ bulbs. In the end I’m really happy, I downsized my custm built 24×32 grow barn down to a 11×8 and 6x6veg cause Michigan just exploded with herbs. But yeah if you don’t need 5 foot penatration then these twerk great lol.
Got some new cuts from getseedsrighthere and excited to see if white truffle, winter sunset, empress2,,Glitter Glue, rs11, blue cookies, violet fog, are as good as my own strains. I like breeding and searching for that gold mine.
my first full spectrum grow. this rig is way more than i expected, and that is a good start. good construction, waterproof, dimmable, kick*ss spectrum. IR, too. shipped to my home within 4 days. good packaging, and it was discreet. WAY TO GO SPIDER FARMER!
Wonderful light, extremely worth the money. Works great, people think I’m showing them pictures out of a magazine when I show them my plants at the end of flowering. I have a decade or more experience, and this light is noticeably better in every way than other expensive setups. Cheaper to run, better results. Get this light!!
