Can you help an old head be more up to date? Are my plans achievable?

Hey there,

Been so long since I've been in the world of growing, I have had some growing medical issues that I want to tread with weed so need to grow.
Back when I was interested in it the only thing you could grow with was vegging CFL and flowering HPS/metal halides that were super hot.

I've seen that LED's are feasible now, is this right?
I have a space that is 75cm deep, and 1m to 1.3m wide, and 1.8ish m high that I can grow in discretely.
Is this enough space, and will LED's work (I was hoping they will as i could do without the huge wattage/heat). My plan was to build a grow box out of mdf, line it, and put the filter and fan inside it. I was also hoping to grow 2 strains, (one high cbd if possible, and a high thc one, to hit all medical angles).
I've been advised autoflowering in this situation would be best.

Any ideas and help would be great, it has been so long since I've even looked at anything like this, but pain is messing me at the moment and I need something to help

Added: one other aspect here is it would be in a bathroom, would this be ok humidity wise?
lol welcome to riu, great first impression ey!!

Truth is both LED and HPS work, what works best for you will come down to environment.
If you live in a cool climate then LED may not be the best option. Having a warmer air temp is key and in a cool climate that means adding heat which kind of defeats the point of having a more efficient light source.

HPS is simple and has long served the growing community, a hot climate makes it harder to manage.
But unless your ambient air temp is already higher that desired air temp then it is manageable.

Which ever you go with you have to make sure you have the basics in place, which is a place to extract air outside the grow area , to remove the heat and so the air is replaced keeping co2 levels up.
This means getting the air outside ideally so it doesn't just recirculate back into the grow space.


Just stay away from cheap LEDs , work out which method suits your space and environment

Without knowing your full details I would be looking at 320w of white LED for flowering, half that for veg
or 2x 250w of HPS for flower with half that in metal halide or t5 for veg. You would want multiple smaller lights rather than one bigger one due to the shape of your space.
Or you could get a 315cmh and light 75x90cm and work with that .

I do not feel like rehashing another LED vs HPS argument. I have tried both types of lighting to a great extent and have various logs of some of it. simplicity is the main deal. You want equipment that is tried and tested (led is not they are still trying to find a proper spectrum) and is reliable.

you do not get equivalent yields using 60% of the power. Please stop spreading misinformation. I would love to see a log of your own where you tested 60% of HPS power with led and the results with strain info etc.

You’re entitled to your own opinion but please save the “if you get a proper” led bullshit for someone else. Because I have been there and done that and all you just did in that post I quoted was regurgitate the typical LED fanboy misinformation.

please feel feel to link me to a grow of your own where you back up the statements you just made with cannabis or any plant.
Go check out the lettuce thread in the LED section and find me (1) post of lettuce grown under LED that kills what others have done with cfl and T5 and does it at 60% power, please I would love to see that :D
If you pony up and buy a real big boy light you will crush HID yields.

Problem is it sounds like you keep buying knock offs and made a conclusion.

Op sorry for the hijack.

Two things you should always do in life and especially when asking for advice on this forum:

1) consider who is giving you said info: do they have experience with both sides of the argument,

2) is their opinion first hand knowledge or just something they saw on the internet?

I will leave your thread be there is enough garbage about led lighting already on this forum if you need anymore help and think I can offer any advice feel free to message me.

good luck
You're so dismissive of anyone who argues your stance. Learn to be more open to new information.

Resistence to change is the hallmark of a small mind..

That being said over grown for years under 600w HID. This grow I've upgraded to a 620w quantum board diy from hlg.

I'm in week 6 of flower and my buds are already bigger then anything I ever grew with my HID.

Like no kidding, 3 weeks of flower left and the buds are already bigger then a fully flowered HID bud.

Maybe you should learn more about led and stop using cheap knockoffs for your comparisons.

You guys are accusing me of being dismissive and little do you know I tested one of the first QB Proto types. Lol.

Welcome to RIU!

