Neville's Haze, in search of a keeper

Do you mean literally lowering the light closer to the canope or the wattage of the lamp?

Im asking because I finished a couple of pure sativas last spring. I assume I had a problem with too much light around day 45 of flower but am not 100% sure.
Much of the upper canope was burned (though I was still able to take them to day 127 of flower and there was enough new growth in between to offset some of the damage). I would like to avoid that again.

Could you please enlighten me? :)

Beware of too much light.

Last year, because I was growing in winter and it was too cold, I made the mistake of using 600W HPS lamps as the only source of warmth and placed them vertically at 25 cm from the plants.
(It was so cold that even at this distance the temperature on the leaves of the plants did not exceed 24-27°C).

The problem wasn't the temperature but the light intensity, which was the double or triple maximum tolerated by the cannabis.
The result? All the females produced steriles seeds and the buds were good for trash.

(Sorry if I'm monopolising the thread too much).

Beautiful plants to grow. The best sativa dominant hybrid from Mr Nice for incredibly lucid highs resulting in deep healing and smiling faces. There is a sense of accomplishment that can come about from growing this variety. She can teach you alot about yourself as you put all of your growing skills to the test. NH does require just a little more attention to inputs. And they do require space and time. As @Swifty says, feed them N during veg and during their flowering growth surge. Then taper. Same with light, gradually increase intensity and then preferably put them off to the side out of direct light to finish. Reduce hours of light as they are known to keep producing pistils until you reduce intensity and duration. It is a worthwhile spiritual journey worth taking IMHO.

Sorry to hear that. A learning experience at best.

My last f* up happened during my second run with pure sativas. I havent had this with hybrids because I was using a lower light intensity and 12/12.

In preparation for the grow I found a lot of literature on how sativas want more light during flower (and this info to me seemed to signal that they need a shorter but more intensive period of light when compared to hybrids - which when considering where sativas originate from makes sense). I also found sources that claim that a more intensive light (among other options) will keep the stretch at bay.

Im simply going to have to monitor and document better next time.

I can't wait to test these 😄, I know you hold the NH in high regards and your grow is an inspiration for me and many more.
Thank you for the tips, I will start to lower the light hours more after the first budset.
The smells from some are just incredible and more than I was expecting so far.
It will be a nice wintertime!
 
Day 58 today of flowering.
I hope to be around the halfway point.

Light is now 10h45 on and 13h15 off, in 2-3 weeks I will bring it to 10h30 on and 13h30 off.
I will not go lower for the rest of the grow.

Since today I give them only Alga Bloom, 3ml/L for the next week.

The plants have completely taken over the screen, it is hard to see what is what.
This means that harvest will be a challenge.

Cool,

I'm a bit worried at the moment because I'm waiting to install a new dehumidifier. I'm in a new environment and it's a lot wetter than the last one.
But I can see that with the range of 50-60% HR your plants are doing wonderfully, so normally I don't have too much to worry about.
However, it's true that a strain that's close to being a pure sativa tolerates humidity better than the ones I grow, but I'm reassured nonetheless.
(I ride at around 55% HR too, whit a bit higher temps as i grow whit HID lamps).

Thanks. 👍

No problem, I would think that a HID will lower the RH a bit more.
Good airflow and keeping your wet-dry cycle in tighter margins is very important if you grow in soil and gradually increasing the feed as they grow is very important imo.
 
Here the humidity is very very high.
And what surprised me was that now, in summer, the humidity is even higher than in winter. (~80% summer vs ~65% winter)

And I've changed my containers from 4 lt to 7 lt, which increases the humidity even more, but everything should be fine.
Thanks again, for the advices
 
Did I get it right? Total of 19 females in three containers in 60x120 cm tent?
That's impressive! What is the size of soil container?
I can see you kept topping them multiple times after start of flowering? With a last topping was 42 days (!) after inducing 11/13?
You said your tallest girl was 110 cm height on Day 21 of flowering, even after topping them several times! How tall they are by the date?
Please correct me if I'am wrong. I am very interested in your grow, as my next grow will be 16-weekers.

Hello @helmsman,

In the tent I have 28 females over the 3 containers, some have more plants in them since I started with seeds and pulled the males.
These containers can hold 15L of soil.
This is an important factor, plants roots can spread far more than in a small container benefitting their overal health in the long run.

I still topped some today as they are getting too close to the light, these heavy sativa dominant plants can handle this with no problems.
The canopy is now maxed out around 155-160cm, to big but you have to work with what you have.
Insane if you see how big they were when flowering started, these are from seed so the clones should behave a bit more and I'm still tweaking their feeding.
I gave them a lot of N from the start of flowering until 2 weeks ago to cope with early yellowing.

Good luck with the upcomming grow and feel free to ask if you have any questions.
What strain are you planning to grow?

edit:

I've done this already with Mango Haze/IBL and Neville's Haze Mango before, here is a link to NHM thread:

Update: NH ♂️.

So I have 19 Neville's Haze males and these will be tested for trichome production and smells.
I would not pas the opportunity to evaluate these although it is a lot more work to for me.
I hope to find 1-2 exceptional males to make seeds with my current keepers next year.
Seeing how the ladies pump out trichomes I have high hopes.

The males will be forced flowered outdoors with 13h of dark to speed things up.
Every male is healthy and pruned, I made a new cut of each of them today as a back up.
I boiled the peat plugs and washed the plastic containers to avoid previous troubles with moulding peat plugs.

Did you mean testing for pollen production?

Because if a male produces a portion of trichomes like the females in addition to pollen, this could mean that the male has a hermaphroditic tendency and in my opinion this is not the best choice to use as breeding material.

Or are you planning to do a real test and cross them all with a "female reference clone"?

No Zero0, I do want to find the most resinous and aromatic males to make seeds with.
If they throw out any pistils they will be culled also!
In this thread you can see what i'm searching for (first post):

Isaacs Haze (AG13 x C5 (NL5 X Haze C male) 77-88 days or Top CC (C5 Haze x C5 (NL5 x Haze C).
This is why I am watching your thread carefully.
And I am impressed how you manage to keep your roots healthy at week 10(sic!). And this is happening while you have ONLY average 1.8 ltrs of soil per plant. Right? 28 females in 3 containers x 15 ltrs.
As per your grow diary you used only Alga Grow and Alga Bloom at very modest concentration. Yes, I remember some guano during veg. But anything else?
Plants on your photos are obviously happy, so I conclude your roots are healthy.
How you manage it in only 1.8 ltrs?
What is your watering/feeding style? I mean, is it a good flush with generous drain everytime. And then letting them dry?
Or is it liter or two daily?

Nice choice, seems like we are fishing in the same waters.:)

No, everything I do is documented here helmsman, nothing else has been given to these plants.
Strong haze influenced plants are indeed somewhat different to approach:

-Watering is more delicat, not to dry and not to wet (35-70%).
I give them around 1-1,2L every 24-48h, depending the ambient temperature of where the tent is.
This also keeps beneficial bacteria and fungus alive and thriving.
I never water with waste.
-Temps of the roots and canopy in check (roots around 20°C and canopy 25-27°C lights on).
-Start slow with the feeding, look at the colour of the leaves and the growth rate to judge when to feed what and how much.
-Most important is that it is better to have a light intensity that is slightly weaker than stronger.

Keep it simple and with each grow we get better at understanding them.
I'm far from an expert but I do love to grow.
