How Much Will I Yield?

[mikeberg090]

Actually I also have the same question. Initially I was so confused about buying the right grow light when I read some reviews on the web. Though, I thought that the main purpose of the website is selling Amazon products, still, I thought to give the Viparspectra 600W a try for my 10ft X 10ft grow room. I am using external exhausts in my grow room. Still, I am soon starting with the second unit and I would need suggestions from your side. Should I again buy the Viparspectra or is there any better light than that? I prefer to buy the light through online shopping only. Please suggest guys!

Actually I also have the same question. Initially I was so confused about buying the right grow light when I read some reviews on the site 15 Best LED Grow Lights Reviews for the Money [June 2018 Updated].

Avoid the viperspectra. I started with them also in a 10x10x7 area. I used 2x1200w viparspectras and 2x300w and they weren’t enough to run a 5x10 area. They are only rated for 3x3 to 4x4 max and the further you get from the buds the smaller and less dense the nugs will get. I know you asked months ago. Their are better leds for sure but they are pretty pricey. If you wanted to fill that room properly with 1200w leds(like 540w at the wall) you would need like 6 of them. I now use the leds for veg only and hps for flower and the nugs under the hps are much denser and larger in general.

How Much Will I Yeild?
"I have XXX watts...how much will I yield?" or "How can I get bigger yields?"

A common inquiry. From ambitious new gardeners and for good reason too. But, this is really a loaded question that doesn't have a definite answer. It seems one of the first assumptions by new gardeners is that loads of light automatically equals loads of buds. Unfortunately, it's just not that simple. Yield is equally contingent on a number of factors; light, temperature, humidity, water, nutrients, CO2/ventilation, genetics, etc. Think of it as an engine, with each factor of cultivation representing a single piston, sure the engine will run if some of the cylinders are misfiring or not firing at all, but to yield the most power from that engine, all cylinders must be firing in sync and at maximum capacity.

Temperature. Most cannabis plants will slow or cease growth when temp's get above 85F, or below 65f. Optimal lights-on temp for most strains is about 72-78F, with 5-10 degrees cooler during the dark period being a good rule of thumb.

Humidity. Cannabis does best around 45%-55% RH (relative humidity).
During veg and late flower, however letting it drop lower during the final two weeks of flower is advised, as it will help prevent mould problems.

Water/moisture. Cannabis generally doesn't like "wet feet", or a soggy environment, so it's very important to have a fast draining soil/soil-less mix (or well aerated solution in a hydro garden). Wet or damp conditions can also lead to mould problems during flowering.

Nutrients. Cannabis will require a variety of nutrients at varying NPK ratios during its existence. NPK stand for; nitrogen (N), phosphorus (P), and potassium (K)-the three major nutrients used by plants. Simply put, your plants will need a fertilizer with more N than P and K during vegetative growth and fertilizer with more P than N and K during flowering. Using any well-known quality fertilizer applied per instruction @ ½ strength is a good place to start. Organic, chemical, or somewhere in-between is another choice to be made and is a totally personal one. There is a plethora of fertilizers on the market, but the best fertilizer is the one that's used properly.

CO2/ventilation. Plants require CO2. There is sufficient CO2 in our atmosphere to support massive bud growth, but when growing inside you must either have adequate ventilation (the volume of the room exhausted at least once/5 minutes) to ensure that there is a constant supply of fresh, CO2 enriched air or one must have supplemental CO2, which requires higher temp's and more nutrients to be utilized effectively.

Light. Typically, the more the merrier, but more light will create stronger water, nutrient, and CO2 demands on the plants. You must also have the proper spectrum of lighting as well as a means of efficiently reflecting as much of the light as possible into the garden\'s canopy. The norm is to use more bluish light (Metal Halide, cool-white fluorescents) for vegetative growth and more reddish (High Pressure sodium, warm fluoro's) light for flowering. Though it's possible to grow great buds under fluorescent lighting and a few will even argue their superiority to HID's, most indoor growers use High Intensity Discharge lights such as MH and HPS, and many use fluoro's for vegetative growth and HPS for flowering. It's very important to have the light as physically close to the canopy as possible without burning the foliage and still allowing for even coverage.Many new growers believe that "Droppin the light" closer to the plant will be beneficial. Besides heat stress, the bulb puts out radiant energy that causes leaf burn (Note it is possible to complete a grow using just HPS or MH)

Genetics. Its an easily overlooked factor. Some strains simply have the potential to yield more than others. Having a heavy-yielding strain doesn't automatically equal big yields, either. It only means that the potential for heavy yields is there. The grower must provide the optimum environment for that particular strain in order for it to be able to reach it's yield potential, and each strain has slightly unique requirements. Also, within a strain there are usually several phenotypes, each of which will exhibit unique characteristics which is to say that some pheno\'s of a particular strain will weigh more than others.

