NICE!!! It looks pretty hight~
NICE!!! It looks pretty hight~
Outdoor plants all in early flowering. Average height 5'+ & still growing. I germinated seeds 2 wks. later than usual to control height & size, but didn't make a difference.
From L to R, Lost Coast OG, Cheesedog, & Jamaican OG.
818 Headband on L, a smaller Cheesedog on R.
Soil Mix
I buy commercial bags of soil & add ingredients to it. One that I use regularly is Royal Gold Mendo Mix. Each yr. I try a couple of new ones. The new ones this year are Santuary's Empire Builder, Dr. Earth's Motherland Mix, & E.B. Stone's Recipe 420. Outdoors I find peat based soils are best, some peat/coco blends are fine, pure coco mixes are least preferred. The Recipe 420 was a free sample from E.B. Stone rep. Tried it with a new strain & a familiar strain. I can tell this soil is a keeper except it's mostly sold at regular nurseries who jack up prices & seldom discount.
I add most/all of the following to the bagged mixes:
Dolomite lime
Gypsum
Soft Rock Phosphate
Bone Meal
Greensand
Azomite
Sul Po Mag (langbeinite)
Alfalfa meal
Cottonseed meal
Feather meal
Mycorrhizae
Azos (N fixing bacteria)
Bat guano
Worm castings
Perlite
Kelp meal
Other optional ingredients:
Manteca River Loam (rich native soil from Central Valley)
EB Stone Bulb Food
EB Stone Sure Start
EB Stone Ultra Bloom
Humic Acid (solid form)
Insect Frass
Water
I use tap water, but through a hose end charcoal filter. Additionally, I add drops of dechlorinating liquid to further remove chloramines. Tap is ~pH 7.6, fairly hard.
pH
I rarely test pH. In this outdoor grow I first tested pH when plants were entering transition stage. A couple showed early N depletion at plant bottoms so I wanted to check to see if pH was within acceptable range. A major 10 day heat wave had me watering every day so I wondered if daily hard water might drive up pH? A couple were a little high...nearly 7. Most were ok at usual 6.6-6.8 range. Since it was time for a good N hit for all plants, I used cottonseed meal, a slow release N source that also reduces pH. Rechecked today w/ good results as all were lower, between 6.5 to 6.8.
I can understand the greater importance of pH in hydro or even soils when using synthetics, but still chuckle a little when I see so much well intended advice to check pH when a leaf is this or that. To each his/her own but I believe healthy plants can be grown without ongoing pH checking or fussing.
NLxBB auto
So so looking bud, not beautiful, not ugly. 12+ grams. Creeper mellow indica effect. Decent. Would like it more if it wasn't harvested on heels of recent indoor plants, which were better looking & much stronger. Still fun to grow my 1st. auto.
