Gas sites can be divided into two broad categories, WH gas and K-space (regular space) gas sites. WH Gas is used in the creation of T3 Cruisers and destroyers, and is found only in WHs. K-space gas sites are used in the creation of combat boosters aka. drugs. In general, WH gas is more valuable than K-space gas by volume, but the process of harvesting the gas is very similar. For the purposes of this guide, it will be assumed that you are harvesting the K-space gas in Catch, Lime Cytoserocin.

The equipment required to huff gas is fairly cheap, with a fitted Venture currently costing roughly 12 Million ISK. This will easily be made up after just one load of gas huffing, making huffing an extremely good return on investment. This makes it ideal for newer players who cannot afford more expensive ratting or mining setups to be able to make the isk they need to enjoy other aspects of the game.

• The gas harvesting skillbook represents a significant initial cost, with the skillbook going for roughly 24 million isk. The dojo does have this but requires a 24 million isk donation. Exceptions apply.¹⁾
• Gas huffing in Catch has one major risk not present for wormhole gas, the gas has a chance to explode on each attempt at harvesting the cloud. This means your fit must differ from a wormhole gas fit (fits below) and you may find it difficult to huff in groups.
• The loss of ventures should be expected as you go about your huffing adventures. Luckily they are cheap, so don't get too attached!

Before you can start huffing gas you must find a gas site. Gas sites are similar to relic or data signatures; Gas sites must be scanned down using core scanner probes. One way you can more easily track down these sites is to ask other explorers if they've spotted any nearby or use a signature tracking website such as https://afowl.si/deepsafe/ or https://pathfinder.bravecollective.com/ . Once you have found a gas site that you want to huff, grab your venture and get ready to go!

The venture fit should be cheap and effective. A good starting point is:

[Venture, Minimum Skill Duo Nebula]
Type-D Restrained Shield Power Relay

Medium F-S9 Regolith Compact Shield Extender
Medium F-S9 Regolith Compact Shield Extender
Limited 'Anointed' EM Ward Field

Gas Cloud Harvester I
Gas Cloud Harvester I

Small Anti-EM Screen Reinforcer II
Small Anti-Thermal Screen Reinforcer II
Small Anti-Thermal Screen Reinforcer II

Once you've trained up your skills but still cant fly a Prospect hull, then try this next fit.
(If you're having fitting issues, swap one or both of the Medium Shield Extender II's for the compact variant.)

[Venture, T2 Harvesters Duo Nebula]
Shield Power Relay II

Medium Shield Extender II
Medium Shield Extender II
EM Ward Field II

Gas Cloud Harvester II
Gas Cloud Harvester II

Small Anti-EM Screen Reinforcer II
Small Anti-Thermal Screen Reinforcer II
Small Anti-Thermal Screen Reinforcer II

1. Duo Nebula
2. Leopard Nebula
3. Remy Nebula

This is the easiest site for a newbie to get into and huff. Follow the following steps to get into a Duo Nebula and start huffing today. The clouds do 1000 EM and 1000 thermal, you should not do the same cloud with another venture.

1. Go to https://afowl.si/deepsafe/ and login
2. Click Search All systems
3. On the far right switch to Catch Region
4. In the middle switch to Gas Sites
5. Find the signature name of a Duo Nebula in a Brave system
6. Add a probe launcher and probes to your venture fit or do this before in an exploration ship.
7. Go to the system with the Duo Nebula
8. Tether on a structure and scan down the correct Signature ID from deepsafe. (Scanning Guide)
9. Warp to the gas site and bookmark it (recover probes and return with a venture if you aren't in one)
10. Pick one of the two Lime Cytoserocin in the Misc or mining tabs of the overview and warp to it.
11. Turn on EM hardener.
12. Select both gas harvesters at once and then target the gas cloud.
13. Mine until you're full.
