Pros: Effective, easy-pour spouts, understandable mixing chart
Cons: Synthetic, cost
Emerald Harvest's 3-part nutrient system is very easy-to-use. The mixing chart on the back of the bottles are easy to match measurements (mL) and most importantly understand. I have not had any issues with plant loc-out while following the schedule exactly. The effect I have noticed is superior plant development as compared to traditional organic gardening; which is no surprise.
The MSDS sheets are easily available for download on Emerald Harvest's website. After reading the MSDS sheets, I will recommend wearing re-useable gloves while handling & mixing. The ingredients contain mostly nitrates with some urea in it which can be an irritant to some, hence the advice to wear gloves.
I have used this system in conjunction with a root probiotic (review to come) and some homemade worm leachate. All together with superior genetics will result in heavy yields and a simple growing season.
This is an on-going review because this product is currently in-use. I will update this post after harvest for a full report on this product's effectiveness into final stages, as well as any issues/alterations that may come up.
Pros: Price, consistency, usability
Cons: Non-sustainable (peat)
General Hydroponics Rapid Rooter Plugs is a great media when it comes to cloning. The substrate is fairly consistent in density, therefore it is consistent in moisture retention. They advertise that the matrix provides an optimal air-to-water ratio, which results in explosive early root growth. I will confirm this to be accurate because 10 out of the 12 cuttings that were placed in the plugs rooted without the aid of a cloning gel.
The only downside to this product is the main ingredient: peat moss. I could not confirm if the manufacturer uses the Canadian Sphagnum Peat Moss Association or another respectable association as their supply. If you know, leave a comment below to further the discussion!
All points considered, this product works and therefore it is a great tool to have on hand for hard to clone plants!
Pros: Non-digital, affordable, responsive knobs
Cons: Weird Noise <video below>
This is a decent little device. It's purpose is to turn on/off a device yet staying in its on/off position for different timing schedules. As you can see from the pictures, the knobs clearly state which is the on and which is the off. It was a simple as plug-n-play which is sometimes required for a good ol' boy like myself. I currently have the timer running in 24 hour mode. A simple combinations of knob twists will unlock photocell mode #KonamiCodeStatus.
The only fault with this product is the spine-contorting, mechanical grinding noise it makes periodically; reminiscent of an NBA clock. This has became an issue only recently and is not a factory feature. I have yet to fully open it up to fix the issue, because its currently detrimental to the plants' survival and I don't know what I'm doing!
**Sorry for the air-pump noise. I tried more times to capture the sound but its spotty like that. #Ideas?
Pros: Mechanical, accurate, labeled switch
Cons: Mechanical vs digital accuracy, price
The Titan Controls Apollo 6 is a standard, one outlet mechanical timer. It's a little fancier than the dual mechanical timer you can get from Harbor Freight (for half the price.) The two differences are accuracy-over-time and the labeled switch.
The cheap dual timer keeps adding time, resulting in my powered device staying on longer than it should. The Apollo 6 has been operating side-by-side with the dual timer, but it keeps time; no resetting needed! Additionally, the labeled switch makes a quick glance turn into piece of mind after I've been fumbling around at the sockets plugging things in/out.
If you have the money, I suggest splurging for this timer.
Pros: Equal air disbursement, tiny bubble size, barbed hose input, cheap
Cons: Feels cheap (bought an extra one as a backup)
AHHHHH! Algae in the tubs. No fear, EcoPlus® 12" Air stone to the rescue.
I knew algae was going to be a problem before starting the tubs thanks to Jeb's videos. I painted the inside of the tub lids, like he recommended, to help block the light but the grow lights are too powerful.
With the algae spreading, I knew I needed to introduce air stones to the Kratky tubs. Using this cheap air pump from Amazon, I left the air stones running for two days straight to break up the algae. Success!! Now the pump runs on a repeat cycle timer (1min ON/10min OFF). No more significant algae buildup and the plants are LOVING the air to their roots.
I snagged these at $3.41 each, if you can find them at this price... buy them up!
