I didn't catch what is perceived as "not good." But, it's not hard to grow. Keep it simple. The biggest challenge is learning to let the plant grow, not "killing the plant with kindness," reading the plant. It doesn't require anything sophisticated to get through that learning process. Just a good environment (well-drained, airy soil; balanced fertilizer; water at 150'ish ppm).
@GrowUrOwnDank tagged me about the LED lightbulbs I use. Your CFLs will work. They will generate considerable heat. But, in the winter that may be desirable.
If/when you buy more lights, I would try GE's BrightStik's. They're $3.50 (US) each. The reason I like these lights is that the
diodes face forward (very efficient by design for directional lighting. See
these teardown images.).
Efficiency of a light is confusing. Your cool-white CFLs produce 63 lumens per watt. That's fairly typical for CFL. The Cree LED lightbulbs I use are about 90 L/w (with the protective rubber gummy-film removed from the glass diffusion globe).
The problem with either of these lights is that they are
omni directional. We want the light to go in one direction. So, those lumens are either lost or
reflected in the desired direction. Reflecting light is a loss too.
That's why the GE BrightStik looks more efficient to me. I doubt the diodes themselves are more efficient than the Cree diodes. And, the product packaging (72 L/w) doesn't sound more efficient than the Cree lightbulb's packaging (84 L/w, but removing the gummy protective coating takes it up closer to 90 L/w). But, the way the
diodes face forward, less light must be reflected. It also makes it less of a shock hazard to remove the plastic diffusion dome (which is a loss). For example, the Cree LED lightbulb has a tall metal tower (suspending a circle of diodes facing sideways). That begs for accidental contact. The way the GE's diodes are flush mounted to the base, there's very little risk of accidentally touching an electrified surface.
(Technically, you should power these with a CFI (ground-fault interrupter) outlet to be completely safe. But, the risk is so minimal/manageable with the surface deep within a reflector... I don't worry about it.).
I want to grow a plant exclusively with these to see how it goes. But, so far, measured in a reflector, these produce 20-25% more light than the equivalent 9.5w A19 Cree LED lightbulb. That makes them about 110 L/w (by comparison, mostly due to the design, I think.).
If you get some, be careful cutting off the plastic diffusor. You don't want to cut too deeply (too flush) with a hacksaw and hit any of those flush-mounted parts. You want to cut shallow all the way around.
