Thank you for posting this video. I watched this series of videos by Apogee a while back and this was a good refresher. Anyway, it's a big subject. If you check minute 13 of the video, this is close to what I'm talking about. I still believe that for flowering plants, the spectrum of phytomax is...

Yes it's very similar, that's why I suspected it's a phosphorus diffeciency. Anyway, hopefully it's just a PH issue with you. Keep us posted.

Oh man, I got reprimanded by soil growers in here for giving advice on soil while I only grow hydroponics :wall: and yes, they have a point. I don't know about Miracle Gro soil and their slow release of nutrients (or as someone in here said, they release nutrients when you add water). All I...

No, I think they have a better spectrum than HLG 550 and strip lights which use a full spectrum LED chip. Those LED chips, I believe, are not optimized for flowering plants and that's why they add deep red to them. Having that much green amounts to just wasted power in the green spectrum. But on...

I tried to do some calculations right now and it is much harder than what I previously thought :D, needs more reading and research. Anyway, please be very careful with those my friend, I assume you manually turn them off before you open your tent. 280nm is actually considered UV-C which gets...

Oh, you living on the southern hemisphere really is mind bending for me :D. When you say that your peak summer starts at 21 December, that's peak winter for me! Anyway, you seem to have everything figured out, good for you! And have a wonderful grow my friend.

Yup, it's all about the positive energy :D So what you do is you monitor your plant. If at the start of Week 7 it really seemed like it's finishing up then by all means give her the Week 7 nutes as per your feeding schedule above. But since I doubt it will finish this soon, then you just keep...

Price-wise absolutely not. Light spectrum wise for the plants, yes they are better than the HLG and other strip builds. Edit, this doesn't justify their price by any means though!

Oh that's pricey but I think it should be effective. I have a question on the technical side if you don't mind, did you try to calculate the umol/s of those UVB strips and try to match them to what the sun provides at the UVB spectrum? I mean, aren't you afraid that you might be going overboard...

Well then, you're ahead of the curve my friend :D Amazing looking tops! and you seem to have a mix of light types in this tent! So how much did you pay for these UVB strips? Also another question, how much watts per square foot would you say you have in your grow room?

Yes exactly, didn't know they made them in strips! are these yours?

Well as you can see here, the light you linked is only 95 watts. Your area is about 5 square feet. You should strive for at least 40 Watts of actual power draw per square foot which amounts to 200 Watts actual power LED. Any 200 Watt actual power LED grow light will be good for your situation.

Surely they have a huge profit margin on it. Almost non of those LED manufacturers actually do credible research. Research is done on best lighting for the plants and is freely available everywhere. Those manufacturers just followit. Like for example, years ago they had only red and blue...

Lol, well that's why I said I wouldn't buy it myself, it's very pricey. No, for a price of about 330 dollars, this kingbrite light is not bad actually. I initially thought you were talking about Eco Farm strip light which is about double the price. So yes, go for it.

Yes Very nice setup and a really nice studio. So yes, I have two thoughts. First, for a stealth setup and your friends coming over and not wanting them to notice anything, did you forget about the smell? You should really get a good carbon filter man if you're going for a complete stealth...

Main problem I see is your light power. With 108 Watts actual draw, it's about 20 Watts per square feet while the recommended is 40 Watts or more per square feet. I have to tell you that your yield will greatly suffer because of it but if you are fine with that then okay. I just find it a waste...

Do you mean between those two or in general? If you're talking in general and without talking price :o Well in this case I can recommend a light that I myself wouldn't dream of buying lol. https://www.blackdogled.com/phytomax2-400.html Go through this link and you will find great information...

Not to discourage you by any means but I would be really impressed if you could achieve two things: 1- If you were able to finish this auto-flowering strain in just 8 weeks. I doubt that very much indeed (and the last week is only flushing which makes this grow 7 week only). I think it will be...

There is a huge price difference between the two! you have to be more specific which lighting you're talking about. I assume you're talking about 'HLG 550 V2 R-Spec' which is geared towards flowering and full cycle and the "ECO FARM 480W Samsung 561C chips LED grow light strip". Honestly they...

At first I thought it can't be this way but it turned out to be exactly this way!
