Ahhh, the germination stage. Can be nerve-racking and fun at the same time. Nobody likes to wait, but know that you’re putting your seeds in good hands as the BLOOM regulates the various environmental conditions needed for proper and swifter germination. The key factors that allow a seed to germinate are your water to air ratio, and temperature. BLOOM provides perfect temperature and water/air ratio (our peat pods are pretty special). The #1 other influencer is seed freshness/viability, so always make sure you are storing any unplanted seeds in a cool and dry location to maintain their viability.

We recommend planting 3-5 seeds into your Grow Pod to start as this will increase the likelihood of germination. Know that for most varieties of plants, you will want to trim the weakest links and leave the strongest stem to continue to grow.

Also, keep in mind that the number of days to germination will vary depending on the type of seed, so it is important to not compare apples to oranges. Here are some average times to germination for several types of plants:

Tomato – 5-10 days
Cucumber – 5-7 days
Pepper – 7-21 days
Eggplant – 7-14 days
Strawberry – 14-28 days
Lettuce – 2-10 days
Basil – 7-10 days
Cilantro – 7-10 days
Cabbage – 5-8 days

The moral of the story is to trust your BLOOM and do some research on the most ideal temperature for your little seedlings. You can customize temperature and light on/off time in your grow recipe and we’re more than happy to assist you in creating the perfect recipe that your plant will need to germinate and thrive. Post any recipe questions or requests for help in our “Recipe Discussion and Requests” category. Happy growing!

Thinning and Pruning are extremely important for all plants, so let's talk about these tasks and how to do them. Thinning is the process of clipping out the weakest seedling and leaving the strongest behind to grow strong and tall. It might seem counterintuitive to clip out all but one seedling, but trust us. This will allow your plant to receive the nutrients it needs and your plant will still take over the Bloom and eventually produce lots of fruit!

How to Thin your New Seedlings:
When your plant is about 1-2 inches tall, gently clip away the weaker seedlings from the bottom, and leave the strongest one to grow.

Pruning Young Plants:
When your flowering plants have about 3-5 nodes on the main stem, you'll want to "Top" the plant. Topping will control the size of the plant as well as create more main stems that eventually produce larger and higher quality fruit. This will encourage the plant to grow outwards vs. only up.

How To Top:
Trace the main stem up to the 4th, 5th, or 6th node (depends on plant, use your best judgement or reply with a photo if you need help). Clip the main stem slightly above the node.

This is how it would look after topping if done correctly:

Now your plant will grow two more branches instead of growing only upwards from the main stem. Every time you top, you're turning that one branch into two.

TIP: Be sure to do your last topping BEFORE the flower cycle begins. Make sure the branches are mature and well-established.

Pruning Mature Plants
You'll want to prune throughout the entire life of the plant. Don't be afraid to cut off leaves or weak branches as this will send the nutrients to the stronger parts of the plant and increase light penetration.

If you need help deciding when and how to top or prune, post detailed photos of your plants in the "Show Your Grow" category or "Questions and Answers", and we'll do our best to help!

Welcome @DJ and great questions!

The BLOOM uses a "Flood and Drain" system. This means that the system AI will regularly flood the grow tray with the nutrient-rich water and then drain it so that your roots can intake the optimal level of nutrients set by your grow recipe and the water can remain oxygenated.

In regards to the "two vented pumps", I believe you are asking about the irrigation pump. This pump runs the nutrient-rich water up into the grow tray and then back down into the Nutrient Reservoir.

A mixing pump is constantly mixing the nutrient and water solution to maintain the proper nutrient PPM (parts per million) and pH levels that are pre-determined by your grow recipe.

When transplanting a rooted plant into your BLOOM, be sure to inspect it thoroughly for unwanted mold, mildew or pests. It is very important to spot and eliminate potential threats to your young plant otherwise they can compromise the whole growth cycle. If there is a pre-developed issue that is allowed to flourish unseen, it will be difficult to combat and in the long run, very challenging to clean the system of the now established organism.

What to look for and where:

When a rooted plant that is ready to be transplanted into your BLOOM, inspect it from top to bottom.

Starting with the leaves to stem:
Make sure there is no white powdery looking mildew, webs or larva on top and UNDER the leaves. Pay careful attention to the bottom side of the leaves near the veins. Dormant pests may have laid their eggs there waiting for the proper environment to hatch and colonize. These eggs are surprisingly small and hard to see. Look for any spider-like webbing or mildew on the tops of the leaves and in between the leaves and stem.

Roots:
Transplanting hydroponically grown plants is beneficial to reduce the amount of vegetation time between flower cycles. Make sure the roots look healthy, strong, and white in color. Beware of root rot, which will look brown and slimy.

If you find any of these do not put the plant in the BLOOM. Quarantine it with IPM (integrated pest management) strategies or start over if it is obviously infested.

Hey all - Just here to add a quick note for when you're draining your main Nutrient Reservoir. The process is very easy and the Control Panel will walk you through the steps. Be sure to have a bucket ready for the process.

