The lights

[Za Weed Lover]

PHello Canna Fam. 

Here looking for advice, 1st time indoor grower. Have experience with outdoors.

I want to set up a grow room that is 2m by 2m. With about 6 to 8 plants in there or can I put more.  Not too small. 

The question is , how much do I need? Looking at buying HPS 600W. Would one cover for all stages of growing? 

Also I want to feed organically? What experience has those who have tried it, gotten? 

How does one generate CO2 ,cheaply?

It will be a struggle with that light to grow in such a big area. You could get away with that light in a 1.2x1.5m area. You could still grow your 8 plants just grow them smaller. What type of CO2 do you want to supplement with? Propane burner, tank with regulator or just a simple chemical reaction. CO2 needs a sealed grow room. Are you mixing your own organic soil or are you buying a premix? The are lots of organic nutes availible. Biobizz is probably the most well known and easiest to use.

Thanks for the heads up . Haven't build it yet and could make it smaller.  So you saying one  would work? It being smaller, would that affect yields. What would it be like? Don't need to make it that big but want as much light as I can get .

Also I want to grow as organically as possible. Can it be done through compost tea and sprout tea? 

Looking for the cheapest way. So a chemical reaction? 

Would get premix   .

[SkunkPharm]

I would recommend a good microbes mix inoculation 2-4times during your grow and then just feed the microbes. Compost and sprouted seed teas with some molasses. Silica and amino acids.

All plants are different but can be placed into categories based on light needs per day. This is known as Daily Light Integral (DLI). DLI is the amount of PAR received each day as a function of light intensity and duration. This is known as moles per square meter per day (µmol/m2/d). A direct correlation between how much PAR your plants are exposed to and for how long each day. Generally, the vegetative stage of plant growth requires 16 – 24 hours of light per day, while the flowering stage requires up to 12 hours of light per day. Below is a general breakdown of how much PPFD is needed for plants to thrive during the different stages of growth.

Sustainable Veg   | Production Veg   | Flowering Plant
50 – 200 µmol/m2/s  |  150 – 400 µmol/m2/s  |  400 – 1 000 µmol/m2/s

These numbers vary based on type of plant and environmental variables like the introduction of carbon dioxide into the environment. 500 – 1000 µmol/m2/s has been noted as an optimum for growth. Less than 500 µmol/m2/s and growth will be slow. Plants require additional CO₂ to utilise more than 1 000 µmol/m2/s.

@Za Weed Lover 2x2m I would want at least two 1000w hps or 630w cmh'sin there as a minimum.

 

Personally I have switched to Quantum LED's for 1.2m areas in the following config:

• 3x Samsung LM301B 3000k and 3x Samsung LM301B 4000k driven by a Meanwell HLG-320H-2100C to 320w
• Supplementary Red Cree PCBs at 130w powered by a Meanwell ELG-150-C1050A

This combination for a 1.2x1.2m,  with up to 2.7 uMol/J efficiency if you running the Quantums on a dimmer.

It can however be pricey to buy, if you can however source the parts yourself to build one or two it will work out cheaper in the long run than an HID. It will also help control the temperature in your grow room, as it does not put out close to the same amount of heat as an HID light.

If you want me to point you towards where you can find components feel free to PM me.

How many LED's per board / bar / strip, the full spectrum 300k boards, 288?

 

Did you build these yourself? If so, where did you source the heatsink from or what did you do for a headsink?

[Dox420]

what is the best type of light to use ?

Nice set of lights there, plants will love them especially in flower. I got about avg of 1,4 g/w on simular setup.

@PsyCLown It's one of our old prototypes

If I'm not mistaken this is this dudes 1st grow. When I started it was pure simplicity at its best.

I asked a noob question and I got my answers from those legends who helped me in small steps to get where I want to be.
Nowadays a new grower gets thrown with info like above.

Not dissing or disrespecting, just amazing to see how the info and grows has come from my noob days to the nowadays noobs.

I still don't really care about technical side of growing.



This was my technical when I started

I was actully recently wondering how the fark people grew in PC cases as they're small and my plants are faaaar bigger than a PC case. In less than a month it would have outgrown the PC case.

 

How do you do it? How much yield do you actually get?

 

 

Times are changing and things are evolving. Naturally you will get some products which are better than others and with LED's in particular that can be hard to tell whats what as they can look the exact same, however differ greatly in performance just by using a new diode which is more efficient.

 

Compare the diodes on those cheap strips you get at a China mall to a Samsung LM301B for example - which is still up there among some of the best, cost effective LEDs for growing.

Nah dude I harvested like 10g at most but ended up going bigger and then it turned into a germination station. Most I would fit in there was 5 x 20w cfl's. Flowering times was fun times. Spend hours just looking. Still do but yeah at that time (for me) I was fucking stoked. But times have evolved and I'm now currently growing with a led aswell

Keep in mind that some people like the science  behind it, but it's not necessary to grow. It does make a difference to know what to look for when comparing different lighting options.

I personally like the science behind it, helps me make a more informed decision.

 

The problem with LED's is that an LED light is not an LED light.

 

If you compare 2 LED lights, both with an total draw of 240W from the wall for example, both 3500k for example. The results you get can vary greatly between them!

A CFL is a CFL, an HPS is an HPS. The same does not apply to LED's, it's all about the diodes. Gotta compare the diodes with one another.

Thanks for the help, did finally setup my indoor grow. 5 weeks in and just filped to flower. Bag seeds. Using Screen of green. Feeding compost tea,kelp and grown in super soil. 

[PsyCLown]

I don't feel there is much need to feed kelpak once the plants are bigger. More for seedlings / clones.

[Za Weed Lover]

This is what my setup look like and currently inadvertently week 3 of flower . Question for the older growers. When would you stop scrog training?

Week 3 is normally the end of stretch. Depends on your strain though. What are you growing?

[Smelly Joe]

Doesn't it also depend on light strength, amount you want etc??? Reason I say that is because your screen isn't full yet....

I can't really talk along because I have just germed my beans for my 1st proper scrog try.

First run. All random bag seeds. 400w hps.

Cant go wrong buddy start a grow diary with the beans

Just a question regarding lights....

I have a LED light that covers a certain area. At this moment all my plants fit in under the bright light, but I was wondering can plants be placed in that areas that doesn't get direct light but a bit dimmer that direct. I want to use my tent to its full potential...

Sorry for the hijack...
