    mix LEDs with different power requirements on the same driver?

    I'd like to add some 660nm and 730nm diodes to my DIY 4000K strip light to give my plants a boost from the Emerson Effect, and it would be most convenient to put the diodes in series on the same driver, but the 660 diodes require 2.4-2.6V at 350ma, the 730 are 3.2-3.6V at 350ma. As long as the...

    Reveg or start over from cuttings

    I had 2 plants in hydro, 6 weeks into 12/12, and made the decision to chop them both due to a number of factors. I need to start again, either from cuttings taken from earlier clones of the same plants, or reveg the existing 2 plants. The idea of revegging to take advantage of fully developed...

    Supplimenting with 660 nm

    I'm considering adding 20W of 660nm and 6W of 730nm to my ~400W, 4000'K Bridgelux strip DIY on separate drivers for Emerson Effect during lights on, and 10 min of the far red after lights out for Flower Initiation. Questions for those in the know: 1) Is this even worthwhile? Can I expect a...

    Hydro system maintenance

    As I'm going through the process of cleaning my hydro system after summer downtime by pumping a dose of pool shock through my reservoir, plumbing and chiller, and doing a bit of scrubbing of whatever surfaces I can touch, I'm wondering what else I should be doing. What do the rest of you hydro...

    HLG 600-R over a Panama and a Diet Durban

    My new 600-R arrived last evening: and after getting it unboxed, inventoried and clipped together, it replaces the 200-400W Bridgelux 4000K DIY I've been using for the past 3+ years. After getting it hung, plugged it in and dialed up to about 1/3 power at 233W output, the top of the light and...

    feminized pollen from autos

    What schedule or indicator is used to start spraying STS or CS on auto females to coax them into producing pollen? Start spraying buds at week 5? First sign of apical buds? What has been reliable?

    Adding Emerson Effect to a strip light

    I'm wanting to leverage the Emerson Effect -- primarily to shorten flowering, but I wouldn't turn down increased yield as well. Perhaps it's my age-addled brain, but synthesizing all of the various processes and parts into the "right" solution leaves me with a lot confusion and questions. If I...

    Competent grow room electrical advice needed

    Looking for some best-practices electrical advice. I've been doodling with Mycodo on a Raspberry Pi for data collection and monitoring, but would like to transition to using the Pi to control some of the high power devices in the grow room; e.g. lights, heater, chiller, etc. My grow room is 6' x...

    STS and naked anthers

    Sprayed this female with the standard STS recipe at the beginning of 12/12, and again a week later. 3 weeks later, this is what developed: The buds are covered with anthers, very short/no filaments, and no sepals. These anthers did produce pollen after another 2 weeks, but nothing compared...

    Recovery from unintended flowering...

    Two Durban Poisons that I'd started from seed in an 18/6 indoor environment since April 1 were put into the ground outdoors on May 2 with day length of 14+ hrs. One of the plants took off after a week and is doing great. The other decided to stretch out and to go into flower. I thought...

    Cannabis 420 Store?

    Any info on these folks? Prices are stupid low, but looks like they do their own breeding and shipping is a flat $25, and a $175 minuimum order. https://cannabis420store.com/ The unknown seed source, seed selection, and low price is reminiscent of the Aurora Winds Botanical scammers. Be nice...

    Hydro Newb looking for help with DIY build

    Okay Hydrophiliacs, after a couple of successful soil grows – first with Jack's Classic, then with organics only – I find myself wanting to give hydro a try. I'm a dedicated, frugal DIYer, so buying a pre-fab setup is not part of the equation. I'm looking for advice on putting together a 3-4...

    Slow growth -- repot?

    My first 2 grows went pretty well. 8 oz and 10 oz respectively on a 2x4 scrog. Now on my 3rd grow and not off to a good start. As before, I started 2 beans – 1 Jorge's Diamonds and 1 White Widow -- in peat filled cups. They broke ground after 2 days, then after 1.5 weeks they were transplanted...
