Lighting

I’m looking to cover a 3x3 tent for 4 plants with lighting. I’ve been looking at the spider farmer sf1000 I was told I would need to run two of these. In order to get full coverage through veg and flower. Wanted to see if anyone has used these and if they are worth the money.

Grab a 350r from hlg and be done with it

I did a lot of research on lighting before going with Chinese brand LED's, one of them a Spider farmer. Everything about the lights I have bought is great. I have a par meter, and have tested specs, which are right as they say they are, and perform well against American "made" lights of the same parameters. There is a lot of hullabu back and forth about light brands, with some people bashing Chinese manufacturing as patently inferior. Many of the parts for the more expensive brands are build in China anyway and assembled here.

A 3x3 is just under a square meter of canopy.
I would look for a fixture that's capable of generating at least 750 umole ppf to achieve a ppfd over 750.
Spider farmer specs the sf1000 at 250umole ppf, so it would require 3 of those fixtures to achieve what I would call adequate lighting levels.

Okay thanks for that that. Decided to change it up tho going to go with a 36x20x63 tent to put inside a closet.

Currently in my 3x3 ive got a hlg100 (4000k) vegging my plants. Then I’m gonna use my 2 optic phat slim 1xl’s + the hlg100 for Flower (12/12). These 3 lights give me 303watts of high quality leds, so that should perform pretty well.
That's just under 1/2 sq meters, so I'd look for a fixture that can generate about 300 umole ppf.
What do you think about running 2 spiderfarmer sf1000?

I find that without using supplemental co2,750 ppfd is about the max most of the strains I've run can handle without signs of distress.
A pair of the sf1000's will produce about 500 umoles ppf and since you're spreading that out over about 1/2 sq meters it will produce a spot ppfd of 1000 across the canopy.