That is enough space.
Here's the link to the micro grow section on RIU:

As for the light, plenty of info above if you can wade through the rest; but suffice to say that both will get you where you want to go - but due diligence on your end will determine your results.

The above posts are much more educated on the subject than I am; but I still have 2 drying and 2 almost there in a modified box with a 300w blurple light that has a few blinky diodes. Hardly an optimum setup, but it worked; and will live on as a starter / veg space now that I picked up more gear for my current grow.

gl on your efforts, look around the site - I've learned A LOT from grow journals. Keep us posted!

When you're using technology that is new, it is developed at a rapid pace and often times gear becomes outdated rather quick.

Claiming you tested a qb proto type isnt really enforcing your stance.

Are you suggesting you are comparing proven HID tech against led prototypes to draw your comparisons?

You were one of the early adopters with lesser quality LEDS and a lack of knowledge on how to run them. Your knowledge is antiquated and outdated, quit being a fossil.
im sorry did the LED crowd figure out their incomplete spectrum yet? Lol

The companies are bleeding you of your money one nanometer at a time

See, you're so blinded by your need to push some anti led agenda. I'm not bashing hid but I've grown with both and leds have given better results.

As stated earlier..

I've grown for years with 600w mh/hps. I switched to a 620w hlg diy QB. The results are night and day. My hlg is producing better quality and quantity.

Im happy for you. And I’m not pushing any agenda. But building fixtures that do nothing but throw more of an incorrect spectrum at lights is not the answer.

Well I don't think anyone in the world knows the right spectrum, but quantity over quality worked for decades with hps and it still does with LED.


You obviously didn't have great results or experiences with LED but surely for all the time you've been on here you've seen plenty of people who had the opposite experience ?


Any how its still nice to see your back in the hood. :bigjoint:

you can grow with LED I never said you couldn’t but the plants don’t come out the same. And “most” people growing with LED’s don’t know what a properly grown plant looks like.

Good to see you around as well.

A properly grown plant is one that lives outdoors. You can get them looking right with led, you just need to have the knowledge to do it.

i grew with HID in 07-08. I had two 600w HPS in a 4x6. the buds were dank. when i got back into growing about 10 years later it seemed like LED was the only option. like my earlier post in this thread, it seems like HPS (especially single ended home grower setups) are going the way of the incandescent. ive been growing now for about 4 years with my LEDs and frequenting this site and the buds i grow now are a lot denser and danker than the buds i grew with HPS but of course that could just be the experience (or more likely genetics). so this thread has got me thinking, maybe i should try HPS again now that i have one of my strains completely dialed in. so i started shopping around and i quickly realized something. I only run 480 watts of LED in my tent. Then i gotta decide if im gonna run a 400w or a 600w HPS in my 4x4. Then i realized another thing, I've been getting over 1gpw of hard grade a flower with 480w of LED in a 4x4. You dont have to grow weed for decades to know what grade A flowers are, smoking for decades will do. So my question is this, and its a serious question because i have such limited experience with HID. Could anyone (with a straight face) tell me im gonna get over 1gpw of hard grade a flower with a 400w hps in a 4x4? Usual recommendation with HID is 50wsqft which is what i used to run. Don't think I'd have much success with half that. Even a 600 in a 4x4 still isnt 50wsqft and its not uncommon to see people recommend 1000w. So now were talking about adding 120-420 watts of power consumption to my tent that i'll also have to cool with more power consumption. No problem really as long as the results are worth it. But will they be? I really will try this for myself someday soon (despite these HPS systems becoming harder to find). I think this argument, like many others on rollitup, is one we can really only solve for ourselves.... Except the ideal spectrum argument though everyone knows thats 4000k 100 cri duh...

I'm really enjoying the light debate - but maybe this part of the convo should move itself to the "eternal light debate" thread.

Here's what I see the OP asking.

So far I can answer Yes, except humidity in a bathroom.

I'm a complete noob - my "Yes" is not to be trusted. Could someone with experience address the OP's questions?
