Galaxyhydro 300w LED - Small Tent - 2 Plants?


New Member
Long time lurker, first time poster and grower here and before I get ahead of myself I feel like I owe a thanks to all of you good people here. Had it not been for the detailed grow journals and advice here I don't know if I would have gotten this far into the growing process!

So to give you an idea of where I'm at - I ordered my seeds last week and am currently setting up my grow room. Due to space restrictions I had to settle on a 36" x 20" x 62 " tent that I'm hoping will support two plants.

I decided to go with a Galaxyhydro 300 W light I bought from Amazon. After doing a bit more research I'm learning that this may not have been the best light I could have purchased but with all the other things I'm buying right now it's the best I could afford.

So here's the ask: Has anyone successfully vegged and flowered with this light? Is it unreasonable to expect decent per plant yields with a 300 w light given this size of tent?

Should I return and get a different light before starting? I'm hoping since it's a small space, I can get away with using these lights and get a decent yield (IMO 2 oz per plant).

Thanks in advanced!

One additional note - I'm going to be mainlining these plants and shooting for 4-8 colas depending on space. I've seen people get redic yields this way but I'm also wondering if I should adjust my expectations based on these lights. This probably means a veg time of 6 - 8 weeks. I'll be growing Papaya from Nirvana Seeds and flowering from 55-70 days.

Last self reply... Other lights I am considering are

1. Apollo Horticulture 300 w
2. Marshydro 300 w
3. Marshydro 600 w ($75 more)

Think I have a week to figure it out!

Can work if done right but I would not try to start with advance training methods.
Special if they need a lot of time look for topping and bend them over.
If possible take the 600W Mars, all these use max 1/2 the W they are rated.
So a 300 has 130-160W real usage.

I've just started my first grow, and will be using two of the GalaxyHydro 300 in a 4x2 tent from seed to harvest. I'm planing to do mainlining as well. Hope it works out well for both of us.

If you look on the bay, you will find marshydro 300W lights for 70 dollars shipped. I would return the GH300 and get two of the marshydro 300 for about the same price as one GH300. I would then use both MH300 in that tent for nice coverage and yield.
