Sounds like you have a good plan there. Good luck! If the plants stretch like crazy, you may want to consider a 2nd layer net.

If the plants are small, such as seedlings, then the air in the 4×4 doesn’t need to be changed as often as large plants that fill up the 4×4 wall-to-wall. A general recommendation is to exchange the air every 1-5 minutes. Although, some people go longer than that and still get good growth. Hope that helps

This is a good question and I personally don’t have much knowledge on using carbonated water. Although, I do have an expert coming onto my podcast in the upcoming month and I have wrote this down as a question for him. Sorry I don’t have an answer for you; maybe someone else on this forum does.

Difficult to tell you for sure since we don’t know how much is in your medium right now. Both calcium and magnesium are needed throughout the plants life; but if you have enough in the medium already then you could potentially cut it off 1-2 weeks before harvest. Any idea what the PPM is?

[mrgrowit]

Absolutely. Not sure when the next revision will be though.

Yeah this city is getting more and more crowded. Traffic is nuts and construction is always slowing things down. Oh well

500 scale in the book; I need to specify that in the next version. In general, 500 scale for North America and 700 scale is mostly used in Europe. I totally get what you mean where it can get lost in translation. EC would definitely make it less confusing lol

Yeah it typically shows up on the top, newer growth first and then works its way down the plant.

Great question. I can’t tell you for sure but if you feel toxins are on the plant from this then it’s probably best to not consume.

[mrgrowit]

Coming along pretty good so far. What nutrient line are you using?

[mrgrowit]

Hey thanks for stopping by the forum! Check out pages 76, 78, 94, & 97 of the book for a breakdown of exactly what you’re asking for 🙂

[mrgrowit]

Is that the pH and PPM of the water or nutrient solution going in or the runoff measurement?

[mrgrowit]

Impossible for me to tell you for sure, but out of 13 years of growing, I’ve never had a plant stretch more than 3x. I think we talked about the different factors of stretch in another thread if I remember correctly.

I made a whole review video on it talking about what I like and also what I don’t like. Here’s a link to it: https://www.youtube.com/watch?v=2ORfDg5Tndc

Yeah hard to say for sure. Do you happen to know the flowering time? In general, you should see less stretch for 8-week cultivars vs longer flowering cultivars such as 10, 11, or 12+ week cultivars.

People ask me that question all the time. It is very expensive. I’m not happy with the price, but I am happy with the product.
