Razloženo spodnja deska: velikosti, slogi in kako izbrati

The downstem is one of the most critical components of your bong - it's where smoke enters the water for filtration. Store your cannabis properly in Stekleni kozarci to maintain quality. Understanding downstem sizes, styles, and how to measure ensures you get the right replacement or upgrade. This guide covers everything you need to know.

hiter odgovor

Spodnja stebla so na voljo v dveh velikostih spojev: 14 mm in 18 mm. Measure your bong's joint (a dime is slightly larger than 14mm) and the length from joint to 1 inch above base. Diffused downstems (with slits/holes) provide more filtration than open-bottom styles. Most bongs use 14mm joints; larger pieces use 18mm.

Kaj naredi Downstm?

Spodnja stebla povezuje vašo posodo z vodo, ki služi dvema bistvenima funkcijama:

1 Dostava dima: Prenaša dim iz sklede skozi sklep in navzdol v vodo.

2 Osnovna filtracija: Ustvari mehurčke, ki filtrirajo in ohladijo dim pred vdihom.

Brez spodnjega stebla bi dim vstopil nad vodno črto brez filtracije. Spodnje steblo je tisto, zaradi česar je bong bong in ne suha cev.

Velikosti sklepov: 14 mm proti 18 mm

14mm spoji

Najpogostejša velikost. Used on:

• Majhni do srednji bongi (8-14 palcev)
• veliko čaše
• Večina mehurčkov z odstranljivimi spodnjimi stebli
• Standardne cevi za vodo

Kako prepoznati: Dime (premer 17,9 mm) je nekoliko večji od 14 mm odprtine spoja.

18mm spoji

Večja velikost za večje bonge. Used on:

• Veliki bongi (14+ palcev)
• Težka znanstvena stekla
• Nekaj vrhunskih kosov
• Veliko ravnih bongov

Kako prepoznati: Dime je nekoliko manjši od 18 mm odprtine spoja.

Preizkus hitrega dimnika

1 Držite dime nad odprtino sklepov

2 Če je dime večji od odprtine = 14 mm

3 Če je dime manjši od odprtine = 18 mm

4 Če se dime natančno prilega = neobičajno 18 mm (dejanski so vedno nekoliko večji od 18 mm)

Merjenje dolžine navzdol

Pravilna dolžina je ključnega pomena - prekratka ne bo dosegla vode, predolgo zadene bazo.

Kako meriti:

1. način - z obstoječim spodnjim steblom:

1 Odstranite spodnjo deblo iz Bonga

2 Izmerite od dna zmrzljivega spoja do spodnjega dela

3 To je vaša dolžina navzdol

2. način - brez dna:

1 Vstavite svinčnik/palčko v sklep pod kotom navzdol bi sedel

2 Označite, kje se sklep konča na palici

3 Spodnja palica, dokler se skoraj ne dotakne osnove (pustite 0,5-1 palca vrzeli)

4 Označite to točko

5. Izmerite med oznakami

Skupne dolžine:

• Majhni bongi: 3-3,5 palcev
• Srednje bongs: 4-4,5 palcev
• Veliki bongi: 5-6 palcev

Important: Vedno pustite vrzel med spodnjim delom in podnožjem. Udari v bazo:

• Omeji pretok zraka
• Lahko razpoka steklo
• ustvarja nadležno ropotanje

Slogi navzdol

Odprto dno (nerazpršeno)

Preprosta cev z odprtim koncem.

Pros:

• Največji pretok zraka
• Enostaven za čiščenje
• Najcenejša možnost
• Won't clog

Cons:

• najmanjša filtracija
• Večji mehurčki = manj gladki
• Osnovna izvedba

Best for: Uporabniki, ki dajejo prednost pretoku zraka pred gladkostjo, proračunske gradnje

Difuzor z razrezanim

Na dnu je razrezana cev s 3-6 režami.

Pros:

• Več mehurčkov kot odprtih
• Boljša filtracija
• Dobro ravnovesje pretoka in gladkosti
• Skupna in cenovno ugod

Cons:

• Lahko se zamaši s smolo
• nekoliko več povleci
• Potrebujete redno čiščenje

Best for: Večina uporabnikov - dobra vsestranska zmogljivost

Difuzor z več režami

Številne reže (8-12+), ki ustvarjajo fino difuzijo.

