I guess I'm just confused by the '2mls/L' dosage. Aqua Flakes is their recirculating hydro food. Here is their feeding chart (https://www.house-garden.us/wp-content/uploads/2017/10/10-6-17_8-week-feeding-chart.jpg).

It's not just 20L, it's 20L of A+B so 40L total. They're saying on their site that 40L only makes 587 gallons which is a dose of 68.1 ml/gal. And then $219.95/587gal = 37 cents

I *think* they're going off of feeding charts? I just crunched the numbers for Maxicrop. They claim that 16 lbs (7257.48g) makes 1614 gallons which equals 4.5g/gal. According to maxicrop's feeding chart (https://gh.growgh.com/docs/Feedcharts/GH_Maxi-REC_03216am.pdf), 1.5tsp/gal is recommended...

In hydro 1.0 EC is pretty safe. The N is mostly nitrate so I'm personally not worried about tip burn in my setup. If I were in containers I'd be feeding at about half that, maybe 0.6 EC with my 600w lamps? I'm not sure why they're adding more calcium and magnesium as it looks like my bag has...

I started putting mine in a tupperware container too. It's still dusty but it's much better than messing with a bag.

How does the new formula differ from the one I'm using? Got a link?

I definitely agree when it comes to hydro. In peat/coco/dirt, a veg formula from start-to-finish absolutely crushes it. The mineral uptake seems to be different in containers, maybe because hydroponics makes said minerals more accessible? Maybe it's because ebb-n-flow hydro plants get flooded...

Day 15 today... So things are moving along as expected. In terms of the overall health of the plants, they're perfect. The structure however is my only critique and that leads me into what I wanted to talk about today: NPK content of Mega Crop. Mega Crop supplies a NPK of 9-6-17 and that is...

So aside from the horrid math with the Aqua Flakes cost comparison, MC *may* be getting some of their numbers from the manufacturer's recommended dose? MC is one of the least expensive foods on the market but their worst offense is over-stating how much cheaper they are. For the average...

So it looks like Mega Crop did not take down the cost comparison that I saw on their site. It can be found here (https://greenleafnutrients.com/product/mega-crop/?v=7516fd43adaa#!/NPK). So what rubs me the wrong way is that they are comparing their own cost of use at 4.1g servings which equals...

And there's your inferiority complex again.

Dude, you're growing thumb-sized buds in a closet and are conducting 'what if I grew plants higher than the light' tests. Is that even a test? lol Here's a test idea: what would happen if you actually pruned your plants correctly as to maximize the yields of your 100w LED. Start a journal...

Look at you finally quoting posts correctly! :clap:

But if I move along, how will you ever figure out how to quote a post correctly? lol

Dude, you're trying way too hard.

Day 8 With DynaGro below. As you can see the MC plants had a bit of a size advantage going into this comparison but given the footprint of my light that doesn't really affect the yield as much as you'd think.

Day 8 today As I previously mentioned I’ll be doing weekly res changes. The pH of the res here at the end of week one was 6.22 which isn’t terrible at all. The freshly mixed up food at a feeding level of 1.1 EC landed the pH at 6.44 so for whatever reason I needed to make a pH-adjustment this...

The short answer is no. I think that the reservoir and the table should match so with that being said, a 60 gallon res flooding a 2' x 3' (roughly) table with just six plants is overkill, IMO. If that were my setup, obviously that would be plenty of water to last a number of weeks but I...

Weekly res changes. I top off once after 4 days. By adding water and some plant food. Weekly res changes.
