I would suggest marshydro 300w to start out with, A lot of us here have that model and they do a good job growing carnivorous plants! Best value for our budgets really..
The reason why they don’t have it on their main site anymore is because it’s a older model (one of their first models). They use their website to show off their newer more expensive models to try and keep up with the bigger brands!
They use eBay really for a means to continue to sell their older models!
I have 4 marshydro 300w, as for the other brands idk never had any exp with em
According to marshydro their Marshydro 300w has a max of 2’ by 2’ foot coverage! At 18” to get the par output in their diagram below but u really will have to experiment with your plants to see what’s the best height! Of course the higher it is the more coverage their is at the expense of the par that reaches your plants! They also say the lumen output is about 5911.
To tell u the truth really from what I’ve looked at on the web theirs not much of a difference between the brands u listed when it comes to “coverage” but they did very on the amount of par they created at the same distances!
Anyways I suggest the marshydro 300w lol
