Small fluffy buds

[coreywebster]

One thing im wondering, is it my eyes or is the top of your medium covered in dead leaves?

Anyway, back to the point, if you pide a plant to create so many tops you get smaller buds across all those tops than you would having half the amount of tops.
The other thing to point out is its your first grow with this light and your just at the halfway point of flowering.
To me the light does not look good quality, it has the price tag of quality but makes all the claims a BS light make, saying it replaces 1200-1400w of HPS is a sure sign of bullshit. Claiming it penetrates 5feet through the canopy, I mean how would they know that? Is every canopy the same density? Just daft statements and claims..
That said if its 540w or whatever it should flower fine in the space its in.

Are you experienced in growing with other lights OP?

All leds make claims thats the problem, go buy some hps or t5 and none are making claims just pretty pictures and at best one of spectrum graphs.

Just got some t5s, no claims of anything just a lumen rating in very small.

Maybe so but some actually do what they claim and some don't. The genuine ones say 400w is equal to 600w HPS.
I was looking at the efficiency of t5s the other day and was surprised, they are very close to HPS.
I have seen these G8 LEDs before, still using chips from 1998 and selling them at 2018 prices.

They are in week 5 and are fast flowering plants 6-7 weeks. I’ll try lowering the lights than

Also I totally forgot to address this comment.

I don't know where you got 6-7 weeks from, but both of those strains take longer. All the Mazar x Rhino descriptions I've found say 55-60 days which is 8.5 weeks in a perfect grow with the perfect phenotype. White Widow details all say 9ish weeks, but the phenotype I ran for 4 years needed 10 weeks to ripen.

Now are you at 5 weeks from 12/12 or from when you started to see flowering happen? This is an important question because it completely changes your time table.

Plants don't just instantly start flowering when you switch the lights. It takes time for them to transition between stages. This typically takes 10-14 days, but sometimes longer depending on the strain, phenotype, and genetic maturity. IE: A seedling will take longer to begin to flower then a genetically mature clone of the same strain and phenotype.

So depending on when you started counting, your plants could really only be 3 weeks into flower. Which would have them looking great for their age

There are VERY FEW plants that will actually finish in under 7 weeks. I won't say there aren't any, I'm not some all knowing canna god lol. But seriously in the last 15 years of growing I've only seen a few plants look finished that early. Either in my gardens, friends gardens or on the various forums here online.

There are lots of people that chop plants early.....Many of them later complain the weed wasn't good...

Lots of breeders make false claims...but some just have super duper special phenotypes that no one else ever sees too.

All lights apart from your own leds are crap....

We get this a lot from led growers, let me just say your crap for crapping on lights here and making such a toxic tone.

i dont know about you but my leds are not all that good as i said ive made that mistake my self. some leds are really good. pink leds not so much

T8's are more efficient than T5's.

No 400watt led equals a 600watt hps.

Good lights dont make claims they assume the buyer knows the specs and what they can do, leds need claims because they sell to noobs

That's funny because your wrong. T5 is more efficient than T8 as far as lm/w goes.
560w of my LEDs beat 900w of HPS that I used to run.

I Grew for 18 years with HPS and last 2 years with LED. 10 crops a year perpetually for the last 8 years solid.
You haven't even tried growing with LED tech of the last few years, you know the ones that are 180lm/w.


Old lights don't make claims because they have nothing to claim against. They cant say compared to incandescent or to Halogen because they never got used for growing in the first place. The only thing they can be compared to is the sun been its the original grow light but they are not beating that so no claims can be made.

I have 400watts of Vero v7s form Timber Grow lights. And a 100watt Cob form mars in my 3x3. That light can grow rocks.

No T8's are more efficient lm/watt its just that T5's have more wattage hence there popularity and extra light.

Lumens per watt is not an accurate scale of light just one of the many which we try to judge light. The claims leds make are based on incomplete science but youll never understand that because.... yawn

To bring the spectrum of leds in line with hps you wont get the same efficiency, your still stuck with incomplete spectrum spawned from blurple days and your terrible science then as well.

Fuck do i care, any light will work but your led claims wont, they get argued many times and if they did what they said on the side of the box there wouldnt be an argument but clear consensus.

None of this ever sinks in with you guys but i do get some ego issues from time to time.

Well I tried googling that light and a Casio watch came up, G8900?

Without the specs I can’t tell if your light is the issue.

I know high temps can cause loose buds, but yours seem to be okay.