Pros:

• Zelo gladki zadetki
• Odlična filtracija
• Veliko majhnih mehurčkov
• Odlično za ostro cvetje

Cons:

• Most drag
• Zamaši se hitreje
• Težje očistiti
• Višji stroški

Best for: Uporabniki dajejo prednost gladkosti pred zračnim tokom

Difuzor za prho

Raztegnjeno dno z luknjami, razporejenimi v krogu, kot tuš.

Pros:

• Tudi porazdelitev mehurčkov
• Gladka zmogljivost
• Zanimivo vizualno
• Dobra filtracija

Cons:

• Lahko je krhka pri izbruhu
• Zmerna povle
• težje najti

Best for: Uporabniki, ki želijo edinstven slog difuzije

Drevesni perkolator navzdol

Več rok z režami, ki segajo od spodaj.

Pros:

• Največja difuzija
• Very smooth
• Impressive visual

Cons:

• Fragile
• Hard to clean
• Significant drag
• Expensive

Best for: Smoothness enthusiasts with careful habits

Material Options

Borosilicate Glass (Standard)

Most common. Heat-resistant, durable, easy to clean. Clear glass lets you see diffusion. The standard choice for good reason.

Quartz

Premium option. More heat-resistant than borosilicate, very durable. Usually clear or slightly different appearance. Overkill for most users but appreciated by enthusiasts.

Silicone

Flexible and unbreakable. Some silicone bongs use silicone downstems. Won't break if dropped but may retain odors over time. Good for clumsy users.

Titanium

Rare, very durable. Virtually indestructible but changes heat transfer characteristics. Expensive and uncommon.

---

Matching Bowls to Downstems

Your bowl must match your downstem's joint size:

• 14mm downstem = 14mm male bowl
• 18mm downstem = 18mm male bowl

Using Adapters

Can't find the right bowl size?

• 18mm female to 14mm male adapter: Uses 14mm bowl with 18mm downstem
• 14mm female to 18mm male adapter: Uses 18mm bowl with 14mm downstem (less common)

Adapters add height and can look odd, but work fine functionally.

Built-In vs Removable Downstems

Removable Downstems

Most bongs have removable downstems.

Advantages:

• Easy to replace if broken
• Can upgrade to better style
• Easier to clean separately
• Can adjust length if needed

Built-In (Fixed) Downstems

Some bongs have integrated downstems.

Advantages:

• Nothing to break separately
• Cleaner look
• No joint wear over time

Disadvantages:

• Can't upgrade
• If it breaks, replace whole bong
• Harder to clean thoroughly

Cleaning Your Downstem

Downstems get dirty fast - all smoke passes through them.

Quick Clean:

1. Remove from bong

2. Rinse with hot water

3. Use pipe cleaner for slits

4. Repeat weekly

Deep Clean:

1. Soak in isopropyl alcohol (91%+) for 30 minutes

2. Add coarse salt, shake in bag

3. Use pipe cleaners for slits

4. Rinse thoroughly

5. Dry completely

Preventing Clogs:

• Clean regularly before buildup hardens
• Use screens in bowl to prevent debris
• Change bong water frequently

---

When to Replace Your Downstem

Replace if:

• Cracked or chipped (safety risk)
• Slits are permanently clogged
• Joint is worn/loose (wobbles)
• Want to upgrade diffusion style

Average lifespan: 1-3 years with good care. Glass can last longer if handled carefully.

Choosing the Right Downstem

Consider your priorities:

Prioritize smoothness?

Choose multi-slit or showerhead diffuser

Prioritize airflow?

Choose open-bottom or 3-4 slit diffuser

Prioritize easy cleaning?

Choose open-bottom or minimal slits

Prioritize durability?

Choose thick glass, avoid tree percolators

Budget Guide:

• Basic open/slitted: $5-15
• Quality diffused: $15-30
• Premium/specialty: $30-50+

Pro Tips

Tip 1: Buy a backup. Downstems break eventually, and having a spare means no interrupted sessions.

Tip 2: Measure twice, buy once. Wrong size is useless.

Tip 3: More slits isn't always better. Consider your lung capacity and airflow preference.

Tip 4: Diffuser downstems can reduce your need for additional percolators, saving money and complexity.
