I would stick with the 75 watt. I use a 54 watt for my seedlings and to root clones. It takes longer yes. But seeds and clones neee minimal light. if you add too much light , it could be to intense amd kill them. Plus adding extra light an heat can lean them towards being male. Low wattage and cool temps and low humidity for seedlings will almost guarantee female. I have never had a male in all my years. Once the roots have establishes themselves ( 2 or 3 new nodes). Then add more light. Keep temps cool.i just dont think they are getting the light they need i have 5 seedlings under a singly 75w t5
they are all vigerous lil boogers except for the shy one who still has her seed shell but she is just as tall as the outhers
found a replacement for the 454

Its a little more expensive. But NOT on back order =D
Liquid light...... Yeah I've used that before. I was the guinea pig for my local shop. It works really great but you have to buy that penetrator or saturator depending on where you buy it. Seen with either labels. I think they changed the name at one point. and mix them and spray every other day. I went through it in a month. It works great and I definitely saw a positive difference but it costs way too much. Liquid light - $60, Penetrator - $50.you have to use up the whole mix you make. Once it mixes together. It starts breaking down rather quickly.
+rep!!! How did you get it done? (out of curiosity)Did the spectral analysis for the Fiji Purple today.
Here it is finally!
Enjoy,
awesome! thanks for doing this... did you read any other bulbs? I confess that I am curious how your spectrometer results compare to published spectrum graphs =DMy old physics teacher uses a spectrometer in his lab. The readings above 800nm is just noise so you can ignore that. So basically it is an actinic/blue light with a touch of red. No 660nm though.
I didn't have a reason to, although it did cross my mind. It was hard enough just to get the one graph. He is an extremely busy guy! The spectrometer is a really simple instrument. Small box that attaches to a computer on one side and a fiber optic sensor on the other. The sensor looks like a little maglite flashlight. It would be cool to own one. I really wanted to do an analysis of my entire mixture of bulbs, but like I said, we are really lucky to even have this one.awesome! thanks for doing this... did you read any other bulbs?

Bellissimo!!! Finally we know about the elusive Fiji! You should email Korallenzucht them and tell them that you're going to send this graph UVL, ATI, and Wavepoint so they can all make bulbs that will crush the Fiji sales! That's what they get for being so dickish about not releasing their sacred spectral graph.Did the spectral analysis for the Fiji Purple today.Here it is finally!Enjoy,View attachment 2005223