Plant/root/container size. Obviously, the longer a plant is veg'd, the bigger it will get and the more it will yield. Almost always overlooked because they're unseen are the roots. Root mass is directly related to bud production. Simply put, the more roots you have the more bud you will (potentially) have. Be sure to always allow plenty of space for the roots to grow and spread out, even more-so in soil A general rule of thumb is 1 gallon of soil for every foot of plant height.

System.
Scrog/Sog/Vertical gardens
These systems have a higher g/w/time yield than comparable large plant system over the same time period.

Grower's skill. Growers can add yield by: using additives (like B1, kelp, enzymes), foliar feeding, and topping/FIM/

In addition. Tricks like keeping nutrients and the air temps warm during night cycle can help final yield. Although it's a topic of hot debate, it's generally thought that any system that supplies the roots with maximum oxygen (aeroponics) would outperform a system that restricts 02 input such as (soil).
So, as you can see there's much more to yield than throwing some plants under tons of light with tons of nutes. Before one becomes too concerned with yield, one must first learn how to grow plants well, learn how to "listen" to the plants and give them just what they need. It's best to start with simpler methods, in fact, I think the simpler method is always the better one. Learn how to grow strong, healthy, fast-growing plants and the yields will come.

Great info there friend

I don't consider the brand to be a top-shelf one, but insufficiently illuminating a 100 square foot grow falls under user-error.

Of course, it's easier to make such an error when a company advertises a 40-watt device as being a 26,400-watt one - which is a big part of why I don't like the brand. If I started advertising two-liter bottles of soda pop, but only poured 16 ounces into each bottle, I'd (A) go out of business and (B) probably be guilty of breaking some kind of consumer fraud law. So that'd be on me, then.

On the other hand... Any poor schmucks who ended up buying my pint-sized "two-liter bottles of soda" at least would not go around telling people that they had two-liter bottles of pop. It's like when CFL bulbs were introduced into the mainstream all over again, FFS. "I got me some hunren wot CFL bulbs, gonna stick four of 'em in a box to grow me some rope, yeah boy. 'Cause my friend has one a those 400-watt high presser soadum lights and he's harvesting buds alla time."

I love my Viparspectra. It's just as quality (probably better) as any of my other Blurples. They don't claim anything that the other LED manufacturers claim, they all use misleading nomenclature. A user just has to educate themselves about what they are really buying. Mars Hydro certainly has strepped up their game with the new white light but VP obviously does something right or they wouldn't be so big. Did you know they are a sponsor? It would be great to have a rep around like SS from MH to talk up their products.

No, I didn't know that (at the time of my previous post). If I had known, I might have thought about wording my post a little differently, lol.

I wish that every forum sponsor had an active forum representative. It would potentially benefit both the businesses and the members, assuming that the various reps didn't start sniping at each other.

maintaining a forum presence beyond sponsoring can be a slippery slope for businesses. there is always a negative vocal segment. look how many sign up just to gripe about some product or other.

Can any one give a rough idea of yield:

3x3x2 tent. 4x600w hps. Rdwc 16pot system.

With good conditions and no problems can any one tell. Does 500g per sq m sound about right?

2kg???

Any help appreciated. Cheers boys

 

[Pbass]

2kg???

All that in a 3x3? Easily! I'd love to see that setup!

 

[Chris Scorpio]

Are u talking 9'x9' x6' area

And yield is based on your growing talent more than anything

 

[Bigeef]

Well I will be putting some pictures up because I am going to need some help 4 sure. How many times would you top and train the plants in that set up for the most effective grow?

 

[Ghostwriter31]

ok.... but around how many ounces does an indoor/soil plant usually produce? ive looked through the journals, but no one seems to say how much weight they harvested...

This all depends , but I’ll say that I’ve grown out 6 female plants , my first two grows , and my yield was around 4 ounces from each plant. I’ve seen first time growers yield a pound from their first attempt. This is from indoor tent grows. Outdoor grows can yield several pounds a plant.
id say that most first time growers yield anywhere from an ounce to a pound
But as most others have pointed out, your environment is the most crucial element to growing high yields , that with your genetics

EDITed,because... I'm a dumb@ss and confused meters for feet.

 

[bluter]

2,400 watts of HID lighting in nine square feet of garden space?! My guess would be zero.

just saw that .. good catch ts .. would be a tad sweltering ...

oops ... yeah i smoked one too .. or is that two ? three ? ?

 

[TorturedSoul]

I don't even have that excuse - the only thing that got smoked in my home today was... my freezer . And some recycled tobacco .

I'm just an idiot. For example, I took a nap earlier so I could stay up and watch Babylon 5 on COMET via stirr.com. Because I forgot it wasn't a weekday (night). Sure is quiet outside in the wee Sunday morning hours. I haven't even heard a vehicle go by up the hill on the highway for the past ten minutes.

trade ya in heartbeat...


my plate got stole then clocked doing a buck 40 ... then had an adventure at armed robbery, all on a near identical vehicle. they swapped plates a coupla weeks ago .. so i didn't know till just officers present at my workplace with stern expressions and loose weapons ..

i'm going to court over it .. with the support of the same officers for a change ...
