Lumatek attis 300W

RFarm21started grow question 5y ago

Good afternoon Farmers. I have a Lumatek Attis 300w LED and I'm using it at 100% (it includes a dimmer that can be adjusted in 20% increments). I wanted to know if there’s any problem using it at 100% from the initial phase or if there are specific values for each phase. Thank you very much!

No problem at all bro, yeah 80cm-100cm sould be perfect for you at 100%. 80cm will be at the top end at around 300ppfd so that's why I think you'll possibly be able to go higher. Decent space you've got available for them at well. Good luck with your grow mate!

Thank you so much InspireMe, tireless! When I get home, I'll take a good look at that link! I can't lower them too much because I have 4 in a tent that's 2 meters high, 1.20 in length and width. Right now they are about 100cm away, and my initial idea was to adjust them in the same way as they grow. Thanks again for your availability!

I'd say that will cover you for the time being, you'll be able to tell if and when they want more as they will start to grow towards the light faster. Your best off reading the plants to figure out when to adjust it. Feel fee to drop me a message if you need help in the future or if your unsure of anything, if I know the answer I'll help you out. Hope this helps mate 🙂

So for the seedling stage if you want the light on 100% you will need the LED at about 80cm. I'd probably dim it to 40% and have it at 40cm to save on electricity. Unless you need the coverage. Then have it higher.

Brown spots What is this? It's affecting newer growth, first or second set of fan leaves off thee top of the colas. Also, this drooping, is this stress from the light? This is the center of my tent, and would appear to only affect tallest colas of this plant.

3000 watt power use This is my first time using such a powerful light in my opinion, 3000 watts seems overkill but that's what i want. The question IS, is it better to have 1-2 plants under the 3000 watt or worth it to manage 4 at a higher distance? Cheers. Don't keep techniques in mind.

WHAT IS CAUSING MY LEAVES TO CURL? (Day 64 pictures)The leaves at the top of the plant seem to be curling up. My first guess is that there is too much light. I recently moved my light down to 12 inches above the canopy. The PPFD should still be under 1,000, but I don't know what else could be causing it. Please help. 🙏

Secondary Lighting Would there be any sort of reason I shouldn't add a second less powerful light to the side of my tent? My thought is if my goal is getting more light to the lower growth wouldn't that be a good course of action?

Light distance and power with a 205W Sanlight LED Sanlight told me I should use it dimmed at 80% and 45cm when in flowering. I was aiming to reach lower buds so I put it at 100% and 50cm from the upper buds. The tips of the leaves are slightly burned but no bud bleaching yet like my last run (at 100% 45cm). What's best ? Thx !

Temperature VS More Light which is better for buds size and potency Should I continue to use two LEDS if temps are reaching 87f during flower (day 1) or just move plants more towards center of tent and use one LED for better temperatures (75f) (only growing two plants). lights are 1000w bestiva and are in a tent that is 24"x48"60".
