Rangaku
started grow question 3y ago
Has anyone ever moved a plant from HID lights to LED during flower ? Keen to hear from your experience as it’s looking likely that I’ll need to do exactly that in the near future .

Yes it can be done. A lot of times you may need to add a little more cal mag is about only issue. Plus Temps won't be as strong. Good luck. 🌱🌱🌱

Is it too late for scrog and have I had the light too low during the veg stage?
So I noticed pistils appearing and now I'm worried that I've had my light too low during veg (~8k lux). Is it too late for scrog at this point or will they continue to grow? I've now bumped the light up to 22K lux should I lower the light to increase the intensity even more? TIA

Light Scedule to 24/0
I just installed a new light and now have a nice even 1000 PPFD across canopy. If I go to a 24/0 light schedule will she be ok? I started at 18/6 originally.

Mars Hydro TS 1000 [3500K,100W, LED light] (Plants @ 3
Questions: See photos. 1. MARS Hydro TS 1000 will not support 4 cannabis plants, correct? Support = Obtaining full plant potential. 2. The Chinese 3000K lighting won’t “hurt” my plants in veg, right? It’s just simply isn’t the lighting that works for veg growth, yea?

Too early to turn up the dimmible LED light on my seedling?
Unsure if it's too early to turn my light up just yet or wait till more leaves are growing. Currently at 25% (10,000 lux aprox.) using the dimmer for a 120w LED at 20 inches from seedling. Thanks in advance.

LED Light Spacing
So my taller plants are starting to get bright green on top. My light is 25” from the tops. I measured today, and if I keep the lights that far away during flowering, I hardly have any space to grow them taller. It’s a 6’8” tent. The bloom light also isn’t on yet. What do I do?

How much light does a seedling need?
Is there a limit to what it can use? Could an LED grow bulb a couple inches away provide enough light? Up to what age? Thank you so so much. My first grow and I really appreciate it! Specifically this one https://www.gelighting.com/led-bulbs/e2624/ge-grow-balanced-spectrum-br30#

Is it worth adding a LED 18w 2700k strip light for last few weeks of flower?
Should I add this light for the last few weeks of flower? I have a Streetlight 18w LED strip see pics. I was thinking that if I added this strip designed for flower to my tent like a side light it may help my Viparspectra V300 in fattening those buds a little. Thoughts?

light on humidifier :(
okay I think I might have fucked up (lol). I bought a new humidifier. And I didn’t realize it has a light in it. And i run it in the ten over the whole night. It’s not powerful at all but it’s also not just a little led. Do u recon my plant will be okay. I covered it now.
