How Many Plants Can I veg with sf1000 100 watt

I am aware that the light is only good for one full plant but was wondering if I could grow 3 plants and when 2 of them are ready to move outside do so. Ultimately only growing one plant inside after the other two have matured enough to be outside. I read that each plant needs 25/40 watts of lighting but is this the same for seedlings up until the point they will be moved outside? Thank you.

For 3 seedlings (or even more) the 100w will work, small plants will veg fine, so yes your plan should work. The 100w is good for about 3sq ft. for a single plant

100w will stretch to 2x2ft in flower.
It's weak but you'd still get reasonable results.

That's 25w per square foot.

In veg you could cover 3x3.
It wouldn't be ideal light spread, just because it's a single panel.

I've vegged under my 600w leds at 25% over 4x4 and it still gives good results, but they are bar lights and have a great spread.

If you only plan to do seedlings you can do 3 or 4 plants no problem.yoz just cant finish them they would strech luke crazy and stay thin

Yes, no problems with 100 watts.
I use ~ 60 watts. 3 x 2ft F strips. ~ 300 ppfd but then it's twice the size of the sf 1000 footprint.
I've 3 biggish plants in 10l pots,1 medium sized plant in 7l pot and 3 small pots with plants plus a couple of clones.
It's amazing how little light is required for vegging.

yea but it gets slow.more light more speed

Possibly, but in many cases more light more stress and less speed.

If I compared it to hps or mh the growth (when environment is perfect and plants happy)
Is far better under LED , even at 9w a square foot.
well there is a saturation point
At levels below 100 μmol/m²/s, seedlings may not receive enough light, leading to slow growth and weak development.
On the other hand, exceeding 300 μmol/m²/s can cause light stress, which might stunt growth or even damage the delicate seedlings.

As plants grow and require more energy for leaf and stem development, a higher PPFD range of 300-600 μmol/m²/s is suitable. This ensures robust growth and prepares plants for the flowering phase.

Ranging from 600-900 μmol/m²/s and potentially up to 1000 μmol/m²/s under ideal conditions (with adequate nutrients, CO2, temperature, and humidity).
For beginners, aiming for 800 μmol/m²/s is a good starting point.
