Indoor grow light diy

[Daan Posthumus]

Hi - I have a small space (shower cubicle) not used 1.2m x 1.2m. I will line the inside walls with reflective mylar. I'm on a tight budget so I'm currently researching my options regarding led lighting. As you know this is the most expensive part. It seems possible to construct a LED light source with these LED cobs fairly easily so I'm wondering how many of these cobs will I need per plant if I have 1 or 2 plants in a small space like that. The cobs are full spectrum LED 50w from https://m.lightinthebox.com/en/p/1pc-cob-new-design-creative-led-grow-bulb-cob-chip-aluminum-for-diy-plant-flower-seeding-light-50-w_p6747851.html?prm=1-2.2.1.1&from_cid=52653

Thank you

Rather wait until@growopz get new stock or just buy from other people on this forum. My personal opinion is a no no.

On that same site... this might be a better option.

Have absolutely no clue about lights.. but I think this one will do better..

Hi, Thanks for the tag, @SkunkPharm

Finishing up backlog on small lights and receiving the rest of our heatsink order from January, next week finally, so am expecting to have the grow bar range back up soon, and new high efficiency veg range after that.  

If in big rush for a small light,

Looking at the links above, the one website is just random chinese crap.  I would advise against that.   The modugrow one looks pretty sweet.  I can't tell what the difference is between their 90W lights, but the specs are solid.  It's 1/3 of a standard 240W Quantum board light, for R2k.  The QB-75 will be back next week, and is going to be R1250 going forward.  Compared to the 90W Modugrow, the QB-75 is about 10% less efficient, and 15W less, but also costs R800 less.  So it's a slightly different value proposition.

I got 2 Modugrow because I was impatient would of loved to get a QB from Growopz or Leon LED. But I am happy with my purchase and happy to support some local guys.

Hi Growopz - I will have 80 x 80 x 245  cm available to me so I,m thinking 1 plant and light stress or scrogging and good nutrients etc. Will the QB-75 be sufficient for this grow? My budget max is about R2 500.

[growopz]

@Daan PosthumusThe QB-130 & 120W Luminus CXM-32 will both be R2500, and more appropriate for 80x80. 

People use up to 240W in 80x80, so it's all relative to expectations. The tent size just sets a max on the amount of light you can put in there before you get diminishing returns.  The max is around 240W for 80x80.

So an experienced grower can yield 75g+ with the QB-75.    Yield correlates best to light wattage, with the QB board's efficiency important, but only accounting for max 18% difference in yield, at the same wattage.  (That's calculated from the efficiency difference between running LEDs at nominal efficiency (65mA per LED) vs max power (200mA per LED).  )

Hi all, before I start, I'm new to the forum and wanted to introduce myself, and very glad to be here among like minded people. 

I'm currently on my second grow and can vouch for @growopz products, not only that but his knowledge on the field and build quality are second to none, which is my personal opinion and experience with them.

Look forward to sharing in the adventure with you all, and growing with you all in every way.

Welcome and enjoy bud..

@Daan Posthumus, did you come right bud? 

[Daan Posthumus]

Hi Crex 

At this stage the cost of getting everything set up for an indoor growth is a bit much for someone with no knowledge whatsoever. I've decided to set up in my courtyard. There is adequate sun and airflow and privacy,  so I'll start outdoors until I know more about the plant.

Now to start researching what plant I should go for in a courtyard - I was thinking autoflower -- and since I'm in good health - something wonderfully abundant in THC.

We talk now.. or next summer? Yes you can put Autos.. sun strength would be enough, duration.. more is better. So if you can add them a light, would help. Summer.. autos work very well.

If you want something with a good kick, try the Gelato from 42FastBuds, would be my recommendation.

Get good soil.... IMPORTANT... Plant them straight into a 30L pot. Ensure the temp does not drop below 20ºc and give them as much sunlight as possible.. If you have good soil, no feeding required. Just do it.... and grow....
