Okay Trekkies, If I want the plant energy headed to nodes in the heavily lit area of the upper canopy, I'll prune the small shoots on the branches, at flower day 14, and, I will leave on the fan leaf from the snipped node. I don't want to make a lollipop, as my canopy is kinda bowl shaped...

Tht's all I wanna say about that... except GO WATCH IT !

Make a 5 gallon CO2 machine of yeast/sugar, except make a lot of output lines. Attach each output line to the largest fan leaves, using a twist tie, and then put each leaf inside a small plastic baggie (this serves to keep the CO2 within the leaf surface). Does anyone know if the baggie would...

Say : I want to keep my favorite strain but I don't want to make my whole garden seeded, and I am pressed for time... Go check my thread for the answer: https://www.rollitup.org/indoor-growing/81761-males-garden-without-pollenating-all.html

Say you have a garden, and you're ready to flower, watching patiently for the sex to appear. You ultimately want a crop of sensimilla seedless buds, but oh no, then, you see a few males... Do you chop the boys down? No, YU WANT the potent kind bud's genepool to stay alive because there aren't...

According to a university paper at http://www.energy.wsu.edu/documents/building/iaq/CO2inbuildings.pdf we exhale 35,000 - 50,000 ppm CO2. That's an insane amount of CO2!! So I say, USE IT !! Just tape together a bunch of garbage bags and sit for a few hours exhaling into them to fill them up...

Anyone estimate the weight I could expect from a vertical scrog with 2 400 watt CHMs in a 4'x4' area?? HEAT and stealth are a major concern, which is why we want to try CMH... Is the bud *that much* worse than HPS that I'd want to avoid CMH?

found a sweet research article at: Acta Horticulturae This paper describes the effect of alternating magnetic fields on plant germination and growth. Experiments were conducted utilizing various frequencies and two states of polarity. Electromagnetic coils were used to generate the fields and...

It would be nice to supplement indoor plants with natural sunlight, to fulfill the full spectrum for photosynthesis. How would it be possible without using fiber optics to bring the sun's full spectrum inside your house from varying angles... Can't we just bounce the light from A to B to C to D...

In the book entitled "Growing Crops and Plants by Electricity" at: http://ia331313.us.archive.org/2/items/growingcropsplan00dudgrich/growingcropsplan00dudgrich.pdf The book's author performed an experiment using Mercury lights during germination to make them crack open faster. (See page 29)...

Anyone ever tried an experiment like in this free pdf book: Internet Archive: Details: Growing crops & plants by electricity. Explaining what has been done on a practical scale I added a negative ion gen. to a garden that was dying, and the next day there was a lot of new growth...
