Putting together a new grow setup? You are probably wondering what basic elements you need. Whether you are working in a small tent or a full-scale greenhouse, there are certain supplies every grower should have.
In this video, Craig explains the equipment you’ll need to see success. Here, you’ll find a brief introduction to giving your plants adequate lighting, regulating your setup’s temperature, and promoting air circulation.

How Does Storage Temperature Impact Seeds?
Study performed on Hemp (Cannabis sativa L.)
Seedling lengths (measured in cm) were compared across the following number of storage months…
Storage Months: 0, 3, 6, 9, 12, 18, 24, 36
In addition at each storage month the moisture content of the seeds were also evaluated.
Moisture Content of Seeds: 5%, 7%, 8%, 10%, 12%
This was performed across three different storage temperatures
Ambient: 10⁰C (50F) winter to 40⁰C (104F) summer
15⁰C (59F)
-20⁰C (-4F)
Ambient Storage Conditions: 10⁰C (winter) to 40⁰C (summer)
The continual temperature fluctuations reduced the storage time across all seed moisture contents.
Only the 5% moisture content seeds were able to have germination past 9 months of storage.
15⁰C and -20⁰C Storage Conditions
Under these temperatures, if the moisture content of the seeds was under 10% seedling growth could still occur up to 36 months of storage
However, if the moisture content is 7% or less than seeds had similar seedling lengths
Look For Stated Moisture Contents…
How Should Cannabis Seeds Be Stored?
Low moisture content seeds (under 10% with 5% suggested)
Cool (under 15⁰C (59F)) and dark conditions
If you are looking to keep the seeds long term than taking the extra step to store the seeds in an environment that is -20⁰C (-4F) is justified.

The debate is on and people want to know whether LED grow lights or Fluorescent bulbs are better for Seedlings and Cuttings. In this video, we’ll do a direct comparison of the ViparSpectra XS1000 LED Grow Light and a shop light fixture containing 4-4foot fluorescent bulbs. We’ll look at the PAR they both put out. Same wattage, same height, both in grow tents appropriate to their size. Which one will win?

Dioecious or Feminized Seed?
Dioecious = have a 50/50 male/female ratio (theoretically)
Feminized = will produce a female plant
Dioecious Seed: Advantages
Have more genetic variability
Can produce pollen of chosen strain
Can offer more varieties to select from
Dioecious Seed: Disadvantages
Male plants will need to be removed (if not breeding)
Plants will have to be cared for that may not produce valuable yield
Will have to purchase more seeds than you need
Feminized Seed: Advantages
Vastly reduce the time spent culling male plants
Purchased seed number can more closely match total plant number
Cost? (Less expensive in some cases)
Feminized Seed: Disadvantages
Limited strain selection options
Can not use the seeds if you are a breeder
Potential negative impact on chemical profile
Cost? (More expensive in some cases)

The more I look at the health benefits of hemp seeds and in particular hemp hearts the more impressed I am. In this video we make the case for why we should consume 3 tablespoons of hemp seeds everyday. Loaded with protein and omega 3 fatty acids these little seeds are powerhouses of nutrition! In particular w look at hemp seeds impact on the heart, brain and bones.

Are LED sellers truthful with their efficiency claims? How can you tell? Who’s being honest? In this LED grow light video review, I decided to audit 4 popular Amazon vendors (Spider Farmer, Maxsisun, Mars Hydro & ViparSpectra) to see if their lights match the PPE product specs shown on their websites. Which companies are most truthful?
This review features 6 popular LED grow light models from the “1000” category. Some of them might be ok for a single “medicinal” plant. But these are ideal for home gardeners, growing things like lettuce, microgreens, seedlings & herbs. Three premium models: SF1000, MF1000 & TS1000. Three budget lights: SF1000D, PB1000 & TS600. Which lights are best? I took PPFD readings comparing the light levels. The video shows several other metrics for comparing these grow lights.
Be sure to watch Part 2: https://youtu.be/WmjOSzSF-HI
Although I reviewed & tested 6 LED grow lights, I’m only able to recommend 4 of them: SF1000, PB1000, MF1000 & TS1000. The SF1000D & TS600 are subpar units. Unless you can get them at a super cheap price, you’re better off just buying a PB1000.
• SF1000: Spider Farmer originally released this LED at $140. A year later, they had added a dimmer box & raised the price to $160. It wasn’t making any extra light. It just cost more. They originally listed it as PPE 2.7. Then they claimed PPE 2.9. This was false. Their Integrating Sphere test reports show the PPE is only 2.5! It’s still very efficient. It also has a higher percentage of Far Red light vs the other LEDs. So I do recommend it. But I would not pay more than $160 for it.
• SF1000D: Growers might mistake the SF1000D for a SF1000 without the dimmer. But that’s not the only difference! It has Samsung LM301D diodes. It doesn’t have a branded driver. And so the power factor is low (0.69). The efficacy is much lower. The PPE is only 2 (even though the label said 2.6). At $100 or higher, this light is simply not worth it.
• PB1000: Maxsisun’s budget grow light. Was a nice entry level light at a good price. Unfortunately, the company has not been doing anything in the market for a while now.
• MF1000: It has more features than the others: Ribbed heat sink, daisy chain power connector & remote control for power & dimming. The reflector hood helps to focus the photons (along with a smaller diode footprint). It doesn’t output much more light than the PB1000. But it distributes the light differently (good for non-tent applications). The PPE is slightly higher (2.139 vs 2.077) & it includes a Far Red diode. But it has that premium price too. If you’re impressed by the features, then it’s worth it.
• TS600: Mars Hydro didn’t want me to review this light. They had NO test report. It had false PPE specs on the label (PPE 2.3). Probably more like 1.8 umol/J, based on my PPFD readings compared to the MF1000 (which matches wattage & also has a reflector hood). The TS600 has a poor power factor (0.7). It’s not very bright & not as efficient. I don’t advise buying it.
• TS1000: Unlike the other 100W models, this LED is a full 150W. So the output is much higher! I was given an old test report. But my PPFD readings support an efficacy of 2.1 or even 2.2. It would be fair to compare this light to the others, except it costs LESS than the SF1000. And you can dim it too. A good value in that more expensive premium category!
There is no mystery to grow lights. You might even be able to use something you have at home. In any case, I’m going to break down three different types and prices of grow lights and let you know the pros and cons of each.
Remember the numbers… LUMENS: 1500-2000 Kelvin: 4500-6500