Your lights seem high, but then again can’t tell without knowing the specs.

Take pics without the lights on FYI next time.

Blurples can grow awesome bud, so don’t be discouraged

They all started flowering literally day 6 from 12/12 switch. Many white pistols started showing. I’ve had the lights at around 22inches and just lowered them and added a 600w Viparspectre led the par value read at 1900 par from 18 inches and the sides of the canopy read 1400, which is the least amount of par read in my tent. Would all of you say if my plants started to turn yellow and brown from the top that I have light burn. Just in case if I see those colors on my leaves

Day 34 of flowering 7 days ago from today 12/6/2018

Efficiency / quality of light
When talking about the efficiency of both lights the T5 ones are definitely superior to T8 lamps. They have greater lumen to watt ratios which means that they output brighter and more powerful light per watt of electricity than the T8 do. The T5 lamp light also is more concentrated and focused in one area because they are smaller in diameter (there are more watts per cubic centimeter in them) so the T5 bulbs are especially good for plants when they are flowering because then they want more intense light. And the fact that the T8 bulb light isn’t that powerful means you need to put the plants closer to the bulbs to give them all the necessary light. But if we speak about the actual quality of light then although the light from T5’s is more brighter and stronger the T8 lamp light have less glare and therefore it is a bit more qualitative for humans but almoust the same for plants.

A little tip: If it is hard to understand the difference in efficiency then here is a little comparison. A 4 lamp HO T5 fixture can replace a regular 400 Watt metal halide or high-pressure sodium fixture, whereas to replace it with T8 fixture you will need a 6 lamp

That's awesome then, if they only took 6 days to show flowers then they were nice and genetically mature when you flowered them. You should still count your flower time from that point though, not the 12/12 switch, that's 6 days of difference. That being said as I explained above actual total flower time is very relative to strain, phenotype, and other grow conditions. Based on several of those things, your about half way through your grow with these plants. They are gonna change a lot the next several weeks!

I think the added light and closer distance should be a great thing for you. Personally I've never seen "light burn". I've seen light bleaching where the buds will basically turn white on the tops from intense light. I even had it happen once when once plant got to tall and was almost touching the glass on my 1k. It was probably 10 total inches from the blub through the glass. The tips turned completely white at the top, but the rest of the plant finished growing great. I've watched guys use LEDs literally inches from their plants, and they just used nice air flow to keep things comfy.

My 400w HO t5 has 8 bulbs.....

Oh on paper id agree with you but that data dosent take into account reflectors and that the smaller the tube the harder it is to get an even coating plus cover the ends with powder.

All data is a preset from higher ambient temps of 35°c for t5's which i dont achieve but do the 27°c for the better built t8's.

My company advertise a 6 lumen gain for each watt for a t5 at 35°c over a t8 at 27°c and from following the available reflectors i find the t8's to offer slight efficiency advantages duecto width and fitting of the widerctube.

Theres a reason tubes in cold places are enclosed due to this temperature luminous efficiency. Ten degrees drops luminous efficiency a few.

Ive yet to find an efficient t5 reflector, most companies double you up on the t8 reflectors and my lightwave units arent up to the standard of my flouro company which again sends a t8 reflector for a t5.

Whatever happened to the t4's and t2's, rumours of brighter flouros more penetration but that was a long way back?

 

[sero1991]

It wasn’t a light problem, in fact the G8 900 was too close to the flowers. A lot of light burn since I added the 2nd light and brought them down. Still have no idea why my buds are small?

 

[Thundercat]

Can we see pictures of the light burn? Any chance of some white light pictures of the buds, maybe with something for scale?

Are we sure it isn't nutrient burn?

It's only been 2 weeks since you posted this. Are the buds not getting bigger at all?

This is extra funny because you know literally nothing about science. You have proven it over and over, and yet you still like to throw the word around because you believe it makes you sound like your opinions have any merit.
The people with actual degrees in relevant fields consistantly laugh you out of threads.
Try this, go back to your shitty micro grows with your shitty low wattage HPS and let the educated adults handle the thinking.

I don’t feed nutes only compost tea since the plants are in an organic super soil. I know it’s light burn cause all the top fan leaves have turned yellow while the lower half is still green. Actually there was one plant who was getting so much light I had to harvest it cause it had no more fan leaves on it and was dying with the trichomes being more clear :/ temps have been 60 nights 75 lights on humidity always at 20-30.

And no they’re still super small buds
