Heat! (I'm Too Hot to Keep My Leaves)

An increase in heat to high levels or a sudden "shock" of a severely hot day can trigger leaf yellowing and drop.  Many times the leaves will drop very quickly with only slight yellowing.

This "yellowing of leaves" is a simple survival reaction by the plant that allows it to conserve moisture.  Wilting and scorching can also present itself as further effects of intense heat.

For indoor grows, this is commonly from placement or growth too near the lights.  This is especially true of High Intensity Discharge (HID) lighti9ng systems which generate significant heat.  A few days of strong growth and the upper leaves may be well into the 130 degree plus range of these bulbs.

For outdoor plants, consider the location in relation to reflective items or areas that store and contain heat such as sunken beds, areas around sheds and buildings, or near reflective surfaces and asphalt.

Solutions for both of these factors usually involves moving the plant or providing shade.  I'll cover some shade recipes and ideas in the future.

Some simple steps for avoiding heat injuries to your plants......

Move the plants away from the culprit (duh!).

Add additional soil to lower the overall plant temperature.

Add shading.

Keep plants at least 8-12 inches below HID bulbs and at least 2-3  inches from LED, and T5 and T8 bulbs.

Move the pants to full or partial shade if the type requires that environment.  No sense in killing a plant that has no business in the sun!

Cold Shock (Yellow Leaves)

Were the plants, especially potted plants subjected to a sudden drop of temperature such as being near a window on a cold night or a power outage?  The plant may yellow some lower leaves and drop them to conserve energy for what appears to be a "crisis.

First things first....get the plant to a stable environment with a room temperature within the recommended range of the plant.  Second, re-plant to a larger pot if additional temperature drops are expected in the future.  The additional capacity of soil will help insulate the plant and reduce the amount of shock during the cool-down periods.

Plants generally recover quite easily from unexpected cold shocks. Give it a couple weeks to sprout additional leaves or to halt any yellowing that may remain present.

Plant Age (Yellow Leaves)

Yellowing of older or "bottom" leaves may simply be a sign of age and the natural growth during the plant life cycle.

Check the new growth or "upper" leaves for signs of yellowing along the veins.  If there is no yellowing and the new growth appears healthy, it is very likely you have natural dying of older growth leaves and have nothing to fear. This process is essential for the plant to maintain it's strength as it shifts nutrient uptake to the new growth.

Relax!  But keep an eye on new growth leaves for any signs of discoloration.  Let those bottom leaves drop off and pop them into the compost pile! 

More to come.

Why are my leaves yellow?

Why are my leaves turning yellow?

Some common reasons for leaf yellowing:

1)  Plant age
2)  Cold
3)  Heat
4)  Depleted nutrients
5)  Sudden shock or change of conditions
6)  Injury to plant
7) Lack of oxygen
8) Disease.

I'll take a detailed look at each of these conditions over the coming weeks and add some timely "tips" and "remedies" to keep your babies healthy.

Deep Water Culture and Ebb and Flow

Here is a Deep Water Culture and Ebb and Flow System side by side comparison video.  Both are excellent systems and provide very efficient results.

Which one works best?  See the past blog entries on each systems attributes and weaknesses.

#4 Why a Deep Water Culture System?

Why Deep Water Culture System? 

Number 4) Easy to clean!!! Cleaning the system is always required after each grow to prevent any type of alage or fungus from taking advantage of your "perfect" environment. The Deep Water Culture System is probably the easiest to clean. 

Simply add a couple gallons of warm-hot water to the empty reservoir, add dish soap, the net pots (empty), and the airline tubing, and clean with a medium brush or dish rag. Once fully rinsed, add another 2 gallons of hot water with a 1/4 to 1/2 cup of bleach and sanitize everything to include the air stone. Rinse thoroughly and let dry. 

Too easy!!!

# 3 Why A Deep Water Culture System?

Why DWC? Number 3). 

Highly EFFICIENT and EFFECTIVE. 

Grow faster, stronger, and healthier plants without soil. My recorded results have shown increased harvest season and faster maturity over even the best prepared soils. These results are documented in the videos and the blog and amaze me to this day. 

 Nutrients and oxygen are delivered at just the right amount to insure the most explosive growth possible. Consider these factors and it is no wonder that a Deep Water Culture System is a model of efficiency in growing plants.

Why Deep Water Culture #2

Why DWC? Number 2). 

 Portable! The system is easy to move as one complete unit allowing maximum use of shade and sun. "Bubbling Bucket" DWC's can be moved easily by one person as long as the plant is supported!

Consider the weight of the nutrient solution if you are designing a "mobile" Deep Water Culture System.

"Bubbler Buckets" weigh in at around 40 pounds for the nutrient solution alone.  At 8 pounds per gallon, consider the need for draining or a two-person lift before finalizing your plans.

Also consider whether the reservoir has the strength to be moved while full or partially full.  No one wants a sloshing reservoir buckling and collapsing during a simple move from room to room or under lights to outdoors.

Deep Water Culture Versus Ebb and Flow

Continuing the "Deep Water Culture vs. Ebb and Flow" topic.....

Why DWC? Number 1). So cheap and easy to build with easily accessible parts!!!

Number 9) Why use an Ebb and FLow System?

Here's the 2nd Ebb and Flow Video showing use, lighting changes and details, and some additional "cycling" and nutrient tips. 

Considering the previous eight "why Ebb and Flow", it is a tough system to beat both economically and for efficiency.  It was by far the most fun to build!

Number 8) Why use an Ebb and Flow System?

BIG plants do not need to be staked and supported when checking and changing nutrients as with a Deep Water Culture system.

Change the nutrients while your babies remain undisturbed!

Number 7) Why use an Ebb and Flow System?

One large reservoir can feed multiple flood tables allowing many expansion opportunities!

Number 6) Why Use an Ebb and Flow System?

Number 6) The Ebb and Flow System is just plain cool to a gizmo nut! Controlled flooding and draining provides an exceptional growth environment while allowing the plants a versatile and stable growth platform.

45,000 Page Views!!!!!

Wow!  45,000 page views!

Thank you everyone for your interest in hydroponic growing.  I suspect we now have many, many more "hydro" gardeners growing their own and enjoying a very productive hobby. I am glad to have contributed to this in even the smallest of ways!!

I'll keep the blog up and running as well as the facebook page.  Don't forget to "subscribe" to the Youtube page as well.

Number 4 Why Use an Ebb and Flow System?

Number 4) 

Flow cycles can be adjusted to maximize nutrient uptake. Use a journal to quickly determine the most efficient ebb and flow cycle to save even more electricity.

Be as specific as possible when recording your results as this data becomes very valuable in making accurate decisions.  Experiment with feeding cycles in conjunction with light cycles.

Number 3 Why Use an Ebb and Flow System?

The Ebb and Flow system allows changing of nutrients and pH testing without disturbing the plants. A valve on the reservoir tanks makes it even easier!

Number 2 Why Use an Ebb and Flow System?

Number 2)   

The Ebb and Flow system provides a "blast" of oxygenated nutrients to the roots for short periods allowing the media to hold and maintain moisture during the ebb cycles. This gives the roots a larger quantity of fresh air expose and stimulates the plants natural reaction of expanding the root base.

Why Use an Ebb and Flow System?

Number 1)  

The Ebb and Flow system allows flexibility in nutrient temperature because of the separate reservoir. By having the ability to shade, mechanically cool (chiller), or even partially bury a nutrient reservoir, efficient temperatures can be maintained in the heat of the summer or the dead of winter. This keeps the roots from excesses and stress.
