Hear, hear. I started with Botanicare "expert" line because I wanted the best nutes for my plants, doncha know. That lasted three grows. I've still got the pretty bottles. After grow #3, the light came on that it's all the same 18 chemicals and narrowed down my choices to either the GH three...

Glad to hear that!

If you can get RH down into the 50's, do it. I lost a really nice plant to bud rot a couple of years ago and it really suck to see almost 4 months of work in the trash can. Re. bud washing - I started doing when I had to use a spray for thrips and I've made a habit of it. It doesn't harm the...

At three weeks, most plants have four nodes ('cause day 21 is usually when you top them). Is this the plant in another thread? It looks OK but not highly developed.

I don't see any issues with light, either too much or too little. The yellow coloring of the leaves looks like a nute imbalance so it could be a nutrient issue or temp+RH or something else. Post some into about the model of the light, dimmer setting, and hang height as well as nutes you're...

My first modern LED was an SP 3000 and Coco was one of the reasons I bought it. It will definitely get the job done!

Excellent! That's a super product. @ptrgrow has been good enough to post the PPFD map for the XS-1500 and the XS-1500 Pro is shown here. You can see that with the new light, the hot spot that the old light had in the center is gone. The older model had a higher PPFD right in the center but the...

Yeh, the "light curmudgeon". ;-)

I would not use those lights unless I had no other option. In a small grow space, I would go with the Vipar XS-1500 Pro. (checks the OP's message again) - good you have a Vipar. Is it the XS 1500 or the XS-1500 Pro? I've got the 1500, which I bought a few years back, and the Pro is a far...

No reason not to top autos. They're just a cannabis hybrid. It's not that common a perspective here on RIU but another site that I frequent has a much older demographic and many growers there speak of autos in a very negative manner. My understanding is that the earlier "versions" of autos were...

I get that. A filter for Photone is $5, a light meter is $32. We don't really need either - a lot of people cannabis grows turned out really well without either of them - but better equipment allows the grower to make better decisions. Two caveats - that's personal bias from a long time software...

"phone already calibrated" - meaning that it's one of the phones for which growlightmeter.com has published results? That's great! "So I just needed a bit of paper to diffuse with." - without the diffuser, your readings will be…100±µmol low. That's my main concern about Photone. He's not...

I recommend against using Photone unless you can calibrate it. I've tested it twice. It failed to give a result when I tested it against a blurple (in 2021 when the app was called Korona) and again a couple of years ago when it read 16% high. I understand what the programmer is trying to do —...

Your leaves were not "canoeing" or "tacoing". I don't see any indication that levels were excessive. What am I missing? Drop $32 for a Uni-T light meter and check out the document that I wrote on converting lux to PPFD. Cannabis is a light whore loves light and will thrive at 800-1000µmol in...

Wow, that's looking great!

Fans will move the moisture laden air around but it won't drop RH. According to the folks at PulseGrow, lights out VPD is nowhere as important as VPD when lights are on but they do suggest you try keep it close. I forget how "close" close is but I think it something like 0.2. If you're not...

I've grown plants 50"+ in 4" net pots and I can't quite get my head around how large the net pots are for these systems. The only downside to a 4" net pot is that the trunk of the plant grows so much that the net pot bulges so I have to cut it apart. If there's a 5" size, that's the one I'd go...

Thanks for the info. I'm more likely to go the Fallponics route if I take the leap. I really light not having to deal with swapping a res so I like the larger volume of the Fallponics.

If it's the Electric Sky 180 V3, your light is generating a lot of photons in the center of the light but light levels fall off very rapidly so you need to get the plants out of the hot spot. The PPFD map is from the product listing on Amazon. I do see a lot of leaves that are "praying"...

Great, you've got a dehu. Check the image of the VPD chart that I sent. You're in early flower so you'll want to set a VPD of 1.2 VPD is the difference between the water "pressure" in the leaf and the water pressure in the surrounding air. To be calculated accurately, you need to know the...
