Light cycle question
Disorder2started grow question 5 months ago
Hi guys,. My auto are 2 weeks veg today. I started LST yesterday and they’ve all responded well and redirected to light. My question is, is it too late to introduce a 18/6 light cycle? Currently 24hr.. thanks

Never too late............18/6 is optimal........all cannabis plants NEED sleep.

No it's not too late .... Go ahead and switch it they'll be fine , I actually run 18/6 on my autos at all times.

It's never too late with an auto....they really don't care much about the light cycles. The idea that 24 hour light is somehow harmful is ridiculous though. Ruderalis genetics evolved to handle the light cycles in the arctic circle. Go try to find some darkness there in July lololol. Now if you wanna manage heat or use less electricity, it's understandable.

Light Intensity/Distance for Germination and BeyondI have a Bloomspect SL600 (85W) for one autoflower plant. I am looking for advice on light intensity/distance for germination and beyond. Currently, I have the light at 50% intensity at 14 inches going 20/4. 14 inches is the highest I can go due to space limitations. Any advice?

When your Led is too powerful for your surface. Should I raise the Led's distance to plant and its intensity ?In your experience, would it be better to put my (too) powerful LED at 60% 55 cm from the plants or 80% at 70 cm ? I have 1.511µmol/m²/s at 80% (which is A LOT apparently) and 755µmol/m²/s at 40%

DLI/PPFD for autoflower seedlings on a 24hr light cycleWondering about DLI/PPFD for autoflower seedlings on a 24hr light cycle. Running the lights 24/7 to keep temps up in my tent, with PPFD at about 280. This gives a DLI of 24. Too much light for 1 week old seedlings? Should I move the light a bit further away?Week 1

Light Distance - Question for allI have a question for the collective here. Lots of questions about the distance to lights. My plant tops are about 12in. Away from my 250W LED light, the plant seems to be doing fine, no issues. What is the closest you have had you plant to lights and not seen an issue?

Led Light dilemmaI'm not sure if I should use my led light on full power? I know in the vegetative phase she needs 300-700 PPFD and I have a PPFD meter (app). On full power, I place the light around 45-50 cm from her to get around 500 PPFD but I don't trust the app , so what do you think guys?Week 2

DLI and LightcycleIch habe einen Knoten im Gehirn. Eine gute Idee bei Autoflowers ist es, den DLI bei ca. 40 zu halten. Wie macht ihr das genau bei einem Lichtzyklus von 18/6 von Start bis Finish? Lasst ihr eure Lampen wirklich nur bei ca. 600ppfd laufen, um nicht über DLI 40 zu kommen?Setup. Lighting

Optimal Light DistanceMy plants are experiencing some heat stress and my light is currently at 28 inches distance and thinking to lower it but it could hurt more the plants since I just did some LST and topping. Is it okay to lower it down to like 25 inches? What is the best height distance? TY! :)Week 4
