About This Setup
The 600W HPS is one of the most powerful and efficient setups you can buy to grow your own cannabis at home. Although the technology behind it is archaic, there’s no denying the high-yielding, high-potency power of the might 600W HPS. Part of the true power of this light comes from the fact that it can be kept so close to plants (as close as 8-10″) while lights of similar wattage have to be kept much further away (18″+).
Pros: Crazy yields, super high potency, most electrically efficient HPS, relatively cheap to buy
Cons: Old technology, emits suspicious yellow light, poorly-made models emit RFI, can get pretty hot
- Setup Cost: $780.00
- Estimated Electricity Cost: $61-128/month (based on $0.12/kWH to $0.25/kWh – see breakdown)
- Total Cost for Entire First 4-Month Grow (Setup + Electricity): $1292 ($61-130/ounce)
- Total Cost for Second Grow (Nutrients + Electricity): $542 ($26-54/ounce)
Complete Grow Supply List
This cannabis grow room setup list includes all the supplies you need to get to harvest.
- iPower 600 Watt HPS MH Digital Dimmable Grow Light
- A 600W HPS is great at growing weed, but it’s even better when paired with an MH (Metal Halide) bulb which is used in the vegetative stage.
- Recommended: iPower 600 Watt HPS MH Digital Dimmable Grow Light
- Cost: ~$200
- * Alternative/Equivalent LED Grow Light: VIPARSPECTRA V1200 1200W LED Grow Light
- Grow Tent Recommended Sizes
- Exhaust Fan
- When you’re growing enough weed to fill a 4×4 tent, you need to make sure that smell isn’t escaping. A good fan and a reliable filter will take care of this problem.
- Learn more about choosing and setting up an exhaust fan.
- Recommended: Can Max 6″ Fan – 420 CFM
- Cost: ~$145
- Carbon Scrubber
- Growing medium: Coco coir or soil. Hydroponics will really shine in a setup with a 600W light.
- Containers: Smart pots or Air Pots between 2 and 7 gallons
- Recommended: Two bags of this coco potting mix which is enough to fill 5 x 5-gallon smart pots. If you’re really feeling daring, hydroponics will excel here!
- Cost: ~$115
- You need a “vegetative” or all-purpose plant nutrient for the first part of your plant’s life
- You need a “bloom” or low-nitrogen nutrient for the budding phase
- Many nutrient systems have a nutrient schedule so you give your plants the right ratios for each stage of life
- Always start at half strength with a new base nutrient system because the recommended strength is typically too high for cannabis
- Get examples of great cannabis nutrients
- Recommended Base Nutrients: General Hydroponics Flora trio (use at half strength) + CaliMagic (use at full strength)
- (Optional) Bloom Supplement: General Hydroponics Floralicious Bloom
- (Optional) Root Supplement: Botanicare Hydroguard
- Cost: $50-100
Other Supplementary Items
- Get your seeds – $5-12/seed (on average, can be more or less depending on the breeder)
- 24-Hour Timer (to put your grow lights on a timer so the plants get a day and night period on a schedule). Why do cannabis plants need to be on a day/night schedule? What about autoflowering light schedules? – $10
- Water containers (I personally use a 3-gallon or 5-gallon water jug to mix up nutrients, but anything can work) – Much cheaper at Wal-Mart ($5-15) than online!
- 6″ Ducting and Ducting Clamps – to connect your fan and carbon filter together – $15
- Extra pair of 1/8″ Rope Ratchets (sooooo handy) – These can be used to hang your grow light or carbon filter from inside the tent, and still be able to easily move it up and down without needing any strength. Your grow light usually comes with a set of rope ratchets, but it’s a great idea to get an extra set to hang the carbon filter – $10
- Thermometer/Humidity Monitor with a probe so you can keep track of the temperature inside the tent – $15
- PH Test Kit – Prevent potential nutrient deficiencies by testing the water pH: https://www.growweedeasy.com/ph – $15
- Measuring spoons for measuring out your nutrients (many people already have these) – $10
- Learn about other cool growing tools
Estimated Cost: $940 plus the cost of seeds
A carbon scrubber prevents odors from leaking out of the tent in the flowering stage
On average this setup yields 10-21 ounces
