I have managed to maintain the heat within a EASY2PROPOGATE system from Autopot (pictured below) at a steady 24C in a room that was easily dropping to below 10C. I placed the mat under the propagator, connected to a Sonoff and it worked like a charm. I don't think it will work well for anything else though. I think the heat would dissipate pretty quickly in a larger environment like the inside of a tent.

How many hours can this setup provide you?

Snap actually

A common oversight indeed. One forgets how big these girls can get when grown outside and for the maximum veg time, almost rediculous. Shame but then @Sorrowless101 is going to have to wait even longer

Oh there are definitely purists around. RO has it's uses but not on the scale that we are growing. If you have 1000 plants in a facility that has dialed-in feeding schedules and they all pull from the same set of reservoirs, you'll probably use RO water to ensure consistent results and outcomes across multiple seasons. Didn't even consider @KLS's phone would have been lighting up while we burning that midnight oil/dab/vape/kush

Bru when I first started meeting other growers on the scene in JHB (excluding the ones I've met here on the forum) they were all OG Cape Town ballies that moved up to Jozi. Haven't quite figured out why they decided to come this side, maybe the scene changed in CT over the years

I blast tap water from a hose into 25L containers and let sit with the screw tops open for a minimum 12 hours but preferably 24 hours. I try to create as much aeration and disturbance of the water in the containers as possible. I believe this method to be of the "good enough" variety.

At the end of the day you won't have a problem. If you use hard water nutes in soft water you're only really at risk of calcium or magnesium deficiency, and it would be so minor and such a quick fix. You'd either just add more micro or do as @TheUltimateNoob says and gooi in some epsom salts.

Careful with this distinction. Tap water in CT is hard, tap water in Jozi/PTA is soft. My tap water comes out at about 40ppm TDS. I personally use soft water nutes from GHE and have gotten it nailed, adjusting for deficiencies/toxicity has gotten better over time.

...choo choo

All-in-one ching chong. After this grow the smaller tent will be straight-up veg and this bigger tent will just be flower.

Sjo howzit. I'm ready to share what I've been up to since the last grow. Right from the get-go, I know this setup has flaws. I've got two different kinds of lights, three different strains and two different growing methods. I'd like to say this is on purpose but honestly it just kinda happened. Somewhere between an upgrade and circumstance I've now ended up here. I've decided I am going to do one last hoorah with DWC, going back to my roots from when I first began growing and also use the HID lamps I've had tucked away since acquiring my LED. I really like DWC, it's hellah fun and technical. I just love the amount of control you have with it. However I really want to do a serious ScrOG attempt next and the last time I did a ScrOG it was with DWC and couldn't even finish that grow If not DWC with a ScrOG, what medium to use then? I've never grown in a solid medium before so I'd have to learn soil/coco. So I decided to throw in a couple plants in Freedom Farms Premium Classic and have them grow in the space I had left in my tent aside from the DWC setups, so that I am not a complete n00b when I do the ScrOG. Did I mention I got a bigger tent? I am now rocking a 1.2x2.4x2.05 meter tent and oh boy, I think a ScrOG will do just super.. but that's next time. Why waste time and not just do the ScrOG now? Well, I've got some very nice seeds on the way (enough time for another grow) and I'd like to create a mother from that pack of seeds and then use clones from the mother to fill the ScrOG. I also do not feel like my previous DWC grow was very good either, so I want to get a solid one in before dumping the buckets. The plan is to do 4 DWC cooler boxes, same design as before. They will have 250W MH to veg and 400W HPS to flower. The ladies in the DWC will be mainlined into 8 queen colas each and I am going to be extremely aggressive on the defoliation. No kak cheap branches this time with poopy airy buds. I want 24 thicc and solid queen colas that look like the Grinch took a shit on my desk.. multiple times. After setting up the 4 DWC systems I couldn't help but notice that I had a third of my tent unused. I had already gotten a few extra things to expand my HID lamp setup to accommodate the increase in DWC buckets and number of plants, so I don't want to invest in more HID power. I want to keep the power below 1000W in the tent, I don't think anything more is necessary for what I'm doing. Although I have my 250W LED still, so I decided to just throw that into the tent in the unoccupied space and do two plants of the same strain in soil to learn the ropes. The two plants in soil turned into five plants.. during the propagation stage one seed didn't pop, so I decided to pop more seeds to compensate and got a little paranoid and decided to pop more than necessary in case some didn't germinate.. they all germinated. So now I have five plants in soil, 4 of which are the same strain, 1 is a very long flowering strain. Once again I have done this to myself, putting different strains with different flowering times in the same tent. But mama didn't raise no simp so imma let them finish as is. But bro why not use the 80x80x180 tent you have sitting empty now? It's way too cold to veg under LED and no heating. The beauty of HID lamps in Winter is that you get your photons and a comfortable temperature in your tent all in one! So I've just put the soil plants under the LED in the same tent so they can share the heat. I did however add a small heater with a Sonof switch just to help the temp with the dips at night and these wacky cold fronts. Also because of the different flowering times I can then use this smaller tent as a drying tent as a harvest. Even better, if the 5 soil plants get too big in their corner I can just take a few outside to flower Strains!

Please do not be shy to continue updating us on your grow as per usual. We are here to see your ladies

I had a similar thought when I bought my bags of FF Premium Classic. I had also at the time had a bag of Organic Matters Living Soil. The FF soils seem way more coco than.. well.. "soil". Even then though I am myself using the BioBizz range and so far so good. I rate as long as you watch your plants, don't over do it, stick to the feeding EC, you'll be good with whatever.

@TheUltimateNoob https://support.bluelab.com/hc/en-us/articles/205237090-what-are-the-different-conductivity-scales-what-do-they-mean-

Think the dude just wants confirmation and confidence on a nutrient feed for his medium, the FF Formula 1 to be specific. @Burly I'd forget anything to do with ppm and just stick with EC. Did you know there are two different conversions for ppm and they are dependent on country? EC is just way more universal and prevents any miscommunications. They'll obviously push their own products on you first, so just keep that in mind. Good that they do provide an alternative for you, although you could also just use the normal GHE Trio and just add additional calmag to compensate. Notice what they are saying here. They are saying that if you wanted to 'add' organic nutes you would need to lower the strength of the synthetic nutes. Is it reasonable to then say that they mean you can't just use organic nutes? I'd find that interesting.

I'd guess discolouration, droopiness, stunted growth and/or bad vibes.

https://www.420sa.co.za/topic/3961-led-advice/ @CreX he's posting in two threads about this LED. He said he could get this LED for R1k, otherwise he would DIY with a what seems to be a 100W Meanwell driver and what I would assume would be LED strips. That LED he's posting about has 130W draw from the wall, so I'd have to say for a grand I'd go for the LED over DIY.

You've asked in two places about this lamp. Please try keeping it on one thread. https://www.420sa.co.za/topic/3973-curly-brown-edges-on-leaves/page/2/ I'll post again the information on the lamp for sake of ease. https://www.aliexpress.com/item/4000778042225.html?spm=a2g0o.store_home.singleImageText_75985406.0 It's a 130W QB using generic SMD LED chips. Definitely not 400W. Better than CFL. For a grand it's better than most CFL setups.

Probably just in terms of lumens per meter. 3000W of HPS (3 x 1000W HPS) in terms of yield will absolutely decimate this LED no doubts

In future consider starting your seeds in a smaller pot then moving them when they are more established to these bigger pots (assuming your Putins Punch seeds are photoperiod). Also fill up your pots more. Only leave like ~2cm at the top from dirt to rim.
