a good lamp ?
Hou_Stonestarted grow question 2 years ago
Good morning,
Currently I have an hps and I'm looking to invest in a good lamp. Do you have a good one to recommend?
I have a room 100x100x200 cm
Currently I want to take the mars hydro fc3000 I am not sure if it is powerful enough for my room? I would like to have opinions

100 x 100 = 1m^2.
300 * 2.8 = 840 umol/s in 1m^2 is 840 PPFD -- this will be good even for growing photoperiods on a 12/12 bloom schedule. You are good to go. You'll need proportionally less light for autoflowers / vegetative phase 18/6 cycle -- or use fewer hours, more height... 3 ways to skin that cat.
That'll be a perfectly sized light for a 100x 100 tent. high efficacy, great price, great build quality... i don't say that about all mars lights. i am not a fan-boy. They built it right. from diode count to heatsink.

that lamp will last longer tan most.. the diode count assures you of that... they power them at the same watts as teh samsung.com spec sheet testing paramaters.
put a little breeze on them to ensure longevity, but even without should be 7 years or more depending on yearly use.. .50,000 hours for an FC model isn't outlandish. The lights that run hotter with same diodes might reach 25-30k before tehy dim to 90%. (longevity curve on samsung.com spec sheet for lm301b / h will verify what i say)
The only reason you'd need more is if you tightly control environment and boost co2 to 1200-1300ppm ... then, you could probably use 20-25% more.

si la mars copre bene quel tipo di box e dovrebbe essere valida..
io personalmente mi trovo molto bene con Migro ha qualche watt in meno ma è ottima almeno per me
la uso in un box un po' piu piccolo ma copre 100x100 senza problemi

Mars Hyrdo TS600 - 100w but mistook for 600wI've recently found out that the led light I have which is a Mars Hydro TS600 is not in fact 600w and is actually 100w.
Do I need to compensate in any way? My plants look healthy but short, I don't want to put the light too far away that it's ineffective, how close is too close?a year ago

'Claws' on tips just after flowering started. Previous answers help - it is a bit worse. I keep a perfect VPD. What should I do? Flower wouldnt fI'm confused. For the first 3w I used LED as instructed 30-40cm, I had ~43cm,100%dim, everything was fine. When the bloom started yellow claws appeared and still there, maybe a bit worse, with 53cm and 75%dim. Mostly on BPP, one more plant showed her claws today aswell. 😓

What lights for a 2'x3'x6' tent?What light or lights for a 2x3 footprint? Veg and flower. Deciding between 2x Viparspectra XS 1500, 2x HLG RSpec 100, or a combo 1 of each. Budget is 200-300ish. Cheaper is better. Open to suggestions. Not sure if I should have 2 of the same lights or mix n match.

Can a 1000w LED grow light be closer than 60cm (24") to a seedling?Different sources are saying: 1000w LED light should not be closer to a seedling than 60-75cm (24"-30"). The seedling should be getting 5000-7000 lux, 100-300 PAR (PPFD 18h) and 12-20 DLI.
Question: Can I put the light closer at ~40cm, dimmed to match the needed lux, par and dli

Slight leaf tip "burn"What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 1000a year ago

Auto seedlings, lighting question!Hi! I have a question. I am just about to start my first indoor grow, it’s relatively small, only two plants, both autos. I am using the Telos 6 mesh LED for lighting but I am unclear as to when to switch the power from 25-50%? Is it when the first true leaves appear? ThanksSetup. Lighting

Is this a sign of too much light?I’m noticing the leaves grow extremely close to each other, should I be concerned at this stage, should I pull the light higher back? This is day 3 of week 2, I’m feeding it full advanced nutrients line up for veg. And drying out for a day and a half between waterings

Viparspectra P2000 height and intensityFor those that have experience with the light I'm using, Viparspectra P2000, how high and what intensity percentage should I have it? Currently I'm at 21" at 75% power. Also, I run it 24/7. I have an app on my phone and it says my DLI is at like 56 which seems way too high.Week 3

Nutrient burn, Light burn, or Phos Def? red stems purple bruises,Noticed red lines leaking red into the leaves with purple bruising, and the starter bottom leaves seem to be turning yellow, with the leaves above looking dark green with spots. Is this signs of light burn or nutrient toxicity? And is it lacking phosphorus or just the strain gen?
