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

WEEK 1 UPDATE
Trying out Rocbud for the first time very impressed with the ease and speed of receiving my order very professional. Received some nice samples of Si 28 and P 31 Microbes along with a few extra seeds with the order ππ for Rocbud.
Picture perfect start all seeds popped and sprouted quickly. All four are showing nice fast even signs of strong growth. Dropped my light down to 24 inches on day 6. Expect to see some nice growth for week 2. My daytime temps are running about 80 F with 73 F nighttime temps. The temps listed above are not correct even after changing it and saving it keeps going back to 50 F. GD fix this issue please.
@Philindicus, I feel that's a solid judgment call. You got me thinking about it yesterday and I read up on calcium toxicity side of things and the related consequences. I believe you're correct. That's not "copper spotting" that's burn.
Learned from this. Cheers man and good luck knocking down the Calπ. No P deficiency yet? Probably goodπ
@Grey_Wolf, @JinksyGrows,So after doing a bit of research I've come to the conclusion my magnesium deficiency is definately being caused by a excess of calcium. So something is out of wack. We all seem obsessed over deficiencies that excess nutrients causing issues is often overlooked. π
@Philindicus, love it! thanks for the details - great info to digest. I'm using 20L airpots for the first time... same fall :) I have yet to see the root system and assess once I harvest - thankfully no gnats, just springtales probably from watering the coco at lights off :) . I fertigate once daily now at lights on and that seems to work very well with the coco still slightly damp at the next watering. I liked the idea of the airpots simply for the increased aeration. Really good points on the roots growth and behaviour of cannabis plants. And thanks for sharing your approach - I need a few more grows under my belt to get to know my roots :) .
@HazeyBobby, I'm using 3 gallon maxipots with 1020 reinforced seedling trays to catch any runoff. I just use a small wet vacuum to remove any excess runoff. 2 pots fit into each one. 8 pots fit nicely in a 2ft by4ft guerilla shorty tent. I love the pots they are fairly deep over 11 inches. It seems when running autos when the roots hit the bottom of the pots it triggers bloom in my opinion. After using air pots and getting hammered with fungus gnats from every angle I've found using mosquito bits BTI in the bottom of the maxi pot and adding some to the top of the soil I've pretty much eliminated the issue. I fell for the airpot fad. Personally feel it all a bunch of hype. Essentially air pots air prune the root tips which is fine for trees/plants which tend to have larger fiberous root system. Pruning fiberous roots force them to grow the finer feeding type roots. This root pruning is not needed for cannabis to grow feeder roots. I feel air pruning is creating unessesary stress on the root system.I premoisten my soil mixture before I put it into the pots rather than adding a dry mixture then over sturating the pot with water until the root system is large enough to use the water. Moistening the soil firstalso gives your microbe herd a head start breaking down the nutrients making it easier for your root system to absorb them. If you have a good soil/ coco mixture theres plenty of oxygen reaching the root system. In my case I typically have roots coming out of the bottom of the pots during week 3. End of week 4 is the first time I will water to slight run off to see what ppms I'm dealing with. Week 5 if they are too high they will get a small flush to get the runoff under 900 ppm using 0.50 ppm scale. Then I add my nutrients to the last 1/2 hallon of flush water. Then I start a wet then dry watering/ feeding schedule checking my runoff ppm and ph weekly. This system seems to work well for me based on my watering style/ habits.During bloom I typically can get 3 feeding/ waterings in a week until the plants start slowing down during the late bloom phase. Last 2 weeks during flush/ripening I use some drought stress to trigger the plants natural instincts to increase resin and terpene production.
Hot damn. Magazine quality buds Phil. Fantastic work and photos. Kinda feel like I can taste the pictures, haha!
Great success, great bud. Enjoyππ
@SirDillton, Most of my grows tend to dish out 1.5 to 2 oz per plant of quality bud fairly consistently using soil and 3 gallon pots. I think they have the potential to grow fairly large if grown in 5 gallon pots of coco coir which would definately increase harvest amounts. They handled the stress I put them through quite well and still produced some very fine buds.
@SirDillton, Yes, I'm may be able to start harvesting at least one maybe two next week just waiting to see some more amber trichomes to show themselves.π
LAB! ππͺπͺπͺ. And on a diesel strain too! Crazy dank smell man.
For me, I dare use it only on the last two weeks. (Unless I already am feeding it to my other grow).
@HazeyBobby, yes it is. I try to match different strains by harvest times in weeks but it's difficult to match growing conditions to others diaries. Using two lights gives me a bit of flexibility. Height is more of an issue for me. I'm beginning to think I may try FIM or topping with some of the larger strains at some point. I'm still trying a bunch of strains to see which ones are to my liking. Then I'm going to go back and do a 2nd round with each strain.
killing it as always Phil! Looks good, sucks about the bug but at least ya got him early!
The amount of growth you have from day 7-14 itβs absolutely Insane. π€―
@SirDillton, They are doing alright. I think my soil mix is too hot this time around because I have some nutrient burn on the leaf tips starting. Gave them a flush they were over 1800 ppm. Took them down to under 1000ppm. The next couple of weeks I will see how good or bad it was.
Nice! Ya Grow Diaries has some issues. All my diaries I recently started wont save mine either I enter 78 and 70 both ends up on 50. Hey is that one in center going to be a solo cup grow?
Some lovely looking ladies. Been hearing alot of good things about @rocbudinc lately. Think they'll be the next genetics I grab. Anyways Fantastic work. Keep doing what your doing and may the ganja garden gods bless you with good fortunes the rest of the way.
Holy smokes, 21 days and they're already so big! I see why you're semi-concerned about the stretch. If you go for 24/0 I hope it works outπ. If it doesn't, no worries! Back to 18/6.
Cheers man and continued luck with these fast buggers, this week.
