I bought an off-brand hydroponics kit back in 6/2021, grew about 3 cycles & put it away for 1 to 1-1/2 years until las week. Pulled it out & pump isn't working, so bought this & got it this morning. Took inserts with seeds out & moved to the new unit. You need to know some basics to succeed: 1. pH OF WATER: You really must test the pH of the water before planting, which should be 5.5-6.5 for lettuce, herbs, etc. I try to keep it near 6.0 generally. You need a pH meter kit to do this that has solutions to mix with water to calibrate it. Tap water here in Colorado & bottled water like El Dorado and Arrowhead usually test 7.5-8.5. I use General Hydroponics pH up & pH down to adjust. To adjust your water, just add 1/8 tsp at a time of Up or Down and retest, etc. until you reach near 6.0. This pH adjustment is important when growing hydroponically. Check the required pH for growing because certain plants grow best with a more acidic or alkaline environment. Everything I've grown before & now are around 6.0 pH. 2. HYDROPONIC FERTILIZER: I bought a 3-bottle kit of General Hydroponics hydroponic fertilizer (organic) after using what came with my 1st kit. Very easy to use & they have charts on what mixture for each stage of growth. The mixture changes from seedling to green growth to fruiting. The solutions don't go bad & they have worked fabulously for me. 3. NO TALL & SHORT PLANTS TOGETHER: If you try to grow tall plants (peppers, tomatoes, cucumbers) with low-growing plants (lettuce, herbs like thyme/oregano), the tall plants will kill off the low-growing plants as they mature, so think ahead. My jalapeno peppers & tomatoes killed off all my lettuce & herbs the 1st time. 4. TALL PLANTS NEED PRUNING: If you grow tall-growing plants like peppers & tomatoes, you will have to constantly prune to keep the growth manageable & to get flowers & fruiting. 5. POLLINATION: Certain plants have to be pollinated or cross-pollinated by hand, so do your research. You can do this with a paintbrush or even with your finger (called tickling the flower). I had many flowers on my jalapeno plant that never fruited. I did actually get some cherry tomatoes, but these tomatoes would normally grow to 4-5', so it was a chore of pruning & pollinating flowers to get just a few tomatoes at the time. If you don't do this, you will get flowers & no fruit at all. Plants like tomatillos need 2 different plants to cross-pollinate (male & female). 6. OTHER GENERAL: I don't soak seeds generally. Certain harder seeds can benefit from soaking. As well, what temperature certain plants grow well at can vary & you need to keep this in mind. Leave the caps on growing seeds until you can see at least 2 leaves & a bit of height (like in my picture); leaves reach top of dome over them. I planted these seeds last week in the old unit where pump wasn't working. On the left, I have 5-6 loose leaf lettuce plants. On the right, I believe it is arugula showing. The thyme, oregano, marjoram & spinach all have small sprouts coming up under the caps. Apparently I have one I'm not sure of at this moment, but I will know when it comes up, and 1 empty slot. 7. PUMP: I will edit the review if something happens with the pump. It is very quiet compared to my other one. I can feel the vibration when I put my hands on the side, but I don't see moving water when I look into the water. Without a working pump, the plants will die before maturing. 8. CLEANING: Keep an eye on the water. As plants mature, the roots will be too long & tangled to safely take out individually. Keep an eye out for a lot of algae (greenish), too much sliminess, etc. Brownish color doesn't necessarily mean you need to change water. I think I had to change water once in the first 3 growing cycles I did. You will have to take the whole top off, dump the water, clean out base, & then fill with new pH adjusted water with new fertilizer, then put base with plants back on. ALWAYS thoroughly clean and sanitize the base & plastic inserts between growing cycles (mild soap & warm water should be fine, but check your instructions). I hope this helps some newbies as I often see newbies leaving comments that nothing grew or died halfway. Measuring the pH is really important because tap & most bottled water is too alkaline. Invest in a pH meter & calibration kit. I just put the seeds in, fill up the water, & let it go. This is my 4th cycle of growing and you can see the seeds are all coming up. I may add pix after the plants start to mature more. Even though my last off-brand hydroponic system had 14- and 16-hour cycles, it only cycled 14 hours and everything was fine. As well, the timer didn't work well & time on/off would increase about 15-20 minutes probably every week; I just reset it if I was up early enough to turn it off/on again. So cheap, yes, but it worked just fine overall.
