What PPM to use for solution

18 years ago

Hi everyone. I am new to this forum and have now been growing lots of different plants via hydroponics. My garden is indoors, and I have two 1000 watt (1 Sodium, 1 MH) lights, three high volume air fans, and lots of buckets of plants growing at the same time.

I really struggled at first to learn all the basics like PH, PPM, air flow, how often to change out solution etc.

All my plants are growing in a bubble bath. I have grown Corn, Cucumber, Yellow Neck Squash, Zuccinni, Roses, African Violets, All types of peppers hot and sweet, and a pepper corn plant, peanut plant, onions, lettuce, well almost everything.

My question is in regards to pepper plants, and what I have read researching the net. For the most part I see a PPM of 500-1500 for hot pepper plants. I saw a post where one guy grew mature, heavy fruiting peppers in 500 ppm solution.

Can someone who grows peppers hydroponically and been at it a few years tell me the best PPM from cradle to grave for a Hot Pepper plant?

Cradle-to-grave 450-550 ppm in aeroponics.

Constant NPK ratio.

mhargraves,

Do you run the MH and HPS lights at the same time? How many hours per day?

I do run both at the same time in a room that is about 20' x 20'. I started with one 400 watt MH. Later on I went to buy another one, and the place I bought it from suggested trying the Sodium bulb on the fruiting plants.

So for about three weeks I ran the 400 MH, and the 1000 HPS lights. Then I wanted a backup system in case one of the lights went out and bought another 1Kw MH lamp.

Now I run both lights at the same time. I have the seedlings, cuttings, and early plants under the MH, and the full bloom fruiting under the HPS lamp.

I run both lights from 6:30 am to 10:30 pm every day on a timer along with the fans. The temp runs from 70 to 85 F.

I'm impressed! Been probably 15 years since did hydro and am thinking abt starting again.

What surprised me the most was how nutrients affected taste. We hear all the time abt how grapes grown in a specific region make the best wine & how peppers grown in a certain region are more flavorful and perhaps hotter etc. I'm now a believer.

Looking forward to your updates!
