LED Light Intensities
Recommended LED PPF/PAR Values / DLI Based on 20 hrs of light.
Seedlings 150 - 200 umoles / DLI 10.80 - 14.4 moles per day
Veg up to 9" 450 umoles / DLI 32.40 moles per day
Early bloom 500 umoles / DLI 36.00 moles per day
Mid bloom 650 umoles / DLI 46.80 moles per day
Late bloom 750 umoles / DLI 54.00 moles per day
Ripen 400 umoles / DLI 28.80 moles per day
*** Use extreme caution going 700 umoles or higher @ 20 hrs/day this could cause leaf burn***
PPF measures the total amount of PAR emitted from the lighting system per second.
PAR is the amount of light in the 400 - 700 nm color spectrum that can actually be used by the plant.
PAR does not measure the amount of UV and Infrared that plays a part in trichome formation and cell quality.
DLI is the total amount of PAR the plant has received per day
Our goal is to have a minimum DLI in the 38-40 mole range when it bloom.

Having your plants in the optimum LVPD (Leaf Vapor Pressure Deficit) ranges helps them absorb Co2 to properly conduct photosynthesis and allows the root system to adequately utilize water and nutrients. Using average leaf temperature is the best way to calculate LVPD. Measure this temperature using an infrared thermometer.
LED lights tend to have leaf temperatures lower than atmospheric temperatures in the grow room. Growers using HID, Fluorescent bulbs typically will have temperatures higher than room temperature. With HPS leaf temperature can be 8 - 10 F higher than room temperatures due to the amount of infrared emitted by the bulb.
Recommended LVPD
Seedlings/Early Veg 0.4 - 0.8 kPa
Late Veg/Early Bloom 0.8 - 1.2 kPa
Mid/Late Bloom 1.2 - 1.6 kPa
*** Danger Zone*** Below 0.4 kPa / Over 1.6 kPa

I'm using a blended soil mixture of 65% Ocean Forest, 30% Canna coco coir with 5% extra perlite to grow my auto flowers. Wanted some opinions on when most growers decide to start feeding. Like Day10, 14 or 21 etc. ?
It seems like everyone starts counting their seedlings day 1 differently. Is the true 1st day for a seedling when the seed breaks the surface of the soil or when the first true leaves emerge from the cotyledon?
Hey man, good question and I think it just comes down to personal preference. I include the germination progress on my diary as I believe it's also important. I count day 1 when I see the seed pop out the soil that for me is day 1.
Hi there!
There are couple different seaweeds used but Ascophyllum Nodosum is the one I'm using too and it is good.
Basically they should all be the same but only the potency is different.
For example I have only 6% dry matter in it but Top Crop Big one is 24% so 4 x more concentrated
Week 3 Update
Just using Bio Rhizotonic about every 3 to 4 days minimal watering not to the point of run off yet. I see a few roots starting to poke out the bottom.
Started LST work as soon as they were tall enough. I've been holding off on starting LST too soon and bending them over 4 to 6 inches above the root crown then arrange the rest for best position then pull back any large fan leaves to allow more light to the bud sites. They started stretching and first pistils appeared around day 17.
Lowered my light a few inches and dropped my humidity to increase plant transpiration which should induce heavier feeding in my opinion.
Week 4 Update
They are stretching showing off some nice pre-flowers.
Performed some leaf tucking and moved branches to their final positions.
Gave them them some light nutes end of the week to the point of slight run off.
Lights are at about 18 inches, dropped humidity to around 55%
Week 5 Update
Girls are officially in bloom. Started with bloom nutes this week.
Dealing with a low runoff ph of like 5.2 ph not good. I top dressed the pots with 4 Table spoons of pelletized lime it's pretty slow acting. Looks like Fox Farm strikes again they see to be very inconsistent with soil ph from batch to batch.
Week 6 Update
Once again lazy week for photos. Buds are starting to fill in nicely. Increasing my feeding solution ph with Armor Si to 6.8 along with top dressing my pot with pelletized lime has increased my run off ph to 5.7 to 5.8. I was able to feed about every 3 to 4 days. I usually let them dry out a bit more between waterings/feedings since I'm a self admittedly heavy handed when it comes to watering. They are looking a bit hungry, plan to increase their nutes week 7 to start bulking them up.
Week 7 Update
Buds are filling in nicely. I'm feeding/watering about every third day letting them dry out well. I'm probably pushing them a bit hard in each direction feeding-watering -drying out to induce a bit of stress. Push them to their limits. Runoff ph is running around 6.1 which is much better than it was the previous weeks. Some leaves are showing some light stress/burn but are holding up well. Struggling with the summer heat to keep temperatures under 82 F while in bloom.
Week 8 Update
Buds are starting to bulk up nicely. Trichomes are becoming cloudy no ambers yet. They looked a bit hungry so I kicked up they nutes a bit. They are getting close showing some fade in coloration but are stacking on some weight still. Each phenotype seems to be feeding differently. They get what I give them and they will like it! I started using using a diluted LABS(Lactic Acid Bacteria Serum) and Blackstrap Molasses lightly drizzled on the surface of the pots after the feeding in week 7 and 8. Going to try to get in a couple of more feedings in before the big flush. Still using wet then dry drought stress to push then to their limits.
Week 9 Update
I started flushing this week after seeing some amber trichomes showing up. Leaf color change was very rapid fastest I've seen. They're all throwing our some nice colors.👍
