Seedling. 200-400 (μmol/m2/s) Veg. 400-600 (μmol/m2/s) Flowering. 600-900 (μmol/m2/s) Ideally, you want to pick a grow light that outputs PAR in the ranges above. This pretty much rules out any LED grow light below 300w, as they simply don’t have enough power to generate the required levels of PAR. So in total if you’re looking to grow four plants in 3-gallon grow bags, you should set aside 44-49cm (16-17.5in) of space per plant. That’s 27-32cm for the grow bag, plus 16-17cm of space beyond the edge of the grow bag, for a total of 44-49cm per plant using 3 or 5 gallon grow bags. If you plan to grow in larger bags/buckets, you should Autoflowers, on the other hand, are usually grown under 18–24 hours of light from the seedling stage all the way through to harvest. The exact schedule varies from grower to grower, but most choose to expose plants to 18 or 20 hours of light per day. This helps to minimise cost a bit, and gives plants a brief break from the photons. Autos will struggle in cooler weather below 50°F or hotter weather above 95°F degrees. Keep in mind humidity can be hard to control outdoors. The goal is to keep the plants between 40 and 70% to avoid drying them out or increasing the chance of mold. Your garden may be a single plant or a whole plot of land. Step 2 – Topping your plant. Check before you begin topping autoflowers for signs they’ve begun flowering because you shouldn’t do it once they’re in this phase. Inspect your plants to see if tiny white hairs are sprouting at the joints. If you see them, it’s too late to begin the process. . Following your friend's friend's sister's monkey's uncle's handler's girlfriend. For a friend. A friend of mine has the same setup. He used fox farms and 3 gallon pots, technaflora nutes, 20/4. His light was similarhlg100 and he grew two plants. One yielded about 120g and the other about 40 in about 3 months. 2x2x4. Take the recommended dosage to with a 1/3 or maybe even 1/4 of that dose per gallon. So if they say 1 tsp per gallon, go with 1/4 tsp per gallon. Less is more, and autoflowers are generally sensitive to nutes. IMHO, ppm measurements just add to the confusing unless your growing hydro. Use an EC meter - An EC/TDS meter can help you determine whether your nutrient solution is too strong for your autoflowers. Most nutrients come with a feeding chart which indicate PPM (parts per million), or the concentration of minerals and salts present. Again, this depends on the strains your growing as well as the stage of growth. You should maintain a stable 18/6 or 20/4 light cycle throughout their full lifespan. Adjust your PH levels – autoflowering plants grow best in 6.2 to 6.8 PH for vegetative and 6.5 to 7 PH for flowering ranges when growing in soil and 5.8 to 6.2 for vegetative and 5.5 to 6.5 for flowering when grown hydroponically.
