Hey everyone!

After growing for 2 years im giving up on promix and trying coco.

Setup:

12, 1150w de hps
11 ton ac
200pints deh

60ft x 4ft wide table that sits 1ft high on concrete.

Distance between bulbs is 5ft.

Im confused / unsure what setup will give me best yield + flower quality. Veg room/time not an issue.

Option 1 - 23 plants that will be vegged to 4ft, topped once in very early veg. 1 plant per light + 1 plant between light. 6 gal pots.

Option 2 - 48 plants, 4 per light, flipped at 36 inches. 3gal pots. Topped once.

Option 3 - 108 plants, 9 per light, flipped at 18inches. Not sure if need to top.

Mother earth 70/30 coco perlite mix. Auto drip irrigation. Multiple feeds per day.

Thank you!!

Yield depends on skill. I like option 3 veg 40 days top twice in 3 gal pots.

If plant count is not a concern go option 3. Can I ask why you're giving up on promix?
After about 8 cycles trying 3 and 6 gals, diff veg times, plant counts, ppfd, enviro, i cant seem to break 1.25pounds per light.

The most i get is 4 oz per 6gal, 5 plants per light. Vegged to about 36inches finished 48inches.

I went through at least 10 strains.

My last run was in 3 gals, 8 plants under a light and got just over 2oz per plant. I could fit 9th… but that would still give me under 1.25#.

Im thinking frequent irrigation and oxygen benefits should give me plants with a lot bigger buds?

Um. I'm just going to say. You're obviously not that much of a newbie. Course, I'm small scale.

But. I grow 'hempy' hydro and they grow grow grow.

I consider myself a newb until i hit 2# per light lol. I hear ppl doing 3 and 4# per light so my current 1.25 is like kindergarden.

Well sir, that makes me a total n00b compared to you. My yields pale in comparison, mainly because of space.

Best you will do with hps is about 1g/w (2.5lb per light abosulte max) pro mix allown will not get you there, will have to feed liquid K to get your buds to swell more befor they finish

Thanks thats my goal, just 2# per light which would be like .9/w. Youre saying I cant hit that number without pgrs?

You are going to by wowed by how fast and big plants grow in coco. I just made the switch myself and I am floored by results. I don't know what my end results will be yet, but pretty sure they will be great!!

All i know is the grows i was trained on were under hps bulbs in 3 cycles our worst yeild was .75/w and out best was 1.1/w. 7 gal pots of happy frog mix with perlite, salt feeds pushed to 1300ecm.(think it was cutting edge but after 13 years im not sure)
Of course gentics play a big role we were running strawberry cough

I use 75% coco, 25% perlite in 3 gal with auto feed 3 times a day. I am nowhere near your space and plant count.

I scrog 2 plants (veg 40-50 days) each plant is under 2ftx2.5ft nets with 580W LED.

Last 3 grows: average 10oz/per plant (best was 11oz). I have maxed yield output.

There is a guy on i c m ag

It's a setup u might like.

Thanks for this. A couple of questions if you don't mind:

- do yo know what your ppfd is at the canopy?
- do you use co2?
