Motaybongsstarted grow question 3 years ago

What would be the different range of lux needed for each week? Atm running lights in 60% and with distance the lux is around 18000. Since is my first time using led any recommendations? Someone already with experience with sanlight? And its dimmer system? Thank you so much

Not familiar with that specific light.. I recommend this app called Photone if you have to spend.. it’s a quite accurate PAR tool that gives you a direct readout in PPFD. I try to be around 300-500 PPFD in first weeks of veg, 500- 750 after 2-3 weeks, then 800-1000 in flower (1100+ Only increases growth if you are running CO2 as well) I believe 18000 lux is good for your stage. I think that’s around 400-500 umols/s/m2 which is what I was calling PPFD up there 👆 . Definitely crank it to full when flower approaches

Sorry it was supposed to say “if you have to spend” like L.E.G. said - it’s a free download but a ish purchase for the in app light meter specific to your light. I’m in no way affiliated with or compensated for suggesting this app but it really has changed the game for me as far as adjusting lights hang height and distance between multiple lights. But if you have something that measures lux properly you can do the math yourself on it.

...and yes, Photone is a great way to go. Free to DL but the profile for the type of light will cost 6.99$. That will net you actual Lux, PPFD and DLI readings.

Rather than thinking in lux you should be looking at PPFD...and how that translates into DLI. DLI is the amount of useable light exposure in a given day. So it's the strength of your light in relation to the length of time you're giving your plants light. A bit of quick online research on cannabis PPDF and DLI will net you what you want to do.

How many plants in a 70x70x160cm tent with 100W?Hello, I have a grow tent kit 2x2 with a 100W 301H EVO Spider Farmer light. I have put there three 11L pots. But now I realize the size/light of my tent might not be enough. Could I manage by adding an additional 60W lamp you reckon or is it best to discard at least 1 plant? Thx

Do you lower light intensity and temps towards the end of flower?So I’m in mid flower, start of week 7 to be exact. I’m curious on when you guys start pulling back light intensity and going with a little cooler temps. I’m running a 240W S33 from AC infinity in a 3x3. Should I be going strictly off of PAR or VPD at this point.
