You are impressed with my results but you didnt like my advice so now I'm not experienced? Started outside years ago, the sun makes it easy, and have been inside almost 10 years now. Have fun learning.

Shrink your space. You have 32 ft2 with 1200 watts. 37.5w per ft2. In a 6x4 space it will increase to 50w per ft2.

More light will = more weight, but it gets more expensive to control the heat of 2000w vs 1200w. Bigger fans with more air flow, and A/C is a must if you want to run in the summer. I don't know how much longer I can hold out on upping my game to LED. The nice ones are so damn expensive I just...

Lol, I did didn't I? Sorry about that @dominic9. I started out in soil just like you. I tried to make my area larger and it was a fail. To much wasted space. So I switched to hydro and it helped my yields a bunch. Now I am trying to condense my plants, similar to what you are doing now. My best...

I am currently at a similar stage. I have been running a 12 plant ebb and flow system in a 5x8 area with 2 1000w hps. I have been getting about 4-5 lbs. 1800-2200g. My goal is 6lbs. I am going to adjust things a little and make it 4.5' x 9'. I have 2 different designs drawn up. 18 plants...

One of the best threads you will find on the subject. https://www.rollitup.org/t/understanding-and-calculating-nutrient-ppm.995409/

I used to use it in dirt. Tried it in recirculating ebb n flow. Same results as you. Too much slime.

Works well in soil. Not so well in recirculating hydro. Causes slime. Drain to waste would be ok, but I haven't tried dtw yet.

Once a plant reaches about 6-7th node if you look with a jeweler's loupe you can start to determine sex. Look close and you can see white hairs

Believe the science, Just like the Rona! Lol

Here is more info against flushing. https://support.ilovegrowingmarijuana.com/t/to-flush-or-not-to-flush/6432

I reposted the link. Works now. Explains the Lucas formula but it also explains the 1-1-2 ppm ratio. Remember it's the ppm ratio of npk not what it says on the bag

Just a little info since we got off topic. I contacted Jr Peter's about my question about the order of products, specifically with a cal-mag supplement. This is the reply. " Thanks for reaching out and for your choosing Jack's! Mason passed along your...

I run 2- 8" xxxl hoods 1k each on a 4x8 footprint. Minimum distance 18"-24". With 8" vortex 739 cfm fan. Works fine as long as I don't overfeed.

Here is the 1st reply. "Plant Amp is a great source of organically derived calcium that can be used both as a foliar and watered into the medium. Unfortunately proprietary means just that... I can’t divulge proprietary information about the formula." PPM values are pretty vague as well. "Below...
