Grow vegetables indoors all year from seed to harvest using Active Grow sunlamps. I started out with the Active Grow SunWhite 8 lamp T5 fixture. My tomatoes, peppers, and cucumbers did so well that I decided to convert all my T8 fluorescent fixtures into ballast free to use T8 Active Grow SunWhite bulbs too (T8 review starts at 2:23). I have harvested so many awesome tasting vegetables. My lettuces did phenomenal under these grow lights. The hardiness and texture were way better than when I was using full spectrum fluorescent. Check out my YouTube videos at Amelia's Indoor Garden. To top it off they are located here in the US with excellent customer service. They truly have a passion for their product.

These seedlings I started about 5 weeks ago are now thriving in my garden. I usually supplement those plants with others I pick up at the nursery to fill in gaps. Not this year. Retail inventory of seedlings was horrible, and so was the quality! And my latest happy discovery this seed-starting round is my new grow lamp system. I love trying different lighting systems in hopes of finally settling on a favorite. Over recent years as I was creating my Master Seed-starting online course, I trialed many options from basic fluorescent shop lights, to high-end LED rigs and more sophisticated T5 fluorescent systems. Recently I was invited to try and keep (at no cost to me) a 24W T5 lamp and fixture from Active Grow. I've trialed several more basic LED shop light rigs in the past but the results were just average. But not this one. It's definitely got my attention. These lamps were clearly designed for indoor growing, with high PPF efficiency (the amount of quality light frequency usable by the plants), and higher energy efficiency (none of the heat energy wasted by the fluorescent alternatives). Over 5 weeks of growing time under this system, the plants performed very well - no legginess, nice compact plants, great color, and no light-burn. You can buy just the lamps that plug and play into existing T5 fluorescent fixtures (4 lamps cost about $139), or you can buy the lamps and fixture for around $219 for the 2x4 ft size - perfect for evenly lighting 4 standard trays on a self. The seedlings here were growing under the Sun White Pro lamps and I was very happy with the results. I'm really looking forward to seeing how it performs for the next round of warm-season edibles starting in February. A link to this lamp system is in my instagram profile (@joegardener). (Not an affiliate link). What's your favorite grow light system?

high performance, low cost. This lamp has been phenomenal since turning it on from day 1, I noticed immediate growth improvement. I could not be happier with the performance of these lamps and recommend to anyone.

Performing LED at excellent value. Amazing light. Almost no heat output - be sure to plan for that! Also, the switch allows you to turn on only 2 or all 4 bulbs. I thought the fixture was broken at first but it turned out to be an added feature - BONUS ! Support was also very responsive when I messaged them with a question. I will buy again.
