@jakethedog, this year im trying cheap emos 19w bulbs, with removed plastic difusor. It really works, but high voltage without covering is little bit dangerous. Already hitted me 2 times :D I cant see difference on plants between sansi and this bulbs for less than quarter price. Only lifetime can be lower, they are shining 3 months without problem, 4 bulbs in distance 20cm for 60cm tall plant... Much safer what i can recommend will be ready products with promo from marshydro, spiderfarmer... etc, with dimmer. Its not cheapest, but it have much more power, dimming, hundreeds od leds, deatachable led driver (heat source).... Or you can buy 2-3 more sansi leds :) p.s.: look at spring discounts, sansi have promo too. I am using same bulbs for vegging vegetables in grow tent, all plants looks happy. What you need is adjust ppfd/DLI, try app for mobilephone "photone" ;) And yes, LST is way. But now too late for you. Now you need more light power. Next time: 1 bulb start with 1ft distance from germinating to 1st week veg, then each week 1" lower. After 2nd veg week apply LST. 4th week after plant stretch increase light distance with more light power (at least 60w). Now you have maybe 600umol at top of plant, but lower leaves (at 0-60cm) do not receive enough light (less than 150micromoles is useless). This is reason, why is better use strong lamps (150w or more) with higher position... If you have at 2feet distance 600micromoles, 1 feet lower your plant receive still enought (+-300umoles) With this one 24w sansi you have 600umoles at 0,5ft, but 1 feet lower you have 1/4 of light. And this is not good.
