Noob with question about lighting

[Alfonso85]

Hi fam! i would appreciate you advice regarding lighting, i started an indoor grow with what i had a hand at the moment, im growing 3 banana purple punch plants in coco coir, each plant in a 5 gallon capacity pot, but i didnt have access to proper Grow Lights and i found a HOFTRONIC LED High bay Saturn 90W 120° IP65 dimmable 5700K 190lm. I know it wont be as effective as a proper grow light, but do you guys think i might get a good yield out of this? Im using a 180 CM X60CM x60CM Grow tent. Thanks for the tips!

That might not even be enough light for 1 plant much less 3 plants. You need or want about 100w to 150w per plant. Otherwise this could happen to you. When I tried growing 4 plants under a 100w LED ..... But this was back in the days when companies would claim it was equal to a 600w HPS bulb. We know better now.

The 95w LED you have is only going to be good enough for 1 plant. Any more and you'll get stretching and lanky think branches and small buds during flowering.

I agree with No3odiesShad0w, that might not be enough light for one plant, but also, I have concerns concerning the color of the lights, not enough 'red' frequency for the flowering mode of the plant, fine for the growth mode though. Some of the better yielding LED land have an average light of around 3700 Deg. K, which has more diodes in the 720nm (red) range. The plants seem to produce more and large buds when given more light in the red range during flowering. Alfonso85,
you would most likely benefit by adding some 2700 Deg. K CFLs for a last minute 'fix' during the flowering stage. Just my $0.02 worth.
Good luck with your grow!

Good catch DW2 I honestly didn't even think about the red/blue light balance on the LED itself. I'm not familiar with the light fixture myself but I know for a fact not all lights are created equal.

Thank you for the answer, i will try to get a proper growlight, i dont want to waste these good seeds.

Unfortunately Number 3 is correct.

I have some highbays here, similar specs to yours but 150 watt. Probably big enough for one auto.

A 2 x 2 grow tent I'd go with https://www.spider-farmer.com/produc...ed-grow-light/

It gets good reviews and is on sale for under $100 atm

If you want a good 2 x 2 cheap I have a hookup that gets them cheap and they are good quality. Not name brand but I've run all the brand tents in the past and this one is comparable in terms of quality. I added the hygrometers myself.

Private message me and we can arrange.



As far as lights, as has been mentioned, 100w won't be enough light energy for all the plants you have. A good rule of thumb when picking grow lights is to do it by sq/ft of grow space. For example, in a 2 x 2 you have 4 sq/ft of space. You want between 35 and 55 watts per sq/ft. In a 2 x 2 that would mean 35w x 4 sq ft = 120w. This would be the minimum amount of watts you want in that tent. 55w x 4 = 220w. This would be the maximum amount of light you want in a 2 x 2.

You didn't mention if your plants were from photo or auto seeds. Personally, I wouldn't grow to flower more than one plant in a 2 x 2.

I have had good results with the Spider Farmer SF series.

They are available on Amazon

I'm growing with the SF2000 and I have zero complaints
