Hot Pepper Plants and Sunlight

rebel_renegade1May 23, 2010

I had a similiar question about Pepper Plants...I.E. Jalapeno, Habanero, and Cayenne. I live in a house that has ample shade by the many trees in the yard. I planted my Garden closer to the house so I could keep it up better. Well, The Spot I planted it in gets spotty sunlight until Between 11 and 1 O.clock or so, Then it does get full sunlight. It might be more or Less. I can't be completely accurate. The spot gets sunlight but it is often spotty. Does anyone know if this will be an ok amount of Sunlight? If not is there a way that I can get them to grow better and bigger even without an ample supply of sunlight? I have soil conditioner mixed in with the soil and Fertilizer spread over the garden and do water it, but I wanna make sure that the garden grows good. Any tips or suggestions would muchly be appreciated!

Five hours of direct sunlight will provide about 33 mols per day, peppers need 22 mols/day to thrive.

A measurement of the accumulation of PAR light in a 24-hour period!

For sunlight:
Lux (from a light meter - bright sunlight in the middle of summer is about 110,000 lux) divided by 10.76 x .000718 x hours per day.
Footcandles x .000718 x hours per day.

Interesting, it's always been my experience that even one mole kills plants :)

juicyj(Zone 6) head hurts. should be long as theyre getting about 6 hours of (mostly) direct sun a day they will be good....though for future reference the more the better....idealy you would want them to get about 10-12 hours a day....if possible.
the more the better....but either way i would wager theyll be fine.

Wordwiz, that's fascinating! Where could I look up the number of mols needed for other plants? Do you have a reference somewhere?

I have an EXTREMELY sun-challenged garden situation, with three separate spots that get, respectively, around 2, 4, and 5-6 hours of sun per day. It sucks, but that's what I have to work with, and I do make it work, with about 45 total pepper plants.

The upshot of it is, 5-6 hours is enough to get you a full load of full-sized peppers on a plant. 4 hours of sun per day will get you a decent but not completely full load of peppers. For instance, a Thai Hot that might produce 35-50 pods in optimal conditions might give you 20 or maaaaybe 25 with 4 hrs of sun. 2 hours will get some plants to produce fairly well while most will give you a couple of pods and not be worth the effort. For instance a jalapeno early that might produce upwards of 35 pods in ideal conditions might give you 5-8 pods in 2 hrs of light, or less. Or a Serrano that might produce 25 may give you 3 or 4 with 2 hrs of sun. You really need a minimum of 4 hours of direct sun to have an enjoyable growing experience, and 5 or 6 hours should be the target.

Hope that helps.

This site discusses Daily Light Integral and lists bunches of different types of plants and how much sun they need. This one has the formula for calculating the DLI.

Thanks wordwiz. This sort of stuff intrigues me. I'm off to take a look so my head can hurt too!
