Thanks for your input! I dont necessarily think its a temp issue, ive kept vpd in check the whole time. They also grew quite rapidly and drank an average amount. Not too fast or slow. Ive been trying to dial back the feed and i think we just took that notion a tad too far. I have a K supplement for this next round. Well see what it does for us. We use an anemometer to make sure wind speed is in check so we can rule that out. Overall i just think we waited too long to add hydroplex to our feed. When weve run it earlier in the past we didnt see the K def. If you look at some of my past grows you can see they are typically very healthy. Anyway, live and learn! Thanks 🙏🏻
I have temps range from 26.5C,78F to 31.5C,87F with leds and very high air movement and exhange. very dry air 35%-50%...I like leds with summer run cuz I have air cooled room.
At my place at summer air is very dry and air temps through day are mostly 23C,73F-32C,88F.
Only like that I have same transpiration rate with Leds like I have with Hids.

Feel free to watch and comment.
😊

Round 3 is officially under way. All before the last batch is even dry. Getting this cleaned and filled in 5 days is quite the chore but worth it. Wish i could be up and down in one day but no extra hands. Looking forward to seeing the weight from last run. Gonna buck that down soon. Temps at 80F, RH at 70-72%, VPD around 1.05. Lights at 40%. Well stay like this for the next 7 days then gradually adjust.

Clones always get taken while training for the flip to flower. Were on cruise control for a few weeks now…

Weight on first run, 15.3 units, this run is 29.3 untrimmed and fully bucked down after trim we typically see around 15-20% loss so favorably well see at least 23.4 units. It all looks badass. Still nowhere near the potential but this is very good. Its 1.48 GPW, if we were at full power the entire run. We gradually increased from 33% dimmed to 100% within 30 days. 65g per sq foot.

Hey Crooked, very good return please keep us posted on final dry weight but seems like 1kg per light! I think you can push even more too. I’ve been growing for 15 years my style is mapito flood and drain it’s loose Rockwool with coco flakes mixed through very good medium only issues is washing out at the end as I reuse it. Now I’m thinking doing cubes on slabs like yourself. Can I ask how many times do you feed how high do you flood also I take it you let plants root into the slab before flowering? Very curious as this would save me a ton of work I could probably reset room in a day if I did this method!

Cheers

We do not root them into the slab preflower we flip them that same day. Ive considered vegging in place for a few days, might be a good call. We flood twice a day at first, then down to once a day, then back to twice towards the end. And it flood pretty much up the whole slab.

Thanks for reply, i think i will give this a try next round i am currently at week 7 flower. i will do a journal once i start. So you preveg in 6" hugo blocks then straight onto slabs correct? Do you use moisture senors? What nutrients are you running? Thanks Snydgrow

4 in pargro. No sensors currently but i want them. Base nutes are house and garden aqua flakes.

Here we are at day 10 of flower. Really filling in nicely and I trained them into their second screen earlier this run. The net is definitely full. I think this will pay off. Adding a K supplement this run starting with this res change into week 3. Overall, very glad to see this cranking this way. Leaf temps 78, rh around 60-65 and co2 at 1150ppm.

really enjoyable read this so far, looks like your even more dialed this time round.
would you care to elaborate further your theory on the plant not having enough k at the early flower stage and due to this, the plant sends this back down to the roots which causes an acidic reaction in and around the rhizophere. I'm quite familiar with these findings of yours and wondered if you could actually say without a question of a doubt this theory of yours is 100% correct
many thanks in advance

I learned in bugbees course about this in reference to P not K. And its true that they can acidify their own root zone quite a lot. This is in attempt to search for P and what happens is they take in too many micros and you can see toxicity from them if not corrected quickly enough. If your plants are overall underfed and youre seeing your PH drop its likely this is what is happening. Just letting you know this is not a theory or my own findings these are proven through the utah state university cannabis research team.

I hear what your saying mate and thanks for the response as I'm hear to learn as always, I find it quite fascinating that a plant that as plenty of food stored in itself,actually sends this back down to its roots.i know what the university is saying but I tend to look at it from a different angle and that is that if I'm eating and eating then I tend to get rid of it . as you know I'm talking shit lol
so we will leave it at that and I'll go read some university papers. I always thought a plant due to millions of years of survival instinct would collect and grab onto what it needs for future use so why send it back down to the roots only to utilise and take back into its frame again. me personally wouldn't want to eat my own shit but I guess a plant must be different from what the university studies telling us?
I've always took a differing approach for example I know that around the end of stretch frame building period then the plants hormones change and realiase that its ready for stage two of the flowering phase.why would what you know comes natural after eating, keep eating/ forcing it down you if your bodies not getting rid of the waste and repeating the whole process of utilising the nutrients again.
Well that's enough shit talk from me for one day

“A plant that has plenty of food stored in itself”
- what do you mean by this? Plants dont just come loaded with food already. They store nutrients but also mobilize them. They are only able to do this based on what is in their feed. This is why tissue testing is helpful, so you can see a breakdown of what they actually have in their tissue vs what you are feeding. Its important to know which nutrients are mobile vs non mobile, i highly recommend researching this.

“Actually sends its down back to its roots”
- youre misinterpreting what im saying i think. The plant is not sending feed back to its roots, its simply acidifying its rhizosphere seeking to make nutrients more available. None of the nutrition is being sent back down to the rootzone from the shoot zone

“If im eating and eating i tend to get rid of it”
- firstly, you are not a plant haha. Second, plants arent digesting their food and excreting waste like you. You cannot compare the function of your digestive system to a plants nutrient uptake.

“I wouldnt want to eat my own shit”
- again, you are not a plant and many plants tend to love eating broken down shit/manure hahaha. But in this instance, again, they arent reconsuming feed at any point that they returned to their root zone, that is not what is happening here.