Additionally, do not worry if you hear a loud noise coming from your pump when your reservoir has about 2 inches of water left to drain. This noise is perfectly normal and is just the sound of the pump doing its' job.

Here's a video where you can hear what is to be expected.

You should drain and refill your main Nutrient Reservoir every 2 weeks (your Stage Change alerts will remind you to do so). This will help maintain the proper nutrient balance that your plants will want and need for optimal growth.

This may seem obvious to some, but with plants growing so rapidly in later stages it can be easy to forget to check your water level in your Nutrient Reservoir. The bigger the plant, the more water it will need so water level will begin to lower in your reservoir at a faster rate. Yes, BLOOM will alert you when your water level is low, BUT lower water levels (even showing medium) will create a higher ratio of nutrients in your reservoir, causing your PPM to be over the range.

If PPM is just a few hundred points over target, your plant will still be OK. A quick solution to seeing your PPM above range is to add water to the nutrient reservoir and let the system dose it back within range.

Did you know that you can find out just about anything you need to know from the Control Panel? Don't be afraid to tap around to learn more about your grow recipe targets, system and component details, and more!

Some of you have been wondering what the tube and vials are that are secured to the back of your Light Blocker.

The long tube is the Drain Tube that you will eventually use to drain your main Nutrient Reservoir. It is recommended to drain and refill your Nutrient Reservoir every 2 weeks during a Stage Change. Your control panel will remind you to do so and you'll have the option to complete the water change or skip it. The Control Panel will walk you through the steps to draining when you choose to do so. It is as easy as hooking up the Drain Tube to the mixing pump and tapping "Drain" on the Control Panel and placing the other end of the tube into an empty bucket.

The other two vials are labeled PPM and pH and these are your PPM and pH Calibration vials. You'll want to calibrate the PPM and pH sensors after finishing a grow and before beginning a new one. If you go to the Main Menu and select "Calibration" you will be able to learn more and start the calibration process when you're ready. Two different calibration solutions will be required for this step and will be available for purchase on our BloomGrows.com website.

Welcome to the world, Tom! Keep the updates coming @pg13!

@BG1164 We're happy you're here and we couldn't agree more. The BLOOM is a beauty and will look even better when those Black Beauty Eggplants start growing! Keep us all updated on your growth. :)

These are absolutely beautiful! We don't doubt that they'll keep producing long after 6-7 weeks due to their ideal environment in the BLOOM. Certainly keep us up to date on the life span you observe.

@MichiJuana How is everything going with your first grow?

How is everybody enjoying the new update?

Please let us know if you are seeing any issues at all, large or small! Thanks everyone!

Hey Everyone!

We just want to stress the importance of pruning as much as you can when growing inside of the BLOOM. There are several reasons why it is so important:

1. Space is limited in the BLOOM - this is the most obvious reason, but you want to prune to avoid having your plants grow into the lights. The top lights are 250 watts and the side lights are each 25 watts. This generates a lot of heat and the lights can burn your plants if they get too close.

2. All plants transpire in order to move water throughout their stalks to the branches and leaves. This means that as the plant is larger, you won't need to fill the humidifier as much because the plant is busy converting the water it takes up to a gas. If you start to see a "steam room" effect inside the BLOOM, you should consider how large your plant is and prune wherever possible.

3. Pruning encourages new growth in the plants and because the BLOOM provides the perfect environment, you WILL see faster and more frequent growth. It may feel "wrong" to prune early on, but you will quickly notice that the plants will bounce back and be stronger than ever!

Post to the forum if you have any questions about when/where/why to prune your specific plant. Yes, there is a lot of information out there to help you, but be aware that a lot of the tips on the internet are geared towards outside growing vs. the controlled environment of the BLOOM. Our BLOOM experts and community members are always happy to help!

Hi, @DJ. We had a chance to look at your system data and see that you are in the "Drying" stage.

First, a couple questions:

Is your plant cut and hanging and are your lights off?

We can see that your heater is working (we've observed an increase in temperature to 61 at certain points), but we believe that the heater is essentially battling the radiator which works constantly to help maintain target humidity levels. The heater will only kick on for 2 minutes at a time to avoid overheating and frying the plants.

We appreciate the data and are looking into how we can make both systems work in conjunction with each other more consistently. For now, having a temperature of 60 vs. 65 is totally OK and it is more important to have the system work to control the humidity levels than to constantly heat during this stage.

Please let us know if you notice anything else and reach out if you need additional help.

Hi @twotoedtheory. How is your grow going? Post in the "Show What you Grow" category when you can. Thanks!

@northern_dweller How is your first grow going? We'd love to see your plant's growth. Post in the "Show What You Grow" category to keep us all in the loop!

So beautiful!! What a fun BLOOM grow!

@greenwings Congrats on your first harvest! We can't wait to see how the second grow goes!

@Rainville Are you getting alerts when the reservoir is still full?

The humidifier will run fairly constantly when plants are young. As they mature and get larger, the plant will resperate and put off moisture, so you'll end up needing to fill the humidifier way less frequently.
