Looks great! man. Thanks for the ride.

Only hope I can grow like that someday soon.

I'd grow with T5's myself but I'm concerned about temperatures. Its damn cold in my basement. I'd be worried about it not getting hot enough in my space. It's currently running about 75 with my 400w HPS.

Thanks again. Not sure if you're still subbed into mine still, planning on chopping down at week's end. Not nearly as successful as you've been. Turned my inline fan off and burnt one of my plants.

I'm still subbed and following, just keeping a low profile as you've got a lot of big hitters on your thread.

Lookin forward to your harvest, thank you for stopping in!

In Review

This grow was defined by a few major principals, each of which was experimental to my experience. The new growing situation, its experimental lighting, and the implementation of 99.9% organic gardening techniques are the three components that will be addressed in this review.

The tent measures 1.5'x2.5'x3' wlh from Gotham Hydroponics; it proved to be an effective microgrowing space and it fits in the surrounding closet with just enough room to run ventilation ducts. The two “exhaust” ventilation holes in the tent come with velcro covers and pull-tie seals; they’re on the sides of the tent and could be more useful in the evacuation of heat if placed on the top. There are large passive intakes on the lower bottoms of the left, right, and rear walls that are covered with a screen mesh as well as a “lightproof” flap. There are also small intake-fan/electrical holes at the bottom corners of the back wall. Given Florescent lighting and space requirements: 5/5 rating.

The ventilation system was an all-DIY project and though effective, was too expensive as there was no definite plan. The original idea was to use a single 4” booster fan to exhaust the cab while pulling air through the passive intakes. It was effective through veg at keeping the temperatures stable at 78F. This changed when flowering began and a carbon filter was required. The DIY filter was more duct-tape than carbon and it provided substantial resistance on the air stream. The 4” fan was not strong enough to push air through the filter and temperatures were in the upper 80s. In need of a quick fix, a 120mm fan and 80mm fan were purchased. The 80mm was installed as the intake in one of the 3” holes (fit surprisingly well) and the 120mm was added to the beginning of the exhaust line. This was enough to keep the temperatures less than 84F with the lights on. Due to the lack of pushing power, however, this ventilation setup could not fully remove the plant’s smell. With the closet door closed, it only smelled faintly of herb before lights on. When open, at least 1/2 of the apt smelled of burning bud and electricity consumption. After further research, a centrifugal fan would have been most effective. Final notes about ventilation: 80-84F, 45-60% RH, and minimal smell throughout flowering, expensive. Ventilation rating: 3/5.

The use of PAR T5 lighting was a pleasing and effective method to maximize the return on investment in this small space. During the planning stages, the tent was intended to be a seedling/clone; a 2 foot 4 bulb T5 fixture with 6,500k bulbs was purchased under this assumption. When the plan changed, a decision had to be made: get a small HPS, switch to CFLs, purchase 3,000k T5 bulbs, or a combination plan. Out of the actinic, I stumbled on the pr0fesseur’s thread. He offered a way to maximize ROI using the T5 fixture through the implementation of aquarium bulbs. A combination of 50/50 red/blue was recommended for a 4 bulb fixture. 2x Fiji Purple, 1x UVL Red Sun, 1x UVL 454 were purchased and installed from ReefGeek. This combination was very successful. It produced healthy, green growth with compact internodes while using only 96w of electricity with little extraneous heat. During flowering, the buds developed quickly and started packing on the trichs. At the time of purchase, the Fiji Purple was believed to be 50/50 red/blue; however, I believe that it is dominant in the blue spectrum and until this can be confirmed or denied from multiple sources, it should not be the “base” bulb. Please note that this bulb is unique in its output and similar results with different “purple” bulbs are yet to be shown. If a four bulb fixture is used, this could be better employed as a filler bulb in a red dominant combination: RedSun, Coral Wave, Fiji, RedSun; Fiji, RedSun, Fiji, RedSun; or RedSun, 454, Fiji, RedSun - for example. Given the space, heat, and resin production: 5/5 rating (with room for improvement).

The most familiar part of this grow was the organic gardening principals. These were reinforced by the mid-grow reading of Teaming With Microbes. The soil consisted of the following: 2 CropCircles Coco discs, 1 Gallon Sunshine Advanced #4 mix, 1 Gallon Vermiculite, 1 Gallon Hydroton Clay Pebbles, 2 Cups Espoma PlantTone. MycoGrow was added to the rootball at the end of veg and would have been most effective from the start. Compost was added to the top of the soil three weeks into flowering, this allowed enough biological activity and nutrition through flowering. The plant experienced burning through the excessive application of Guano tea. This burn caused the plant to produce leaves later into flowering than preferred and could have been avoided if the teas had been limited to EWC and Molasses. The improper application of 5/5 principals gets a 2/5 rating.


Summary
This grow was a wonderful learning experience with pleasing results. After four days of drying, the bud has been jarred with a grassy smell. Over the course of the curing period, the spicy-sweet pine smell is likely to return. It smokes smooth, expands in the lungs, and stays lit for an entire bowl; the effect is mentally relaxing with the addition of physical couchlock upon higher dosing. The bud is comprised of more resin than calyx material and when combined with the 25g pre-cure weight, it reinforces my belief that the burn had more of an effect than I originally thought. Overall, it’s high quality medication from a pleasing experience with definite room for improvement.

Rating of the outcome: 3/5
Rating of experience: 5/5

Thank you for reading, I greatly appreciate everyone’s contributions and encouragement.

This experience has proved to be a wealth of knowledge about gardening and myself. And although it was far from perfect, I would consider it an honor to be posted in your journal.

Thank you for the kind words and most of all, the inspiration.

You have made great grow! Good job mate! I will come here and give you rep when I'll be able to. Remember I was here from the second post and this was worth following! Well done sir!

I do remember, thank you maariic.

You're welcome at the new grow too!

oTm, you asked about fungus gnat control. One of the more creative tactics I've read about is the use of cinnamon ... it apparently knocks'em way back. But since you've added worms to the mix I don't think cinnamon would be such a good idea. There are nematodes that are used to control the gnats, and I'm guessing they'll leave the worms in peace. Can you source the right nematodes? cn
? How much cinnamon would i b mixing per gallon. so i could scare away these gnats. Thx

I've never had to do it myself, so basically "I don't know" ... but it wasn't mixed into liquid. It was used as a sprinkle/topdressing for the soil. A tablespoon for a 5-gal pot? cn

Neem Seed Meal or Diatomaceous Earth would be more effective. 1TBS/Gallon would work fine.
I spread a good amount of DE as a cap on the top soil, but the little bastards kept on coming. I don't 'do' soil, but was baby sitting a plant in a pot for 30 days. It was brutal. When DE failed, I resorted to an electric fly zapper 4-5Xs a day. I would have loved to try cinnamon, but I pulled the plant 4 days ago

Cinnamon destroys microbiology, think of it as a flamethrower in a jungle of VC fungus gnats. Prevention is the only real cure.

NOPest Strips work but Dichlorvos is a carcinogen.
