With a PPFD at 300 you well only get a DLI (Daily Light Integral) of 25,9 if you run your lamp 24/7.
From what i know seedlings/you plants need a DLI of about 20, so you should be good but i would aim for a DLI of at least 30 even for small plants.

Try the same PAR but with lights closer. The seedlings turn out stretchy when the lights are far away

Par is lights output, wavelengths and such area covered and so on
What you're needing to understand is ppf/ppfd.
4-450ppfd for a young veggin plant.
Have a read on growweedeasy to understand. Ill try find a link and dm

Bad idea?Will a mars hydro TS1000 be too strong for a 60x60x140cm tent?
I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.Other. General questions

Lighting cycle for VEG stage. Is 24x7 OK?Hi,
Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED
Thanks,
Mr.STMSetup. Lighting

Willing to spend around £500 maximum as I really want to invest however most videos on YouTube are marketing their own. Really appreciate your advice.

When did the flowering start?The LED panel, after switching (Ts600 Mars Hydro), stayed slightly on even during the dark hours. I managed to fix the issue, but I'm not sure how to count the flowering period. The plant had shown some differentiation, a few pistils, and a bit of stretching. What do you think?
