How many grows should I expect to get with the spider farmer 4000?
Loving it to date.

Hi spider farmer i have the sf4000 but its lost it brightness ppfd as half and the draw from the wall is 160w the dimmer is on full 100% all the lights are on could this be the drivers or dimmer its 2 years old thanks

Is there any discount coupons or codes for Rollitup members for buying on Amazon or ebay? Thanks.

At what heights would you run the SF4000? I’ve seen slight stress at 18 inches in flower had to dim down to 75-80% but a very awesome light. My forth grow and I’m truly amazed thanks Spider Farmer!

What's your shipping rates to bc canada want to buy another light from you in the future
